Kapanadze Cousin - DALLY FREE ENERGY

To what frequency L2 should be tuned ( resonant):
1) to the inverter frequency?
2) to the nanopulser frequency?

I have tuned L2 to the inverter frequency, about 58 to 59 KHz, but on Dally's schematic and from the coil data, resonant frequency on L2 appears to be from 4 to 6 KHz, although in my calculations I did not take into account the mutual inductance neither the effect of the other coils. In my implementation, I found out that L2 inductance reduces a lot from the stand alone measurement. I can get about 23W out, in a 12V car lamp, and input power is about 40.5W. The interesting fact is that, with no load (lamp not connected), power input increases to 42.5W.



Any clues?

Had anybody have the opportunity to analyze this post?

Or could it that the Russian KP1554 or KP1553 are more powerfull, and are able to fully open the BJT?

Yes!
Russian parts are often built like russian tanks.

Were those boards on the photo made/used by Dally ?
Do you have the .LAY files of those boards?  It would be nice to have them to make printed circuit boards (PCB)

Hi verpies,
here are the original boards Dalli who gave on his blog.

I think that with that 1.5μF cap in parallel it will be in the kHz range, but I was not sure, hence I was not replying.

That was my source of the PCB images in this post.
