Chinese Oscillator and MOS FET Driver, Hardware experiment

You need a tuner!

Thanks, i'll think more about it. The other solution is to make a peak shorting across the 28T to raise its voltage as much as i can. For now i am just trying to go as per Chineese circuit. Even if there is a fat chance that the Chineese hides something in his contraption like a HV converter module. It is not possible with the given circuit to reach 200V across a 2KW induction cook like the Chineese shows.

You need a tuner cap! There's an 8000 volt .022uf capacitor in the schematic.

Exactly. This is an indication that we have HV running inside his tank circuit. I can't reach a higher than 400V pk-pk. I also use an input choke to my ZVS driver. The Chineese doesn't.

The "Gimmick" is that the designer matched a household wire coil to a resonant capacitor and tuner all in correct proportion to deliver a very high "Q"!

The high 8000 voltage rating does not prevent the trimmer from working in the lower voltage ranges; However, when tuning for "Q", these voltages develop between the capacitor plates. The trimmer is nothing like an ordinary butterfly capacitor.


The coil turns and primary capacitor are matched sufficiently to produce a basic resonance that the fine tuner capacitor can operate on. Ordinary variable capacitors will burn out too soon.

My dad learned a lot from you.
Even small Yoke-transformers have little effect on the output.
Note please.

   Jeg:   Do you guys have a picture or video of what you are trying to replicate? Or, your version of it?
   Is this circuit being discussed here supposed to be  OU, or self runner?
