In many situations, we need to use MOSFETs configured as high-side switches. Many a times we need to use MOSFETs configured as high-side and low-side switches.
Such as in bridge circuits. In half-bridge circuits, we have 1 high-side MOSFET and 1 low-side MOSFET. In full-bridge circuits we have 2 high-side MOSFETs and 2 low-side MOSFETs. In such situations, there is a need to use high-side drive circuitry alongside low-side drive circuitry. The most common way of driving MOSFETs in such cases is to use high-low side MOSFET drivers. Undoubtedly, the most popular such driver chip is the IR2110.
And in this article/tutorial, I will talk about the IR2110. It is common practice to use VDD = +5V. When VDD = +5V, the logic 1 input threshold is slightly higher than 3V.
Thus when VDD = +5V, the IR2110 can be used to drive loads when input “1” is higher than 3 point something volts. This means that it can be used for almost all circuits, since most circuits tend to have around 5V outputs. When you’re using microcontrollers the output voltage will be higher than 4V (when the microcontroller has VDD = +5V, which is quite common). When you’re using SG3525 or TL494 or other PWM controller, you are probably going to have them powered off greater than 10V, meaning the outputs will be higher than 8V when high. So, the IR2110 can be easily used. HIN and LIN are the logic inputs.
A high signal to HIN means that you want to drive the high-side MOSFET, meaning a high output is provided on HO. A low signal to HIN means that you want to turn off the high-side MOSFET, meaning a low output is provided on HO. The output to HO – high or low – is not with respect to ground, but with respect to VS. We will soon see how a bootstrap circuitry (diode + capacitor) – utilizing VCC, VB and VS – is used to provide the floating supply to drive the MOSFET. VS is the high side floating supply return.
When high, the level on HO is equal to the level on VB, with respect to VS. When low, the level on HO is equal to VS, with respect to VS, effectively zero.
D1, C1 and C2 along with the IR2110 form the bootstrap circuitry. When LIN = 1 and Q2 is on, C1 and C2 get charged to the level on VB, which is one diode drop below +VCC. When LIN = 0 and HIN = 1, this charge on the C1 and C2 is used to add the extra voltage – VB in this case – above the source level of Q1 to drive the Q1 in high-side configuration. A large enough capacitance must be chosen for C1 so that it can supply the charge required to keep Q1 on for all the time.
C1 must also not be too large that charging is too slow and the voltage level does not rise sufficiently to keep the MOSFET on. The higher the on time, the higher the required capacitance. Thus, the lower the frequency, the higher the required capacitance for C1. The higher the duty cycle, the higher the required capacitance for C1. Yes, there are formulae available for calculating the capacitance. However, there are many parameters involved, some of which we may not know – for example, the capacitor leakage current. So, I just estimate the required capacitance.
For low frequencies such as 50Hz, I use between 47 µF and 68 µF capacitance. For high frequencies like 30kHz to 50kHz, I use between 4.7 µF and 22 µF. Since we’re using an electrolytic capacitor, a ceramic capacitor should be used in parallel with this capacitor. The ceramic capacitor is not required if the bootstrap capacitor is tantalum.
Hi, P-channel MOSFETs almost always have a maximum VGS rating of -20V, but sometimes -30V. So, when the supply voltage is greater than 20V (or 30V for the ones with -30V VGS), you can't pull the gate to ground because doing so will destroy the MOSFET. A voltage level shifter/translator is required in such cases. P-channel MOSFETs tend to have higher on-state resistances than similarly rated N-channel MOSFETs, so you will have higher losses for same/similar currents.
Thus N-channel MOSFETs are preferred. Moreover, for high voltages, finding suitable P-channel MOSFETs is quite a difficult task and the level shifter circuit is more complicated than the bootstrap circuit.
Regards, Tahmid. Hi, I have talked about the capacitor in the article/tutorial. You can find it in the paragraph right below Fig.
For simplicity I am posting the capacitor related section here: 'A large enough capacitance must be chosen for C1 so that it can supply the charge required to keep Q1 on for all the time. C1 must also not be too large that charging is too slow and the voltage level does not rise sufficiently to keep the MOSFET on. The higher the on time, the higher the required capacitance. Thus, the lower the frequency, the higher the required capacitance for C1. The higher the duty cycle, the higher the required capacitance for C1. Yes, there are formulae available for calculating the capacitance. However, there are many parameters involved, some of which we may not know – for example, the capacitor leakage current.
So, I just estimate the required capacitance. For low frequencies such as 50Hz, I use between 47µF and 68µF capacitance. For high frequencies like 30kHz to 50kHz, I use between 4.7µF and 22µF. Since we’re using an electrolytic capacitor, a ceramic capacitor should be used in parallel with this capacitor. The ceramic capacitor is not required if the bootstrap capacitor is tantalum.' Regards, Tahmid. In the high-side configuration, the MOSFET (I'm referring to N-channel here), the drain is connected to V+ while load is connected between source and ground.
Let's say V+ is 12V. When the MOSFET is on, 12V is across the load. So, source is at +12V potential with respect to ground.
So, if you were driving the MOSFET with 12V (with respect to ground), VGS is now equal to 0V. You need to drive the MOSFET with VGS = 8V to fully turn it on. And so, to drive the high-side MOSFET in the example above, you need to drive it with 24V (with respect to ground) or any other 12V source (12V between gate and source). This can be from an isolated supply or bootstrapping method, where the additional 12V above source is achieved using the capacitor.
Hope this helps! Regards, Tahmid. Hi tahmid, But i thought that the maximum gate of MOSFET only can be support up to 15-20V only? First, im connecting 4 quadrant full bridge power mosfet as well.
I found that, a lot of theory state that ' to turn on an n-channel FET, a gate voltage must higher that the source voltage'. So, if Vpower supply =12 and VDD=15 and it surely can turn on the mosfet as well. But how about if Vpower supply=50 and VDD=15 and it sure cannot turn on the mosfet right? Because the gate voltage is not higher that the source voltage right? The gate of the MOSFET can only withstand 15V to 20V WITH RESPECT TO SOURCE.
If source is at 300V, then the gate can withstand up to 320V with respect to ground, which is 20V with respect to source. To turn the MOSFET on fully would require at least approximately 308V with respect to ground if the drive circuit is ground referenced. The IR2110 circuit uses VCC (not VDD), the bootstrap diode and the bootstrap capacitor to create the additional required voltage. The capacitor charges to (VCC - Vb)V when the high side MOSFET is on and VS is pulled to ground. When VS is no longer pulled to ground, the capacitor has a potential difference of (VCC - VB)V across it.
The capacitor -ve is connected to VS which is the MOSFET source and so, the MOSFET gate is driven with a voltage higher than MOSFET source by as much as (VCC - VB)V. Of course the capacitor must be large enough that the potential difference across it doesn't drop too low for the MOSFET drive. I hope that answers your question. If you have any doubts, feel free to ask.

Regards, Tahmid. Please go through this to know about the benefit of the 1k resistor: - Importance of the gate-to-source resistor: It prevents accidental turn on of the MOSFET by external noise usually at startup when the gate is floating. The MOSFET may sometimes turn on with a floating gate because of the internal drain to gate 'Miller' capacitance. A gate to source resistor acts as a pull-down to ensure a low level for the MOSFET.
I have had MOSFETs blowing up in high voltage circuits, without the resistor in place. In most of the commercial power supplies / inverters I have seen, there is a 1k resistor used. A similar experience is narrated in Sanajaya Maniktala's 'Switching Power Supplies A to Z'.
Rachel portman midi files. This is also talked of in Raymond Mack's 'Switching Power Supplies Demystified'. Using the diodes is good practice, but in most cases is unnecessary if you provide adequate heatsinking to deal with the added heating, and if you aren't switching at really high frequencies (few hundreds of kiloHertz). Usually, these diodes aren't required (frequency. Anonymous hi tahmid i built a 220V high frequency inverter operating it from a 12VDC battery however i adjusted the secondary winding of the transformer to operate from a 24VDC battery i run into problems like blowing out the fets in the DC TO DC stage could this be because i had not adjusted the primary turns of the transformer At 12VDC the primary turns is 3 turns center tapped 3 turns with secondary 90 turns and at 24VDC i have the same primary turns with secondary 45 turns could you please help me to find out where i am going wrong please help me out thanks and keep up the good work.
The output of an SG3525 based H-bridge circuit will be modified sine wave. For pure sine wave, you should use microcontroller. You can find quite a lot of tutorials on sine wave generation on my blog: No, you can't use that. The SG3525 can provide so little current. You can simply use a 7805 regulator that gets its input from the VDD powering the circuit.
The circuit will obviously depend on your specifications. If you can't find IR2110, there are many other high-low side drivers available, although chances are that if you can't find IR2110 (which is probably the most popular high-low side driver), you can't find the otheres. Some alternatives: IR2113, L6385E, NCP5181, etc. Regards, Tahmid. Anonymous Hello Tahmid, My project includes a TL494 to module a audio signal.
I am using the IR2110 to drive the half MOSFETS bridge. I use VCC=10V, VDD=5V, the signal comming from TL494 is a PWM 0-5V and 150kHz, it worked, but i have my wave on the gate of MOSFETS something like this: My output is a Capacitor with the Speaker in series to ground, and the mosfet supply is 10V. My teacher said, that i was going to have trouble with this high switching frequency, but it must be high have a better sound. Do you have and tip about something to reduce this effect? Hi Tahmid, Thank you for all the knowledge that you share with everyone.
I am having issues with my inverter circuit using IGBTs with an H-bridge configuration. It is a pure sine wave inverter with a battery bank of 24V with an out 220VAC using a step up transformer. I am using the configuration in figure 7 along with a PIC684 with the sine wave code. The output of the H-bridge seems to be good but I am having problems filtering the signal. I have tried different methods to filter the output but with very little success. I have tried using an LC filter with an inductance of 0.75mH (Choke to be more specific) and different capacitor values (ranging between 0.45uf-40uF).
Inductor values higher than that are very expensive. Is there an inductance range that you recommend using for filtering and is there a specific type of capacitor that is needed. I know they have to be non-polarized but it there a specific type you recommend (can starter capacitor be used).
The output is very distorted and as I increase the capacitance the IR2110s gets damaged. The best result that I have been able to get has been using an RC filter but the power losses are tremendous and the waveform is not as clean as it should look like. I am using 47uF(rated for 50VDC) bootstrap capacitors for the high side of the drivers.
Here are some of my favorite power-ups: • Explosive Ball: Pretty self-explanatory. Download game magic ball 2 new worlds full version. • Yo-Yo: Attaches your ball to your paddle via a rope, allowing you to move your paddle around and swing your ball; Very cool, and very, very fun. When the ball collides with a block, it creates an explosion that destroys nearby blocks as well.
Have you experience the output the drivers getting damaged either the high side or low side and if so what was the probable cause. Does the inverter have to have a load in order to see the sine wave (I have tried both). Again thank you for everything that you do and I am putting your name on my presentation in the special thanks section. I have learned a tremedous amount about inverters from your blog.
This project is going to be donated to a community in South Africa. I just want you to know that your help is not only teaching people but also helping people in need around the world.
Best regard, Pablo. Thank you for the compliments.
I'm glad that I have been able top help and wish to be able to help as many people as I can. The capacitor will usually lie in the range 1uF to 10uF. You should be able to use a starter capacitor. Avoid using too large capacitances, as, as you've seen, it damages the IR2110. The inductance will usually be much higher than the one you've used.
Try in the range 1mH to 10mH in different steps. As cost is an issue, instead of buying ready made inductors, get a few toroid cores, some wire and wind the inductors yourself, adjusting the turns to adjust the inductance. Of course, you'd need an inductance meter to verify the inductance. Or, if you know the core properties, you can calculate the number of turns. RC filters are for low power signals, not for 'power' filtering, as in the inverter, as I'm sure you already know. Here you must use LC filter.
47uF should be okay for the bootstrap capacitors. In most cases where the drivers got damaged (in my experience), it was due to not using the 1k gate-to-source/emitter resistance for the MOSFETs/IGBTs, which prevents accidental turn on of the MOSFETs/IGBTs. Make sure you have a 1k gate-to-emitter resistance for each IGBT/IGBT combination. Read about it here: The inverter should have a minimum load to observe the output. The load doesn't have to be too high though.
Few tens of watts should be okay. I hope that answers all your questions.
Feel free to ask if you have any further questions or doubt. I would love to see your project at work and the project paper/thesis when you're done, if you don't mind sharing.
I wish you success on your project. I hope to add more to my blog to make it even better.
Your comments and suggestions are welcome and will be highly appreciated! I hope that the project will benefit the community to which it will be donated. I'm glad to know that I am able to help people in need as well as teaching people. I hope I can continue helping and contributing. Best regards, Tahmid. Anonymous hiiiiiiiiiii i had done 12v to 310v circuit using SG3525 and work good but.
I used fig.8 with bootstrap as shown in this figure. i using sG3525 to drive the H-bridge and i leave legs (1, 2,3,4,9,16) floating i used other legs with (leg 5 0.2 micro capacitance).(leg6 150k ohm resis.).(leg7 10ohm resis.).(leg8 1micro farad capacitance).(legs 10, 12 grounded). (leg11 direct to leg 10,12 of ir2110 ). (leg14 direct to another legs 10,12 of ir2110).(leg 13,15 supply voltage 12v ).but the circuit didn't work and one of ir2110 blown!!!!!
When i use pic16f684 of your design instead of SG3525 the voltmeter read various swing readings such as ( 119,218,98.) not fixed 220v where is the problem??????? For the MOSFETs, use 1k resistor from gate to source of each MOSFET. Please go through this: That should solve the issue. If not, you will need to dig further. Don't leave all those legs floating. Go through this tutorial and then construct the correct circuit using the SG3525: Please upload your schematic to a file sharing site like rapidshare or an image hosting site like imageshack.
Without looking at the schematic, it will be difficult to spot the problem. For the PIC16F684, you must ensure that the circuit and code are both correct. Once again, you should upload the code and the schematic so that I can take a look. Regards, Tahmid. Thanks for the compliment. I'm glad you've found it helpful. Please upload your schematic to a file sharing site like rapidshare or an image hosting site like imageshack.
Without looking at the schematic, it will be difficult to spot the problem. If you're using one of the circuits I've provided, please mention which one, along with any modifications you've made. Where does the drive signal come from? Is the drive signal okay? What's the driving frequency and the duty cycle? You must ensure that the IR2110's are okay and not damaged. You might've somehow damaged one of the IR2110's (the one on the side not working).
Replace this IR2110 and see if it resolves the issue. Regards, Tahmid.
Please check all connections and make sure that you have constructed the circuit correctly. Can you post an image of the waveform from the Arduino? Have you tried replacing the MOSFETs? Maybe you have damaged MOSFETs. On the IR2110 side that doesn't work, check the voltage (with respect to ground) at pins 3, 9 and 6 with the input signals off.
With the input signals present, check the voltage (with respect to ground) at pins 3 and 9. Check the signal input to the pins 10 and 12 (use an oscilloscope). Check that pins 2, 11 and 13 are connected to ground. Let me know the values you obtain. Regards, Tahmid. Anonymous Hi Tahmid, I am now adding a post from edaboard. I added a pic that includes 4 gate signals from TL494.
L1 and L2 are output of TL494,whereas H1 and H2 inverted version of TL494 output. My problem is that when ı drive the mosfets with these 4 gate signals, high side of the mosfets become so hot. (DC Bus = 50V, it will be 311V later) I can obtain sine signal with appropriate filter. I will also ask that is this low side of the gate signals are normal? Are they supposed to be like high side of gate signals? And can ı drive whole h-bridge with using just two H1 and H2 signals, ofc Q1-Q4, Q2-Q3 will have the same gate signals.(ignore the snubbers) http://obrazki.elektroda.pl/.jpg.
You will have to choose the switching frequency as that will depend on your requirements. For example: If the H-bridge is going to drive a step up 50Hz iron core transformer, whose output will drive AC loads, then you need to use 50Hz.
If you're going to drive AC loads directly, from a high-voltage DC, then you'll need to use 50Hz. If you're going to use the H-bridge to drive a ferrite core transformer at high frequency in a DC-DC converter, the output of which will then again be converted to AC, then you need to use high frequency, typically in the range 30kHz to 100kHz. Hope this helps! Regards, Tahmid. Anonymous Hi Thanks a lot for your quick reply. I will check it out and will let you know. One more thing, is it necessary that Hin and Lin signals come from controller or can I use constant DC voltage too?
What I am doing rite now to check my Full H-Bridge circuit is I am using constant DC voltage and I have connected Hin of 1st IR2110 to Lin of second and vice versa (meaning I am controlling my bridge with 2 inputs). So do I need PWM signal from controller or can I also use constant voltage signals? I'm really glad that this article has helped you.
It provides me tremendous happiness to know that my articles are helping many people like you. The blissful feeling of helping others is a feeling paralleled by few other things. I would like to make my blog even better so that it can reach out to help many more people like you. Your comments and suggestions are welcome and will be appreciated.
Ir2110 Pdf
There are certainly some differences between IR2112 and IR2110, most important of which is the ability to use up to 600V (IR2112) as opposed to 500V (IR2110). However, I believe, you can use the two drivers interchangeably in your circuit and that you can use the IR2112 in place of the IR2110 in your circuit. The operation is the same.
Best regards, Tahmid. I'm not sure what you mean by: '1) Do I have to write a program in Arduino to switch between HIN and LIN or do I use an Inverter? And if so do you have a link to an example code.' The drive signals must come from the controller in the circuit. If the controller in your circuit is the Arduino, then of course you have to write the code to send the appropriate drive signals. However, I think using a PWM controller such as SG3525 will be easier than writing your own code for the Arduino.
Go through this: Hope this helps. To shed some light to the possible reason for your problem, answer the following questions. 1) Did you use 1k gate-to-source resistances for each MOSFET? 2) Did you filter the output of the power supply?
3) Did you ensure that the output of the 12V power supply does not rise too high? Did you ensure that the output stays relatively stable at 12V? 4) Did you check the inputs to the IR2110 to ensure that there is no cross-conduction? 5) Did you replace the IR2110 and MOSFETs and try again, in case the IR2110 and/or the MOSFETs were damaged from the beginning? One thing you should remember is that a damaged IR2110 can quite easily destroy the MOSFETs. Similarly, a damaged MOSFET can quite easily damage the IR2110.
So, you must ensure that everything is okay to avoid damaging components in your circuit. Regards, Tahmid. Anonymous I 've implemented the Half-Bridge Circuit using IR2112, but i found the motor not working well, it changes its state rapidly(ON-OFF-ON-OFF-ON-OFF.), it seems that its OFF state is too long. I have used 22uF capacitor, bit then i read in the article that for low freq. A 47u-68u should be used, I connect two other capacitors (22u), but still no changes.
The really boring thing in this circuit is that i used three different power supplies (1 for VDD,1 for VCC, and other for motor voltage). Another Note is that i didnt connect COM pin with the same ground(with VSS), but i connect it to motor ground. Thanks in advance. Anonymous Hi Tahmid, Superb tutorial! Very useful.Unfortunately i think you made a mistake, on paragraph 7 after Fig.4: 'The output on LO is with respect to ground. When high, the level on LO is equal to the level of VCC, with respect to VSS, effectively ground.' I think you mean 'effectively VCC'.
Anyway i have some questions: Should the ground of the MOSFET be connected to VSS and COM as well? My Gate-to-Source Voltage is +-20V so what is best 10,12,15V for VCC?
I'm running at 24khz so what do you think C1 should be 22uF? What do you think the maximum duty cycle is, for the bootstrap to stil work?
Would 100% work for short periouds?(to rise the current in the inductor faster) Should i use current limiting resistors betwen uC and IR2110? Thank you, Regards The M. Hi, Thanks for the compliment. I'm glad that you've found the tutorial useful.
What I meant in that sentence was that when high, the level on LO is equal to the level of VCC with respect to VSS, which (referring to VSS and not LO) is effectively ground. Perhaps the sentence structure gave rise to that confusion. But you've understood correctly. The source of the low side MOSFET should be connected to VSS and COM. 20V VGS is the maximum rating of the MOSFET.
Use 12V or 15V for VCC. Typically, anything between 10V and 18V will work properly. 12V and 15V are good since they aren't too high to be close to the maximum/upper limit but are high enough to fully drive the MOSFET. C1 = 22uF is okay. I cannot say that with certainty.
It will depend on the MOSFET as well as the bootstrap capacitor. I think that about 70% could be achievable.
You might be able to get higher, but you should still test it, since I mostly stick to around or less than 50% (since that's what my design specifications dictate). The bootstrap drive can't be used for 100% duty cycle due to inability to charge the bootstrap capacitor.
For 100% duty cycle, use an isolated power supply with isolated MOSFET gate drive. No, current limiting resistors betweeen microcontroller and IR2110 are not required.

Regards, Tahmid. Cezary Hi Tahmid, First of all, I have to admit, that Your articles are really usefull and clear. However, I am working on the BLDC motor controller.
I want to use the STM32F4Discovery board as the main unit.I have almost finished the electronic scheme but I have some questions. My inverter is based on IR2110 drivers so I must choose a right logic level translator - STM32(3.3V)IR2110(5V).Can you suggest one? STM32 board generates PWM signals with a frequency of 15kHz.I have found some ICs(ST2378ETTR,ADG3300BRUZ).Is it appripriate for 15kHz signals?
I want to use my controller witk 500 Wats BLDC motor.I have attached my scheme here(inverter and gate drivers). I will be very grateful if you check my scheme and give some advices.
Thank you a lot. Hi thamid.really appreciate the knowledge that you have shared. Just wanted to know what are the criteria to calculate the current limiting resistor for the gate in the full bridge circuit.R1 and R2. Secondly i am not very well versed in electronics.could you please explain what you mean in your reply to anonymous dated 26th april, that 100% duty cycle cannot be used with the boot strap and that u stick to around 50%.to state my problem. I wanted to use your above schematic for driving a 24V volt motor using all n channel bridge using irf540.incase i do use irf2110.do u mean to say that i wont be able to effectively drive my motor at 24volts and in actuality it would be getting 12V(50% duty cyle) and at max 16-17V(70%).
Incase i want to go for 100% duty cycle what is the alternative tlp250??? I choose a value of the current limiting resistor depending on the MOSFET used and the frequency. Usually, 10R is okay for up to about 50kHz. Above that you might use 6.8R resistor.
Mosfet H Bridge Circuit Diagram
There's an application note that talks about current limiting resistors. I'll attach the link soon. At high duty cycles, the bootstrap capacitor can't (quickly enough) fully charge and can't drive the high side MOSFET fully.
You might be able to go to up to 70% duty cycle or a little more using a large enough bootstrap capacitor. However, for higher, you should look at other drive methods. I suggest you use a separate isolated power supply along with an isolated driver such as TLP250, TLP350, HCPL3120, etc. Regards, Tahmid.
Hi Tahnid, Your blog is very impressive and helpful for innovation. I am trying to make inverter for home appliances. My circuit is as similar as you have shown in fig-8. Primary section of my step up transformer is connected to out pins as shown in fig-8. I am successfully getting 240 V AC at the primary by varying duty cycles. My transformer rating is 12V AC to 300V AC.
But now if we think about the reverse direction means if I give I/P of 230V AC to secondary of transformer I am getting about 24V DC across drain of higher side MOSFETs and source of lower side MOSFETs while all the MOSFETs are in off state. I am using IRFZ48N MOSFETs. Now I want to charge my 12V DC battery which is connected across drain of higher side MOSFETs and source of lower side MOSFETs. Means battery is connected across 24V DC. While I connect battery to charge that O/P goes down to about 10.5V and battery is not getting enough current for charging. Let me know the proper direction to get required voltage and current to charge the battery. First of all, thanks for your great help and advice.
Since the starter is manufacture connected to the ground, and p-mostet will not be able to handle such a large current to drive the motor to drive, that is why I am trying to make this n-channel mosfet to be connected to the motor to drive properly. But can I know the near current of gate for each mosfet. So that I will start to use the current limiting circuits for it. Well I have not described that I am using for my bike starter motor in which the relay refuse to return to the original position (off/no connection) after releasing the push button switch, thus draining all the current to the motor resulting to wastage of fuel on the run and damaged the battery. Hi Tahmid, reading your blogs, I am quite impressed with the way you present and explain things. I would need some help regarding IR2113 and PWM. I'm working on a grid tie inverter project where I need to supply PWM signals to HIN/LIN inputs of the 2113s driving H-bridge mosfets.
I had a look at your SG3525 blog. Would you recommend using SG3525 to generate PWM signals from 50Hz grid signal. If so, how would you go about it. The grid has lots of distortion, noise and other rubbish that somehow needs to be filtered out before a PWM could be generated (I think).
So far, I got the IR2113s and H bridge running from the grid's 50Hz using a dead-band circuit. This only generates square waves at 50 Hz in sync and uploading efficiency is questionable. I prefer a more or less good looking PWMd sine wave in sync with the grid for uploading. Any suggestions or ideas are very much appreciated, rods, Selim.
Anonymous Hi Tahmid First of all, thank you very much for helpful blog. I want to test the circuit of ir2110 before connected the MOSFET (H-bridge).I've followed the circuit in this post,but doesn't connect the MOSFET. I got the signal from LO, but the HO was 10-12 constant. May I ask you for my understand.
If I didn't connect the MOSFET, the Vs(pin5) of ir2110 have to connected to ground,that right? I can connect Vs to ground directly or have to connect the resistance before ground.
Thank you very much, Regards, Song. Anonymous Thankyou for sharing your experience/knowledge. I am building a full wave bridge controlled rectifier with power factor correction. The two drivers I used are IR2110 and the four mosfets are IR640. I used the figure 8 diagram for full bridge.
This figure shows the leg of the H bridge as the output branch. I use this leg as input, so the two Vs pins are tied to the floating input. I have followed your recomendations closely but the circuit does not working. I am guessing that the IR2110 cannot be used for rectifier applications or I am missing something or doing something wrong. Can you give me a clue where is the problema. Thank you again.

By using a single IC, a half bridge circuit can be operated in which one MOSFET is in high side configuration and another one is in the low side configuration. For driving the high side MOSFET, this IC uses a bootstrap circuit which otherwise could have to be designed externally. Before using this IC for driving the half or full bridge circuit, it is necessary to test the faultiness of the IC. A faulty IC can give unstable output and may blow up the MOSFET or other components in the circuit.
In this tutorial, the method to test the IR2110 IC is discussed. As in accordance to the pin configuration of IR2110, the SD (shutdown) pin is used to shutdown the IC. This pin is active high, so for enabling the IC to work, this pin is connected to the ground.
The VDD is the supply voltage for driving the internal circuitry of the IC and it should be in between 3V to 20 V (with reference to Vss) as per the datasheet. The VCC is directly connected to the drain of internal MOSFET of low side driver(as shown in internal circuit diagram of IR2110) and it can be in between 10V to 20V. For testing the IR 2110 IC, 5V is taken as VDD and 12V is taken as VCC.
When the input at Lin or Hin pin is high then the IC gives High output at LO or HO pin corresponding to the input supply. When logic input at Lin and Hin are low then a low is obtained at LO and HO pin.
