FUELLESS CAR PROTOTYPE by ISMAEL MOTOR

Hi tinselK
take away those mosfets, and the circuit is a simple and normal induced-by-rotormagnets generator-coil circuit that fills up a DC cap after being rectified....you have to have "something" to be shorting at peaks, and that is the induced-power you get from the magnet sweeping by the coils in this particular circuit....what this peak coil shortin cirucit does tha tis good, is it fills up those caps much higher in voltage, and much faster than the "normal" circuit.
To spin the rotor with magnets that sweep past the coils, you can have any sort of motor, or drive coils built into the generator it doesnt matter that is whole other subject how the rotor will spin - do it however you want to...
This circuit is meant to show the circuit how to short some genrator coils at the peak period and fill up caps and that is it....it doesnt show how to spin the rotor, it doesnt show how to eventually unload caps to load either...for that the caps should be disconnected from the coils, whenever the caps do hit the resistive load in their discharge - this is called a  two-stage output circuit..

You can do the shorting on a transformer too, no rotor. Ill be testing it shortly...

Hi Kehyo
yes why not -use that "dual 4047" circuit by Ron shown up above to sense the peaks if you want....keep that pulse width very narrow so you dont get extra draw from the shorting events....if 60hz as an example, try to get pulse widht less than 1/2 millisecond, and time it right at the peak too - - the peak is sort of a teeter-totter point, things can go either way right there, plus this is maximum voltage too, so this is place to short the coil/phase at....
what Ismael does is create the ringing from the short, then he shorts the ring-peaks too!...If you can do that you will be in fat city...that is purpose of that dual-4047 circuit, with the chopping feature using the 3rd pot...

Hi Conehead.
As I said before I plan to use Arduino to generate the pulse, then I will measure on the scope the BEMF response.
I will know then, how long I have wait to make the shorting. Really easy to implement. I am winding some heavy ferrite cores now. I'll let you know how it goes.
I only recently have bought 100 supercaps needed hence the delay. $$$ :/

Hi Keyho and everyone
Here is drawing Ismael made for the EVGRAY yahoo group over a year ago - he is showing the wave-form you get when you pass a magnet by a generator coil, and then short it at the peak to make X3 power - which is good thing,  .... and then also in comparison,  he shows the CAP DISCHARGE DC-impulse trick to his MEG, where he first SATURATES the coil, then smacks it with 5 very quick shorts and he says there is 10,000 times power increase if you get it right......
he says that with magnet-generated waveform you dont get more power with additional shorts - since "no magnetic field" he explains...
Not sure what he means here exactly, but I assume the magnet-induced wave form is RECEEDING after the single peak-short, as shown in his drawing, so no way would it be saturated anymore.... but dont know for sure about that being the point he is trying to make.....
So he seems to say in this drawing and explanation, that its during the saturation-period, where you want to do the multiple shorts....anyways maybe this can be implemented in your BEMF sensing transformere aquino-controlled circuit Kehyo, maybe not...
so I will assume he is  saying that you saturate first, and after and during saturation is when you short the coil - and do it multiple times too.....I dont know why a very strong magnet wont have abiltiy to saturate a coil -  maybe you need a core to saturate???  (not sure)
if all you need is proper core, for magnet-induced generator coils,  you simply would want to do mulitple shorts halfway up the ascension of the sinewave and stopping the shorting-events at the peak is what I see but like I keep saying, not sure...... here is the drawing and explanation by Ismael -  maybe this will  ring a bell for someone:
