I want to upgrade a 2.5kW ZVS flyback PCB to Wolfspeed SiC FETS and Shottky Diodes. I have #6 IRFP260Ns, TO-247AC on the board now.
We need faster switching and better thermal management and would like to change out to #2
C3M0021120D or similar, and add diodes and gate drives.
We need some advice on several levels:
- Can we or should we move these components off the board?
- Can we replace 6 200Vdss with 2 1200Vdss? Any penalties or hazards?
