The following image that contains my circuit is simplified for this post. It works, but the losses are ridiculous due to the diodes! The pulsed current through the inductor is around 50 amps, and lasts only for a few hundred microseconds at most. The inductance is very low. As you know, a MOSFET's Vsd (back voltage) is ridiculously low, and can't block much, hence the diode. Now I can place enough MOSFET's in- parallel to achieve low on-resistance, and the capacitance is low enough, but as far as placing diodes in-parallel it doesn't do much good beyond a few diodes.
Any ideas would be greatly appreciated!
