High side IGBT damaging 2 switch forward converter
Hello guys i want to ask few things:
1: how to calculate resistor and capictor values of snubber circuit.
2: i'm testing this circuit and with 60v on output and 6.5 ohm resistive load the high side mosfet burns could someone please help me?
sorry for my bad english.
thanks

some mistakes:
1: high side and low side igbts burns i checked it now
and here are some waveforms coming from hcpl-3120
