Thanks Paul,
That is basically what i got from the electrical engineer that I asked here at work. She recommended that i research flyback transformers for information. Those are just high-powered coils, too, like a motor.
600A @ 1V = 600W burned off in the diodes...
Say you put together a mere 10 mosfets for flyback - say 0.014ohm each, you'd have effectively 0.0014ohms resistance. 600A @ 0.0014ohm = 504W. Make it 20 mosfets and you're down to .0007ohms and 254 watts. Make it 100 mosfets and you're down to 50W!!! hahahaha!!!
Delay is critical. If you don't delay, you'd have your (say...) 20mosfets and 20 flyback mosfets making a total path resistance of 0.0014 ohms across 144v and now you're burning a lot of heat across this path... 14MW
I'll post more when I get more details or a good site to read.
