Anyway, trafo setup used here is better because it does not use input power at all even when load is taken.

Could you please provide the best video link demonstrating this claim?

Maybe of topic here, but this setup seems to be worth trying:


Plasma Ignition - Water Sparkplug Circuit by Peter Lindemann

Even though Peter does claim OU, it's obviously raising the output voltage at the sparc gap . The sparc gap itself is a small capacitor. The Output Energy to the cap is squared to the voltage.
Put another diode or fwbr in series with a HV-Cap instead of the sparc gap. Now you can calculate In and Output Energy. I don't have a clue why putting the HV diode from LV+ to HV+ on the ignition coil has this effect. But experiments of tiger2007 with triodes to use an avalanche effect are similar to this.

Peters setup would have a benefit on all electrolyzers.

When there is half wave discharge and you provide diode to short BEMF rising then there are additional processes are going on in coil. First it will make half-wave resonant oscillation then voltage amplitude rises to maximum and there you get better sparks...
This phenomenon is not used much and in case if you make circuit like this, it should start saving energy for transformers when using DC half-wave oscillators. Additionaly when there is capacitor charge/discharge there is explosive energy involved.

Sorry I don't have camera to make any videos/pictures. If you have gear to do high frequency tests then you can make the video if it does not work. It will not take much time to wind 11 and 140 turns around ferrite and connect them as shown. This will stepup the voltage so you can drive it using 5 volts and get for example 220 volts at load. The number of turns in the shorter coil is determined by the drive frequency and permeability of the core, enough turns that no power gets through when using just this one coil. I think tuned parallel cap would work also when placed next to shorter coil, but haven't tested. Worth a try anyway.

At the moment I am trying to figure out why watt meter shows inconsistent readings compared to testing directly using power from grid. I think I need to make tuned tank circuit in trafo 1 and then connect second trafo using two coils, the original setup. I try to drive first trafo using square pulses, bifilar primary coil connected from end. This should raise the resonant frequency higher and tank circuit should provide longer lasting ring because coil is bifilar. I check if diodes have any effect, most likely one is needed so that tank rings the coil and not the driver. When resonance is found, I change on/off ratio.

If this two trafo test is successful, then I would try using lower permeability core in first trafo and higher in second. This should provide feedback to source which is higher than the drive and voltage would accumulate in the tank cap as the feedback is in phase with source. GDT parallel to cap provide overload protection in first trafo and thing should then run by itself, or provide better output. I have a tiny ferrite which I could perhaps use for testing, got it from broken printer. There is maybe not enough room for windings though.

Testing might take some time, this is why I put here in advance what I am going to test, maybe someone could try the same things too.

I had some tests on your supposed project. The reviews are in your favour as efficiency of transformer seemed to be 99%. I'll try to highlight your idea in regional electrical institutes so as to develop it in more efficient way.
