In attempting to do 2 things at once (step up voltage AND modulate power), I achieved nothing more than a shitty looking waveform and some noise at the end of my circuit. Therefore, I am considering doing it in 2 stages. First step up with a simple 50-50 square wave across my transformer and then after rectifying I can PWM that into the final wave and it should look much better than the way I was trying to do it. However this create a new problem in that now I need a high voltage H-Bridge, whereas before I was doing everything a low voltage one.
I have found a couple of reference boards that seem to do this but very very spotty results and lacking the current specs I'm after.
So basically I'm looking for this but with a 200+V rating and 2-3amps:
I need an H-bridge, motor driver or whatever equivalent that can handle 200V or more source voltage and also >2 amps, preferably 2.5 or 3A. Does anybody already know of such an IC or board? The more integrated, the better, so I don't have to run into a dozen problems just getting it to work. I've checked sites like Pololu already and they don't have anything in the 200V regime that I could find. Thanks.
