[436] How To Test IGBT / How to Check IGBT with Mulimeter / Why IGBT Damage

[@kostasbobos6209]

I have to give you a big thank you for your tremendous patience in creating all these very informative videos explaining in the best way I have heard so far very difficult concepts. I wish I had you as a teacher and I "envy" the children who learn from you. You are a very good teacher and a very good and selfless person who tirelessly shares what he knows well. Congratulations!!! and keep on!!!

[@HaseebElectronics]

You're very welcome! i am specially thankful for your valuable words. please accept my best regards and special thanks

[@jating001]

You can do cherity in different manners and you are doing the same. Have seen lot of videos on youtube but your concepts is very clear. One thing in this video I want to know is there any different procedure to test the igbt which is without safety diode.(you discussed two types of diode in your video)

Sir, you have done a great job by explaining very well about IGBT checking procedure. Thanks for sharing your valuable knowledge with others. May God bless you.

[@goutammukerjee6229]

The method of testing IGBT, really very properly you teach, and in future I must be able to check the transistor properly, thanks again, please be with us

[@andredeschamps1587]

Wonderful and informative video on testing IGBT's and the importance of ensuring the correct part number/charateristics. Thank you very much for your time and effort on these valuable videos!!!!!

[@HaseebElectronics]

it is my pleasure

[@HaseebElectronics]

yes dear we have to select the correct part number with same specifications

[@notreallyme7465]

I bought a new return from eBay for cheap. What I found was one entire bank of igbt's were shorted. The cause was POOR SOLDERING on one of the driver transistor pins. Easy fix and I still have the plasma cutter. As always thanks for sharing your talents and skills. Always an interesting lesson.

[@jackladthe1]

great video again you, are a great teacher , other youtubers are difficult to follow you make it so much easier

[@HaseebElectronics]

special thanks dear luckily i am not a youtuber by profession. professional youtubers seek for likes, views and subscribers. but i am sharing my experience and i try to explain it in very simplest ways as much i can. so that it may helpful

[@sublimeelectrons8699]

VERY INFORMATIVE. THANK YOU BROTHER!.. 15MINS of full knowledge.

This one is the best learning platform, also way of explaining is awesome jazakAllaha brother

[@HaseebElectronics]

most welcome dear brother

[@blackartista]

Some self-protected MOSFETs did the same to me too last year when I replace them in a place of Generic MOSFETs ... I had to blow two of them to realise my mistake ... It was a painful experience but I'm glad I learned from my mistake

[@HaseebElectronics]

yes dear. you are right, we have to learn from mistakes and we have to find out the root cause of any failure

[@LalithsMusicChamber]

Really a good explanation. You are an electronic GURU. Good luck!👍👍👍

[@HaseebElectronics]

thanks a lot for your valuable words please accept my best regards

[@W1RMD]

Thanks for this! I'd like to point out that some cheaper meters don't have enough voltage to turn on the gate. I don't know about IGBTs, but I've seen this with MOSFETS. I have a cheap variable voltage current limiting supply and it does the trick! I like how you have the data sheet just below the part. A great visual aid! I still kind of new in this level of electronic repair. I've yet to work with IGBTs.

[@HaseebElectronics]

Informative video for testing IGBTs

[@X0X0LFertilizer]

Very clear and concise videos, awesome patient easy to follow teacher. Makes it easy for people like me with zero electronics knowledge. Question for you dear sir , say you have a mosfet welder inverter machine and mosfet dies , can you replace with IGBT? Also what is the main reason these IGBT and mosfet break in welding machine? Is it heat or maybe component specification too weak / underrated for the current and power in those machines ? Can you replace with same type but higher amperage rating? Sorry for so many question this just really eagers me to know for when my Chinese inverter Tig machine or plasma cutter and mig welder break so I can know how to repair. Best wishes , health happiness and blessings from Ontario Canada! I look forward to hearing back if you see this , if not it’s ok I will just keep watching you and trying to learn on my own I guess . Love you

[@HaseebElectronics]

dear brother i am thankful for your valuable comment yes we can replace mosfets with IGBTs, just we need to re-arrange gate driving circuit, so that the gate must charge / discharge properly. oaky i noted it and i will try to do a practical tutorial on calculations and swapping the MOSFETS with IGBT and vice versa there are too many parameters for the failures of power semiconductors, i will suggest to watch video number 502 in my channel, that is on the reasons for IGBT failure

[@X0X0LFertilizer]

[@usman_oz]

Thanks for the detailed info. Between 3 - 4 minutes you touched gate and emitter with Red probe on gate and black on emitrer hence the resistance should not be high or OL as you charged the gate and didn't discharge before you checked resistance between C & E around 3:55 ? Thanks

[@impactodelsurenterprise2440]

When I measured the reverse condition, it first shows a voltage drop for a split second before backing down to O.L. why?

[@mohamedroomy111]

Very useful lesson I can say. Thank you Sahab

[@andrewmusisi7147]

Thanks Mr Haseeb for your knowledge and assistance. I was brought a Kema Inverter to repair but I suspect the IGBT pair in the synchronous active rectifier are not matched or the same, as the High Frequency solar inverter rises to 240 volt AC output then after 3 minutes indicates F14 fault which I think means low Bus voltage output. I suspect it is interfering with dead time control. What do you think could be the problem, thanks? All gate drive circuitry including resistors, optocouplers and diodes including Zener diodes test fine.

[@jaym5938]

My confusion is when you're testing the 'resistance' how do you know the reading is accurate? Where on the data sheet does it state 117.3 KOhm is the expected value? I have some IGBT's I pulled from a Godox AD300 and they seem to be fine. Their resistive value is 179kOhm, but the replacements (Mouser) are only 102KOhm. Some are 99KOhm. Are these good or are they defective? Thank you kindly.

[@mtrltoolman]

Can we add a high speed diode between collector and emitter if we can't get the same igbt?

[@HaseebElectronics]

yes we can. the current value, reverse recovery voltage, recovery time must be matched with igbt

Hi ,Haseeb thanks for your video excellent. I have a question ? I will appreciate if you can answer. I have replaced my thredmil I G B T .because getting error EO2 , I replace with new , I G B T it’s start few seconds and stop .used ( same no - fgh40N60 - ufd ) it’s damage again ,Can you advise me Thanks.

[@HaseebElectronics]

first possibility, that the IGBT is falsely marked (ot original part) second check the dc motor (may be its center is out, check its rotation by rotating it manually, and observe that shaft must rotate in center, if it is out from its center, it will need centering by machinist or add weight by balancing machine, so its rotation must be smooth ) check the bearings of the motor must be smooth and soundless check the Carbon brushes and if possible clean the commutator

[@fayewijesinghe1rodwell353]

Thanks you very much for your quick reply, I will try and let you know. thanks again for your kindness wish you all the best.Adey.

[@MuhammadDanish-xz3qt]

Sir jis igbt mein diode nhi hai kia hum us mein collector or emitter mein diode laga saktay hain.

[@HaseebElectronics]

same voltage and same current rating ka diode use kia jaa sakta he. we have to use same characteristics which are mentioned in the datasheet

in test we discharge the gate for verification that the igbt is working properly

[@sadiasyed9918]

[@nemueldolaiasi1926]

How do you identify geat ,ammeter and collector

[@HaseebElectronics]

we must consult component datasheet by following its part number

[@HaseebElectronics]

or we can identify, there is gate drive network, connected to the gate pin collector is to drive the load and emitter is connected to the ground

Thank You for helpful video. Is it OK to use current limiting supply to test MOSFET's and IGBT's on bench?? For example: adjust supply voltage and current within spec of IGBT, connect supply across emitter and collector. Then, charge gate and observe current flow and voltage drop. Then discharge gate and watch open (maybe use scope). Might this expose leakage or sluggish response?? Or the resistance and diode test is enough??
