Hi,
Here is my circuit
I use a IGBT(VCE>800 , IC=35) instead of BJT transistor with a IGBT driver(VCC=15v). I want to get a 1A current output with switching frequency 50khz (duty cyle less than 15%).
However after I inject 220VAC as input my IGBT gone and after that all my circuit behind of gate such as IGBT driver , PWM generator has gone too.
what is my mistake?
