Hi Paul:
Where can I get a schematic of the thing?
I have about 6 years of design experience with offline SMPS, so I might be
able to analyze it and maybe suggest a few tings.
73 and all the best:

Hi Roger,
Thanks for the reply. I honestly don't know how to figure that out, I
would love to learn though!
The part(s) I am using for the h-bridge are Fairchild FDH45N50F. They are
rated at 500V and 45A. The input to these is 0 - 340 V pulsed DC at 100 Khz
50% duty cycle, I expect that they might be a max of about five amps through
them when under full load. It actually looks like only two mosfets would
be conducting at the same time, so I suspect the dissipation is also about
50% duty cycle.
73,
Paul, kg7hf

How many watts will they be dissipating?
