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.

One of the most important points that should be consider is: to recognize "Counterfeit" Components from the "Original" ones. Counterfeit components make us "CONFUSE"
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 🇵🇭
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.
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.
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.
@@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.
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.
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.
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.
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?
@@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
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.
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.
Sir we have a ador mig 600 welding it's igbt burn frequently, so I cheek this machine igbt input DC series with a indutor coil and a 1ph bridge + ,- only connection with coils it's damage it may be course of igbt burn ?
Very keenly explanation You try to explain, is very much helpful to me , but in our repairing table please teaching us the pin point tips for quick rectify the equipment ,kindly help me for the substitute for IGBT RJH 60F7, Which is currently not available in local stores, thanks for sharing the great technical teaching,
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
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.

clear explanation. if we are using polarized capacitor then it will not affect the capacitor changing the direction of charging current from inductor.

@@HaseebElectronics my concern is that reason for igbt blown out is same as fuse example current rating or voltage
