And ( a thought )

Deous : how do you expect to heat a ceramic with induction heating? - they're insulators.......

I just came back with update:
Replacing that mosfets in series with triac works perfect.
Circuit needs ac cap though - oven also flashes sometimes at different frequencies
All works perfect because triac requires really small voltage - 0.6-0.9V to switch on

Hi,
Good to hear.

Can you please post a copy of your new circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Thanks.. Tom.. :)
Everything runs on smoke, let the smoke out, it stops running....

It is the same picture as posted one in this thread. Additionally I found out an easy way how to generate a PWM signal using ESP32 that can be adjusted from 1Hz to 10MHz ))
It is perfect to control all kinds of devices. Posted code on other forum

Sorry this is what you posted? ? ?

PLEASE a hand drawn complete circuit diagram please, to help complete this thead for anybody looking for solution to similar problem they may have.
Thanks.. Tom.. :)
