Hello,
I'm repairing a power supply that has multiple IGBTs.
The shorted IGBTs that has C-E resistance of couple Ohms are easy to know that they are broken.
But what about those that have C-E resistance in the Kilo Ohms instead of Mega Ohms, should I consider those dead, damaged or correctly functioning?
Note: the original C-E resistance is around 2.5 MOhms, now its around 8.5 KOhms.
Thank you in advance.
