>Are you switching mains voltage into a resonant primary side?
That's the plan. Annoyingly I have no idea how to characterize the resonant circuit, so I'm just copying what other people have built. The work coil is "a few mH" but maybe it changes when you add metal, so I've got a circuit for controlling the drive frequency by the phase of the tank voltage. The tank capacitance is "whatever it takes so that you resonate at your target frequency" and "maybe 300A" so I anticipate adding or removing capacitors empirically. And even the target frequency is just enough for a "gentle stirring action"
So basically the numbers are all made up and nothing matters, throw 12 kW at a thing and it will heat up no matter what you do. As far as I can tell all the hobbyists just tinker until they get it right
