interleaved PFC boost converter

I am designing an interleaved PFC boost converter to convert 220vac to 400vdc, the fuse keeps breaking anytime I apply PWM to the gate of the MOSFET, I have tried reducing the duty cycle of the PWM it still keeps breaking my fuse and damaging my MOSFET.
let me attach the circuit.
Thank you.

Well you haven't attached a 'circuit', that is only a crude part of one, and doesn't even give any clue what most of the circuit is.

Or you can post on every forum you can find and not answer questions.

I think design is an overstatement. It looks more like 'copy & paste'. Good luck with that, assuming you survive the initial debug phase.
