Kapanadze Cousin - DALLY FREE ENERGY

[Jeg]

Itsu and all.
This is how it looks like when you return back a good portion of energy. Yellow is across my input capacitor. Purple is at the output.

Hi Jeg. What is the approximate efficiency you are seeing?
(ratio of approx. output power to measured input power?)

[Jeg]

Hi Void.
I worked with a very inefficient transformer with huge flux leakage. Perhaps you have seen it at Piere's thread. So any approximation would be wrong.

Hi Jeg, It seems to me you should be able to at least roughly approximate the efficiency without too much issue, but OK.

I use a pulse overlapping method using six primaries. Three for the positive and three for the negative cycle. Depending on the input frequency  for each of the switches, i control input current. Efficieny goes up as long as more currents pass through the primaries and it is normal as flux leaquage is high. I still didn't go to higher input currents than 2-3A. So in this specific waveform i attached efficienty is not more 40%
