Paul, I just wanted to show you yet another configuration for the power section. The mosfets are only rated at 75 amps, 280 volts, which is why there are so many of them; but at $1.35 each, I thought I would give it a try. One advantage of this configuration is that there are no thermal pads under the diodes or the mosfets, and I have 20 square inches of contact with the heat sinks.
