What he didn't said is that to low the losses you can use active rectifiers using mosfets. But its very cool to know that 1n4007 after 15khz don't completely rectify the current. This make me think that my experiment of the resonance with the series diodes where i used maybe up to 20 1n4007 paralleled together cause they use to get really hot. It worked up to 100khz on the experiment i still got electrolysis happening. However at lower frequencies the current was greater up to 20 amps recirculating at 500 volts..
