Shorting coil gives back more power

Hi Gyula and all

Thanks for advice and i am looking for the best fet.

But more important at this point is to make some order in the research.

Because the general setup is really interesting and after 3 days of full scrumble upon i begin to see a way to go on.

So my aim is to replicate exactly what ROMERO UK did in his video, where he can light 70 LED very brightrly with only one REED and one 47 uf 250 volt cap  and this WITHOUT LOOSING RPM.

So  far from today, is that i replicated this and finally i could get my (all that i have at disposal for the moment)  13 led IN SERIE to very good lighting.
But the price for this is a slight increase in current draw on the motor.

So the aim of the AC cap (as per Konead) is to suppreseed the lugging of Mister Lenz. So i think that, the MATCHING  of the coil + core + cap + magnet rotorspeed  is at atmost importance.

And for today  when the rotor is spinning (without the shorting the coil ) it gives 3 volts after the FWBR  (and the 13 leds in serie does of course even get a sign of light) and  as soon as i connect the shorting circuit with the 2 mosfet , the same led ramp light very happily and the the voltage is about 36 volts.

Very interesting

i will make some thinking on this subject to prepare a video

good luck at all

Thanks for sharing your experiments Very interesting

Woopy, you have good nose

With reasonable confidence I can say that to access this "effect" one needs very sharp gradients and/or exiting coil at its resonance frequency,

Easiest way to hit resonant frequency is to use spark gap, reed in this application works as spark gap. Thats why people have seen good results with reed and virtually nothing with transistors etc. Ordinary solid state components when driven in ordinary way are slow and transparent for HF and just do not work in this application.

For those who are trying to make solid state version, good choice would be russian "kacher" type circuit. There solid state components are "shockwave" driven and give desired effects. (NB! Kacher can and will affect your health, strong RF emission! NB!)

I dont see how one can easily combine very sharp gradients at exactly right frequency with rotary version and transistors etc. So I would bet on heavy duty reed or some other component exibiting wide spectrum sharp gradient "white noise" emission (and physical breaking of circuit).

Also series AC cap is a must. When there is AC cap in series, Ohm and Kirchhoff do not apply. And thats already half-done deal.

Also forget about directly measuring amps out of this contraption! This power is only good for driving not resistive loads (or charging acid batteries)! To use it for resistive load you must first transform it.

And as always, trust no one, follow your instincts, progress only after replicating basic effects
