Confirmation of OU devices and claims

[Void]

My capacitor is across the coils to create a resonant condition before the FWBR, I'm dumping from the FWBR back to the battery.
I can do a follow up tomorrow with your suggestions plus any others, if anyone is interested.

Hi Grum, Ok, that explains why your scope waveform was looking like that.
You can leave the cap across the coils if you want, but, I think to be like Bedini's 1984
generator setup you need another cap across the DC output of the bridge rectifier,
and the commutator switch goes between this charge cap and the battery. This charging
cap will charge up during the period when the motor is powered on, and then discharge
with a sharp current pulse into the battery when the motor power is off. This way the charge cap is storing
up energy from all the energizer pulses during the cap charge up period when the motor is powered.

P.S. If your generator RPM at top speed is around 1850 RPM, then if I didn't make a calculation error that
means each full rotation takes about 32ms. Half of that is available for the cap charge time, so about
16ms, which depending on the capacitance value of your charge cap may or may not be enough time
to charge up the cap to a voltage of at least 15V or so. The higher the total capacitance you want to charge up,
the more time it will take, so to charge up a large sized cap or cap bank you may need to gear down the
rotational speed of the commutator. If you have some different capacitance values available, if you like you can
maybe try different values of capacitance to see what max value of capacitance your generator is able to charge up
to at least 15V in 16ms.

All the best...

HI Grum,

I agree with void.  You need another cap after the bridge so it can charge up while the motor is running powered on.  If you were to take the time to look at the thread on the Energetic forum by Bizzy he claimed he had this system working.  He first powered the motor up to speed by bypassing the commutator.  That gave the caps time to charge up also.  He had a large collection of caps connected in parallel after his bridges.  Then when the motor was up to speed he switched in the commutator and let the caps keep the battery charged up from the pulses from the caps.  He claimed his system was large enough that he could use some of the excess energy in the caps to power an inverter to power some of his house.

Your build looks great.  Thanks for sharing.

Great engineering skills. Well done Grum! For sure i would try an operation without any diodes. Keep it up and thank you for sharing!


ps. Does your energizer coils open-circuit when cap discharges to the battery?

Hello All.

Many thanks for your encouragement and compliments, it's appreciated.

My scope is telling me that the open circuit AC voltage is just under 100 V pp.

Lots of possibilities to investigate still, in fact I haven't tried adjusting the position of the commutator with respect to the magnets yet!

Pretty sure there's more to come.

Cheers Graham.
