A few brave builders have requested seeing the schematic to help me.
I've uploaded the full schematic here:
http://home.comcast.net/~kg7hf/FULL_amp.pdf
The last page (4) is the h-bridge portion. It seems the key is to
understand what the dissipation through the h-bridge is during normal amplifier
key - down. The schematic is for a single 3cx800, however I want to build in
enough margin for two 3cx800's.
So, how do you figure out the power dissipation through a mosfet being used as
a switch operating at 100 khz at 50% duty cycle in order to figure out how much
heat sink to use?
Thanks,
Paul, kg7hf
