Thanks Peepaw this video was a massive help. Having some issues with a IGBT stack off vacon NX drive. I didnt find a issue with converter or the brake chopper but this did help me with my faultfinding. Best tutorial i hope you get some kind of kickback.
I have problem with SMD bidirectional TVS diodes code , i have VFD to repair but some SMD TVS i dont know how to find it . Do you know how to find SMD TVS ? some code printed on SMD are not correct but i cant use any type. only the type that used by the manufacturer who manufactured the VFD.
I have started to work on traction system on subways and there is a problem which we couldn't solve with my coworkers that is the burning failure of c/I unit. The igbt of converter/inverter unit is burning time to time. This failure happens more especially in one train comparing others. We changed it with new ones, talked with producer but couldn't find the reason. Do you have any idea?we are testing the fiber cable and other cables. Do you have any comments on this matter?
Do you have the model of the machine and converter/inverter board? Do all the boards fail in the same way? is it always in a particular motor phase (U, V or W) ?Does it fail in the rectification area ? You can focus your trouble answering those question. I hope you already fixed it and can tell us how you did it
I have a question my friend so the snubber capacitor like you said in the comments that removes the current spikes and that's right I think so my question is what do you think will happen if you don't use one ???? for the record I have been making alot of Igbts like six one of them to drive a motor but failed I think because I didnt use snubber do you think that this is my problem please want to hear from you......
Thank you very much for watching my videos. I am glad you liked the video. It is great to hear from other folks who enjoy electronic troubleshooting. Again, thank you.
Peepaw that was the clearest explication I every seen. Thank you R.Y.

It's wonderful practical lecture indeed keep the fire burning boss.
Great sir........well done,your good teacher.....
Cheers from Denmark 🇩🇰
Thank you. You are a great teacher.
Thank you for this explanation but one more question is for you how to find gate driver section fault on servo drive which components should I check ?
thank you so much Peepaw. that was great.
great inforrmation and please make videos on fully troubleshooting
super explanation Mr Donald
Very much Appreciate if you explain what is the use of brake regenerative?
I really enjoy watching your video ,
very helpful thanks a lot
Thank you so much for the explanation! Great video, you are the best master..
Great video, thank you so much for the explanation!
Thanks a whole lot for this stepwise explanation, Great one there!
I am very happy that you enjoyed my video. I am always glad to see other folks interested in electronic repair. Thank you so much for watching.
Please, can you give a practical demonstration on how to diagnose the gate fire circuitry.
Thank you for your perfect explanation
Thank you a lot Mr Donald 😊
Great video good job thanks for sharing information
Thank you so much for the explanation! Great video. Keep up the good work!
Great video,thanks for the great explanation.
thank you! I learned a lot from you

Super explained sir ,very help full video .t
Thank u sir
Very clear explanation Sir, Thank you so much!
Thank you very much for stopping by. I am very glad you enjoyed my video:)
Please make video on igbt module battery lamp test
excelente vídeo, gracias por compartir tus conocimientos
I have 2 that has no led lights on the alarm display h106 model hope you show a fix on this one day

Really I enjoy watching this vedio thanx a lot I ve alot of question for you... Cheers from egypt
Please I need your help on how to trouble shoot bad drive Siemens micromaster 440 ...it stop working completely
I have a question my friend so the snubber capacitor like you said in the comments that removes the current spikes and that's right I think so my question is what do you think will happen if you don't use one ????
for the record I have been making alot of Igbts like six one of them to drive a motor but failed I think because I didnt use snubber
do you think that this is my problem
please want to hear from you......
Very good video thank you so much
If there's something wrong in IGBT it possible the 414 alarm on fanuc
Thank you so much. I like power electronic.
Hello, McDonald.
My drive fanuc show this alarm sv0603- (x) inv. Alarme IPM.
Can be module igbt? Status 2 = 8 and Status 1 = 58
Thanks
Great explanation, many thanks
So good video thanks
My vsd is ABB the output out to low normally 380v but it out 19v do you think problem from?
Good explalnation and very usefull
checking of igbt module 6MBP75SR120 and its pin confegration please
excellent . thanks .
Nice explaination
thank you very much for excellent explanation
Thank you very much for watching my videos. I am glad you liked the video. It is great to hear from other folks who enjoy electronic troubleshooting. Again, thank you.
SUPER EXPLANATION T Q SIR
Pin confegration and checking of igbt module 6mbp75rs120 of fuji
Is this igbt capable of 60volt x 300amp?
Thank to you
Great job thank you peepaw
Thanks you so much
Name of module?
Thank you so much
Thank
thanks peepaw
yea in real world divided be zero is NOT zero! its boom! heat and smoke! the milliohm resistance . makes heat fast with that much power.
300 Vdc /0 = BOOM
Please, can you give a practical demonstration on how to diagnose the gate fire circuitry.
