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!!!

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.

You are very knowledgeable person in electronics field...good luck from india ❤️❤️❤️🙏🙏🙏

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

I love the way you explain. Even lay man can understand the concepts. Well done. My heart full appreciation to 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!!!!!

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.

Another incredibly helpful and informative video. Thank you so much for taking the time to share your knowledge and practical experience. Invaluable.

Always you present wonderful ideas and useful information ہمیشہ آپ شاندار خیالات اور مفید معلومات پیش کرتے ہیں۔

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

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.

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 a lot. It's very useful. I'm trying to repair a welder from more months without result. I'll try your new hints. Thank you

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

Sir ur explaining skills are very exemplary!!!cool & technically understanding. Pls keep it up.

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.

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

Excellent explanation.I learn lot of things from you.Always waiting for your new new concept video.Thank you,Sir.

Carry on with your good work from Malaysia 🇲🇾

Good evening brother. I hope my whole family is doing well. Great informative sharing as always.

Thanks very very good informative topic, your explaination is the best in all videos....

Thanks You again and again Sir, for uploading such great informative technical video, God bless You, Stay Safe and blessed.

Informative video for testing IGBTs

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

Wow great sharing👌👌👌👌👌

L like you and adora you so much. RESPECT MAN

Excellent, great.

excellent. nicely explained

great video , great teacher ,thanks...

Well explained.

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

Good tutorial. Thank you

Very informative bhaijan

Thanks for your convenience ✌✌✌✌✌✌

Awesome, only electronic pro knows 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

Good job

Thanks for sharing, connected

Jazakallahu bi khair, shukran kasiran

Well done 👍

very clear explanation. can you possible to explain scr, diac and triac as it is above.

Thanks for sharing

Super!

Nice performance My brother 😍 give you super 👍 keep safe

A masterclass.

Wooow superb explanation

ma shaa Allah Sir, god bless you.

Thank u sir your great

Wa alaikum assalam Mashaallah wonderful sharing, stay blessed and stay connected, big thumbs up 👍

very good good luck

Thank you very much

nice work dear bro thanks for sharing, stay happy and safe

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??

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.

Waalaikumussalam wr wb Good sharing brother 👍❤️

Nice sharing

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

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

Wonderful video dear friend, happy new month!!!
