Hi JR,

Way ahead of you on the analog inputs, I've got 3 proportional inputs, for throttle, regen, and an extra that could be used to control magnetizing current, which would basically act like a continuously variable gearshift. All the inputs will accept either a pot or 0-5V.

I have some preliminary (incomplete) schematics, I post those later today. Catching problems earlier is always better. I think I've got all the major parts in, so it'll be a good reference for what's in the system.

I'm trying to fit everything (control, IGBTs, bus caps, current sensors) on 1 PCB to eliminate the hassle and reliability issues of to board interconnects. All the power would be carried by bus bars or wire, with the PCB used only to carry the capacitor current to the IGBT terminals. I've attached a quick sketch of the concept.

Regards,
David
