Good day, please i have been working on boost pfc charging, but i am having some issues, My issues are:
1. I cant not get up to 20Amps charging current,when i go above 9amps my mosfet gets very hot even after turning on the fan, and the mosfet i mounted on a heat sink
2. The low side mofset (either right or left side) blows.
i am driving the mosfet with a pic16 pwm, please i would really appreciate any ideas, i have attached the circuit diagram,
