Lenz free generator

Could you elaborate on this Ron. Does this mean you are pulsing the series connected strands, then coil shorting the other strands during the off mode of the series coil? That is, the short is 180 degrees relative to the pulse? Have you tried simultaneous pulsing of the series connected strands, with the other strands shorted during the pulse, with both mosfets open after the pulse?

Trying to understand your sequencing of coil pulsing and shorting, and which coils are doing what.
Cheers Ron

Sorry Hoptoad, I was having a seniors moment there!  The two pulses are nearly simultaneous. What I was aiming for was the shorting pulse to be shorter than the power pulse. To achieve that I used the propagation delay of the four sections of a CD4011 which delays the power pulse by say 180 uS. But I was using mosfets so damned body diode gets into the act. Not a fair test, just a. "what I was doing didn't work", test.


Edit: However, with no coil shorting, the cap dump circuit works great. I was wondering if it was working at all at 7.5 mS dump pulse but that was with a nearly charged battery --- with a battery from storage at 10 volts,  the pulse length went to 42 mS so quite happy.

What might happen if the primary had a low inductance\resistance and just before the peak voltage was reached a second coil was then shorted or connected to an empty cap?

I see the primary having a small current suddenly bursting a high current pulse due to the transformer action with the second coil, the flux field is charge carrier motion,, so the flux field would jump up from the,,,, lets just call it an impulse current hit,,  now provide some form of interactive resistance to the collapse of the now large flux field, that sounds to me like an inductive interaction.

Just thinking in public,,

Same here.. I think we are still miles from where erfinder is at this time

Ron,

I went  back and tried that circuit again with mosfets and it did NOT work.  Apparently you are right about the internal diode causing problems with this circuit.  If you use a couple of 2n3055 transistors or something similar you should get the same results I got in the video.  And I did not have any delay between the switching of the transistors.  They both turned on and off together.  Hope this helps some.

Thanks Carroll, I will try again next week.

Thanks, that answers my query. And don't worry about having a seniors moment. I have them too!
I deal with people whose seniors moment lasts all day. When your moments become minutes, start worrying.

Cheers
