Yeah, powered it up, looks to work pretty good. No complaints about kicking it up to 200V? How about the full 320VDC? How about the full 50A? ;-)

IGBTs are pretty fast

A guy I worked with once did a somewhat silly thing. His sidekick had spent 6 months developing a monstrous (almost 2'x2'), wire-wrapped vector controller for driving an induction motor. it was wired into a
2.2kW drive in the test lab, in a rather ungainly manner. S came in on the weekend, saw it was all hooked up and thought he'd give it a whirl. Alas in a moment of clumsiness he knocked some wires off the bench which got caught in the spinning shaft of the test set, which proceeded to rip the controller of the bench and tear most of the wires off. oops.then there was the girl who dropped a scope probe into a 70kW drive, and shorted the national grd thru our 1yr old HP33xxx AWG. *BANG*
the awg was basically a single 4-layer PCB, with earth running thru the middle of the PCB. it had a 5mm thick 50mm round delaminated portion where the earth track vaporised, and cost us IIRC $500 less than a new instrument to repair it.
