How to test IGBT Brick having 13 IGBTs inside it ?

Hey Gentleman!
Hi
I think your mean is that you want to test your IGBT ( is intact or not?). if yes, your answer is simple! if you give +15 volts between gate to emitter of your IGBT , Its collector , emitter junction , will become short circuit( approximately). if you can see this behavior , your IGBT is intact.

what do you mean by intact ?
I have taken it out from the inverter. Kindly, provide the circuit (dchematic) to apply +15 V between emitter & gate and what to measure between collector & emitter junction .......... ??
 

Hey Dude!
Again Hi
My mean by intact is : that can work as well as ( it is not destroyed).
You can test it with this simple circuit igbt.JPG
Or you can use a tester in collector to emitter junction.

what do you mean by "tester" (Or you can use a tester in collector to emitter junction.) ?

And, how can you use this circuit that you provide in the JPEG to test the IGBT brick (module) having 13 IGBTs inside ?

thanks
 

Hey Gentleman!
Again hi
My mean is that you can use a voltmeter and if you give a command to gate- emitter of IGBT , ( use my circuit) voltage across The collector emitter will become zero ( approximately) and if you cut the command , from gate to amitter , voltage across The collector to emitter will being +VCC. and you should test each IGBT of this package ( one by one).
And it is very simple.
I hope that this become helpful!
All the best
Goldsmith
