I have tested my new converter design and have gotten great results! Current draw was 10amps with the supply bus at 50vdc. The circuit runs very smoothly at this power level. I'm using a 50 ohm power resistor as a load. Tommorrow I will try my first test with the secondary! I am controlling the voltage with a variac so I can get the sucker in tune at low power before I give it the works. I probably could push it a little harder but I don't have the guts! I'm posting the circuit to the image list in case anyone is interested.
