There is no load reactance. It's all resistive. The capacitor across the line is fairly small, but simply modifying the PWM controller a bit so that it has an overall slight inductance (or putting the current feedback before the capacitor) it's cancelled. The choke in the feed line isn't to cancel the input capacitance, but to stop the 1Mhz RF getting back to the generator. Mr Edison was the first to find that that was a bad idea. > Ian ... it's a blast from the past, mantra ... "50Amp, 40V, 150Vac" ... I'm > quizzical here, mmmm!. That's the old Bgas ECE spec'.
