PROBLEM
I AM TRYING TO BUILD A FULL BRIDGE HIGH VOLTAGE 50 HzINVERTER (300V DC).
WHEN SWITCH ON THIS MOSFET WILL DAMAGED.I HAVE RECTIFIED 230 V AC .
used Fan7392 driver
SOLUTIONS THAT I HAVE ADDED
MOV OF 320V ,20mm dia
1uF polyester capacitor across dc 300v power supply bus
common mode choke- ferrite connected series with dc bus and inverted card
- uf4007 -fast recovery diode across ground and high side mosfet source in reverse bias
- gate resistor of 100ohm (previously it was 10 )
- 15v zenor across driver power supply
- 1n4148 diode across gate resistor for fast turn off
- 15v zenor across gate and source of mosfet
