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!!!
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)
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.
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
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.
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!!!!!
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
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.
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
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
وعليكم السلام ورحمــة الله وبـركاتــه ما شـــــــــــــاء الله Good Job, I am a regular watcher of your videos, All your videos are very much informative.
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.
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.
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
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.
Nice . Sir kindly make a vidoe on trench gate igbt. What is trench gate , what is benefits & is the without tranch gate igbt can use in that circuit where the recomended trench gate igbt or not ?
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??
Sir,I'm a little confused at the ending.To replace a new one or two ,do I I have to Discharge the gate or Charge the gate first of both IGBTs?Thank you so much for your teaching Sir.
This is very great video , I was really impressed your work , I watch so many video your , I really if you so more video Micro controller programming, or guide me how to learnt this
Mr Haseeb Thanks for your videos.I learnt alot from them. I have a question,could mosfet replaced with igbt in smps circuits if they have the same current and voltage ratings Thanks

yes dear we have to select the correct part number with same specifications
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
yes dear. you are right, we have to learn from mistakes and we have to find out the root cause of any failure
VERY INFORMATIVE. THANK YOU BROTHER!.. 15MINS of full knowledge.
thanks a lot

وعليكم السلام ورحمة الله from Morocco ❤️
most welcome dear brother
very good good luck

When checking continuty Ol means Open loop not not over load please correct it bro,, 😊
My benchtop multimeter displays "OVER LOAD" in resistance measurement mode when the leads are just floating. So... 😊
Sir,I'm a little confused at the ending.To replace a new one or two ,do I I have to Discharge the gate or Charge the gate first of both IGBTs?Thank you so much for your teaching Sir.
This is very great video , I was really impressed your work , I watch so many video your , I really if you so more video Micro controller programming, or guide me how to learnt this
Esselamu alejkum koja je razlika između originala i kopija sa ali expressa. Mislim na sve općenito komponente. Utičel mnogo na funkcionalnost uređaja.
Thank U for Your manuals like this...Its really helpfull👍🏻😊
My pleasure 😊
Thank you for your very didactic explanations. You get a new subscriber in Brazil.
Awesome, thank you!
Mr Haseeb
Thanks for your videos.I learnt alot from them.
I have a question,could mosfet replaced with igbt in smps circuits if they have the same current and voltage ratings
Thanks
you had it on Ohms range; it shd be one more notch to the right,to diode mode, not ohms, or was that the right way?
Good job
Thank u sir for this video , can we add externally a diode if not found the exact number with letter D ?
Jazakallahu bi khair, shukran kasiran
Very useful video ❤
شرح ممتاز وواضح
Hello I like your videos, could you tell me please it the 40n60npfd is equivalent to bt40t60anf? Greetings to you.
Very nice video

Which field should I study to understand such things in advanced ways
electronics engineering is awesome
because I spent more than 35 years so I love my field
Sir one doubt why we have to discharge gate purpose of this what?
in test we discharge the gate for verification that the igbt is working properly
very informative video, thanks for sharing
Wow great sharing👌👌👌👌👌
Sir jis igbt mein diode nhi hai kia hum us mein collector or emitter mein diode laga saktay hain.
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
