- in this video i discussed Why IGBT Burns Out After Replacement - IGBT Damaging Reasons. the reasons and factors which are involved in IGBT failure, specially when we replace ibgt in induction cooker, inverter igbt welding machine, dc inverter ac outdoor unit boards, sewing machine inverter control board, top loading or front loading washing machine inverter boards, solar inverter boards, variable frequency drives (VFD). there are many factors involved in this scenario, material failure, how to select igbt specially VCE sat, power dissipation, zero crossing detection, resonant frequency, resonant coil, resonant capacitor, and teh gate drive components,
main root cause is the low quality standard of the components,

For better result:
1) Always check the ESR of the resonant capacitor and the internal insulation.
2) Remove all flux residue with a little brush and pure alcohol.
3) Apply electronic silicone to the solder pins of the IGBT and the driver on both sides of the PCB to prevent moisture in the air from activating the gate of the transistor.
it is really a great addition, i am personally thankful for a valuable guideline for my viewers
please accept my best regards
ما شاء الله انت كنز من المعلومات ...لقد فاجئتني عندما تكلمت باللغة العربية ....لم اجد ابدا بكل المحتوى العربي شخص بارع وضليع بالالكترونيك مثلك ..كم نحتاجك لو كان عندك قناة تتكلم فيها بالعربي ..
Thank you for explaining this is detail! I have also found it it frustrating to get reliable results when changing high power components. I always figured there was another component or "something". This video detail is very helpful for understanding what else is happening. Very well done as usual.
That is really very very informative now I understand what's the reason of burning MOSFETs and IGBT thank you so much for the very informative and easy understandable videos
Best regards from Philippines 🇵🇭
best regards and special thanks
One of the most important points that should be consider is: to recognize "Counterfeit" Components from the "Original" ones.
Counterfeit components make us "CONFUSE"
جزاك الله خير .

شكراً جزيلاً يا استاذ.
Thanks lot for your genuine effort to share your valuable knowledge. My sincere blessings
Your video was very helpful. I had changed in a mini welder the Igbt's because they burned out and one of the new one was always to hot 115 degrees Celsius one had approx 70kohm internal resistence and the other one approx 650kohm and that's why was to hot.
Thanks a lot, you make a wery good job.
wow that is really awesome
i am thankful for your valuable comment, to encourage my efforts
Good evening brother. Though I don't understand the technical things, but always like your presentation and way of explaining
Thank you very much dear sister
it is your greatness
I also recommend to use a transistor tester before you install the part so you can check the capacitance and vge. This goes also if you have a bunch of transistors you need to change, test them all and select the ones that are close in value. With all these chinese parts now sometimes there are defective parts or out of spec. Always test before install.
Pls my igbt keep burning out even when I put higher number
Best explanation sir.... Today only i know, purpose of zero current detection... Thank you very much sir... God always prosperity in your life...
You are most welcome
it is my pleasure that my efforts are useful
Hi thanks for the informative video and for the preventative ways to avoid components being destroyed
You are welcome!
it is my pleasure

ma shaa Allah
fabulous informative discussion on igbt failures. your analysis is always effective in electronics work. stay blessed dear brother
Many many thanks dear sister
@@HaseebElectronics thank you, Mr. Haseeb, you are a very respected and good person, You explain schemes and theories very well and nicely, I often watch your recommendations on your channel.
MashaAllah
Great Sharing 🌹🌹❤👍
Ma'Sha'Allah nice information sir
very well explained, bravo sir🏅🏅🏅you made technical books easy to understand and interpret
best regards and special thanks for your valuable comment
You are a very clever man, thank you for your videos
Excellent teaching. Thank you, Haseeb.
You are most welcome
Great sharing
When I saw this, I think first at the fake component avalaible on ebay and aliexpress. They are sometimes rebranded, and gate capacitance is not the same, and bandwitdh is different. THis is the reason why it works few hours, and failed when overheating.
If the capacitor of the LC circuit is dead, you will maybe just have a lack of effeciency. Thanks for the video, god bless you.
Amazingly useful information
Big Like from London 🇬🇧💌
big thanks and special thanks
Thanks for your support. However there are two thermistors in the circuit for over Temperature. So when the IGBT overheats then the Microcontroller is supposed to switch off, can you throw some light on this?
Thanks.
Very helpful information, most appreciated
best regards and special thanks
Very informative like always. Shukriya Maestro.
So nice of you
@@HaseebElectronics Maestro can you make a video explaining the meaning of connection or how does the KCM15F60GA IC works thi Ic comes in Samsung washers motor inverters please
Salam brother you showing good work and telling god bless you by 🇺🇸🙋♀️
thanks a lot dear sister
Very informative, thank you.
Could you please make video about zero cross sensing and such other sensing circuits in induction stove...
Super explanation, thank you very much, iam from India, Hyderabad, thank you 🙏💕, do more such videos
thanks a lot dear
you are most welcome
Very useful information sir thanks for sharing this knowledge to us
it is my pleasure
The video is informative, thanks for sharing.
best regards and special thanks
Hi sir..,very interested and informative video.
Thank you very much. Have a good day 🙏
thanks a lot dear
clear explanation. if we are using polarized capacitor then it will not affect the capacitor changing the direction of charging current from inductor.
Nicely explained, thank you so much
You are welcome
Really Informative Video ❤️
it is my pleasure
Masha Allah informative as always..
Many many thanks
Very useful fault finding method. Thanks
You're welcome
Very GOOD video, Sir. Sourcing components is HUGE issue. Too much falsely marked JUNK from non-authorized-distributors. Sometimes seems quicker or cheaper, but not really; and clients get mad when equipment down over and over. Now, in USA, i ONLY buy from Digikey and Mouser. Clients and me are happy to get OE performance out of repaired equipment.
thanks a lot and lovely thanks
you are absolutely right that component sourcing and falsely marked components are biggest headache and loss of money. and biggest issue the client's trust.
please accept my best regards
السلام عليكم و رحمة الله
جعل الله لك هذا العمل في ميزان حسناتك يوم القيامة.
Excellent explanation. I hope you do a design example with testing experiment of an induction heater. I am very interesting with induction heater, it is very tricky.

una pregunta el datasheet q tomas como referencia a que igbt (numeración ) pertenece. muy buena explicación
I have Induction cooker . Replaced igbt pair already. But nearby ZD diode also shorted. The diode in other side of cooker reads as normal diode perhaps IN 4148. Do u think is standard N4148 is ok to replace?
ماشاءاللہ ماشاءاللہ بہت خوب*
very great sir.. thanks..
Most welcome
Realy u r genious
Hi Haseeb. My capacitor is 800V 0,25micro farad. I measured 230 nano farad. Is that problem. Also I have 4 IGBT who works on two couples for each end of the coil. One of the couple give me a short circuit if I measuring on board. If desoldering them their value are normal. This their condition is same if there is no power on the motherboard. I had short circuit damage and one IGBT was burned. Also big diode between rectifier and IGBT. What is your opinion. I ordered other three IGBT to replace them too.
وعليكم السلام great people have always fantastic output
best regards and special thanks
thanks very much sir for sharing...god bless.
You are very welcome
Nice
aslaam brother, sukraan for the indepth teaching of Why IGBT keeps on popping, am working on a cooktek induction single hob, fuse keep on popping when I replace it and it has 4 inline IGBT 's, and I was thinking before I put in the new ones, reasoning to myself why and your video just made it clear the reason why it keeps on burning out because of the coil or maybe something els, can you give another explanation on it kanalah.
Great 🌹
Thanks for the visit

Jazaak Allah khair
When choosing a replacement IGBT, don't forget to check whether or not the component you are replacing and your replacement component have an internal flyback diode! Most modern devices contain this, but not all. Always check your datasheets.
Don't assume that adding one where there was not one before is a good idea. Generally it is best to use the exact same part the manufacturer used whenever possible.
Dear Haseeb. My treadmill 's IGBT keeps burning within few seconds 😢. Could you please explain why?
Brother i have an induction model-prestige 16.0 ,
in the drive section 8050 pnp transistor was open circuit i replace it and induction worked for several days and after that again the igbt went short circuited 😢😢😥 plz help me
New friend ✅
Jazaak Allah khair
thanks for joining
Bai me welding machine me igbt lagata hoon to forn patakha marti he jab k transformer ki jaga output me bulb lagao to thek operat hoti he bilkul thek on of hoti he through dri circuit .lekin jese hi output transformer wali wire conect kre to on krte hi jal jati he.kia transformer to kharab ni jab k transformer k bad rectifier diod module b thek he.plz help n ap igbt se age output tak video bnae.
valekum salam elder brother how are you
thanks a lot dear brother
جميل watsapp
thanks a lot
اللهم صل على سيدنا محمد
I have this problem on a barand new Induction cooker for the last 6 months still NOT rectified. I wish to contact you on WA or email
if possible. Thanks.
Jazikela for sporting 🙏😭
best regards and special thanks
I have the same problem.
snubber circuits need replacing
in resonant circuit, most of time there is not snubber circuit. because in induction cooker the resonant technique is used
snubber is in fluback topology
Sir make this video in urdo.
کل ان شاءاللہ حسیب الیکٹرونکس اردو چینل ہر ملے گی
Bosss short vedio bnaen
i will try my best, but it is impossible to explain clearly in short videos
but i will try my best
please accept my best regards
@@HaseebElectronics my concern is that reason for igbt blown out is same as fuse example current rating or voltage
@@ehsanuddin7706 the biggest headache is fake marking numbers
may that is not that igbt but it it named by fake marking
sometimes quality failed components are supplied
always try to purchase from some reliable source
Vge parameter
Asalam alaikum,
Very nice, could you please explain the driving circuit of IGBT with circuit diagram....or share me the video inwhich you already done this...
