Dear sir,
I'm repairing one Induction cooker, when receive from my customer cooker no power, i check found fuse and IGBT are shorted. I also check 2 transistor driver S8050 and S8550 are OK, diode N4148 is ok. I replace new IGBT and use one bulb 60w replace for fuse, turn on cooker but cooker not run, pls refer my video as link"
". To make sure problem is not solved I replace new fuse for bulb 60w and turn on cooker, and again fuse and IGBT shorted, cooker die again. I trying replace new N4148 but problem not solved. I trying to measure voltage at pin G of IGBT have voltage about 1 to 4VDC (voltage waver from 1 to 4 VDC), these are images of it:
