Induction heater v. 2.1: copper melting

Your fan is noisy, and you seem to need better smoothing of your dc bus.

@TheElectricnoob I don't need smoothing. I don't use smoothing specially to improve power factor.

@NickSviblovsky Looks like you use a series resonant tank circuit, then you have unity power factor at resonance.

That is the beauty of series resonant, at resonance, power factor = 1 while parallel resonant PF is like 0.3

[NickSviblovsky]

@TheElectricnoob Yes. That's right.
