That's a good point, Mike. Does the fact that i'm sending a variable PWM signal make it so the transformer is actually converting a 16khz source, thereby making it efficient? Or would i be running into the same kind of current "filtering" due to back emf from the motor working its way back through the transformer?
Maybe i should jump back on my "1kw audio amplifier to drive a motor from 12v" concept... i now have a low powered 120v AC motor at home to play with... and an audio amp (but only 400Wrms). Those audio amp people have been doing voltage step-up and signal amplification for years... i'm sure they're good at it.
