Of course it works, several people built it before and published photos and videos. But now I did it on my own: a rather small induction heater. In the first photo I ran it with only 12V and at about 2.5A, but this was enough to bring a small nail to red heat. Some waveforms: At the gate of one of the MOSFETs: At the drain of one of the MOSFETs: And finally across the capacitor: ')
