The bifilar pancake coil at its resonant frequency

[nelsonrochaa]

Hi ppl ,
I share the circuit diagram used to made my tests with pancake bifilar coil like i show in the videos i made .
Hope interested people could duplicate them . Ivo like we talk , this is my contribution.

Thanks For your great contribution to the community Neslon!
I labeled the components for easy reference.

I will be working at this on my workbench on  the open-source-energy.org forum.

ps: It says, "Floating ground" between C3 and the pulse signal

First thoughts:

C1 is parallel over the circuit, looks like a pure DC, stabilizer, being discharged over the L2 coil by the pulsing mosfet.

L2 looks like an bifilar coil, with a center tap. C5 is parallel over 1 winding of the bifilar coil (could make it resonant?)

This (pulsed mosfet) produces negative inductive spikes on the high side (and middle tap) of L2.

The negative inductive spikes (back EMF) are charging the capacitors C3 and C4 (and c5?)

C3 is series connected with bifilar coil L1 and C1.
The inductive spike will bring these series connected parts into resonance (?), producing an AC signal , So the Foating ground is fluctuating indeed.

the pulse signal, is created by the oscillations .

It is not clear if L1 and L2 are coupled, I guess not.

D2 and D3 pass the negative cycle of the resonant L1 coil, to L2 Timing seems essential.

C1 and C2 pass AC block DC, so the mosfet sees DC with an AC signal on it (?)

So far, my first insights, This has been pure guessing.

Hi Evo,
Sorry i forget to mention the secondary coil L3, which is a pancake coil as well, to stack in the order L1 L2 L3 .

cheers

Thanks Nelson 

that makes a lot more sense.

I guess this also means the pulse diving the gate of the mosfet is generated by an pulse transformer, driven by an external pulse
