Hurray! Tomorrow is payday! I'm ordering 25 feet of 10 gauge magnet wire, and a 3" outer diameter, 2" inner diameter toroid to make my own high power inductor. If the calculations are to be believed, it will be 300uH. At 100 amps it will have 200 watts of heat loss just from the copper.

It will have to be submersed in water, just like the Myth, the Man, the Legend... Jack Bauer did it!!!

I also ordered some 10 gauge Nichrome resistance wire to add some resistance in series with the inductance. It will allow for a nice little test bench to see just what the voltage spikes are doing in the controller, and in a new prototype I'm going to try to do over christmas break.
