Hi dog one
Ok fwbr a.c. legs across coil
Dc side of fwbr into cap ( such as big caps already pre charged) as in DZ gen
Now two approaches:
Have switch on one of the a.c. legs of fwbr that  connects the recovery to caps
Time this switch to have delay time approx 5 degrees retarded
Works like an echo..i call this "active"recovery circuit
"passive" if no switch.on a.c. leg of fwbr.
Delay time longer if low frequency
delay time less if higher frequency...tune delay time to system as it operates.
Power in recovery output now huge as no reflection back to primary plus I will guess actual backemf forces coheree with flyback spikes energy all comes out same direction in dc from fwbr this the lamebrain theory but this really works.
2nd approach is shorting induced or pulsed inductor at peak...
If pulsed this means close switch that shorts out  coil just before saturation point.
If induced such as sweeping magnet past coil then close switch to short inductor very briefly  at sinewave peak period.
Have fwbr a.c. legs across inductor and dc side to cap only
Discharge cap by itself to load for power....
I suspect DZ generator in its crawling rotation of A AB B sort of
Coil energizing sequence perhaps causes A peak shorting type of event when one coil moves "over" the adjacent coil if polarities reversed maybe does not need to be reversed and get effect from constant movement and two coils being energized at once and remember power in magnets is at the edges and  so leading edge has reversed polarity as to trailing edge same with electromagnets maybe overlap of leading "top" edge over trailing "bottom" edge  of rotation causes brief coil shorting event if rotation speed and iming is right and so then voltage in super caps rockets up like crazy...maybe backemf inherent forces manifest in coherence too don't know.
Murder of Eugene Mallove vonvinced me 15 years ago  dark forces will kill to protect their power with no problem to them to do so
they don't care they don't have to.

With parametric resonance and ways to make nuclear reactor from the core while there is simple alternator function going on... That is what I am calling overthinking.
Guys, again, grab magnet, move over coil , see what parameters change is creating current on wire. Then make same with coils. Simplicity have to be here not overcomplication.

Cheers!

Hi
I am in the process of building my switches and i just received my main switching components (IGBTs).
https://www.infineon.com/dgdl/irg4pc50u.pdf?fileId=5546d462533600a401535644832d22f2

Datasheet mentions that this IGBT is optimized for high operating frequencies 8-40 kHz in hard switching, >200 kHz in resonant mode.
Does that mean that i will have problems if i operate it at lower frequencies in the order of 100-1000Hz?

No. Lower frenquency=less loses.

Thanks Menof
Good to see you
