Hi Ole,

this is now high frequency with square wave signals or control as I have seen on the video.

This is difficult to compare with my transformer. The voltage remains in the clean sine wave, only the current becomes more sharpened the higher the capacity becomes and the resonance remains stable, of course the iron core heats up at high capacity.

I have a real FR transformer with a magnetic voltage stabilizer and also drives clean sine voltage.

The only thing that I noticed is that I can build a small spark gap with a ground cable on the iron core of the resonant transformer, if you hold the wire just to the laminate, there is a permanent little blue spark. When this spark rolls over, you can see these strong spikes on the oscilloscope, but only as a spark gap, I firmly connect the earth to the core, nothing happens.

"Ferroresonance as a moving target" How to understand that.

If the core is saturated, the current increases, like an air coil so you have to limit the capacity shortly before this transition?!?

Maybe the result looks quite different if I would fire the transformer with sharp square pulses!?!

That's why I wanted to build this Pushpull drive, since the winding is designed bifilar I can operate the transformer in push-pull mode.
