Operational demonstration and short description of the operation of my very simple full H-Bridge Royer oscillator which is driving an induction heating coil.

It delivers a 10-12vac 200Khz voltage to the 8-turn output coil, which forms a tuned tank circuit with the capacitors

Extra brownie points if you notice that I forgot to finish drawing three of the FETs in the one schematic in the video.

Below:Yellow and Blue are the voltage on each side of the tank circuit. The red is the difference between them.
You can see that the tank circuit is switched at zero voltage, so the fets run very cool.
