@wattsup,

My drawing is a direct copy from his videos.

@chrisC,

You are correct.

Thanks Groundloop. And I think Tommey is correct. Here's my understanding from the latest 2 videos.

The battery & PWM draws 116ma and I assume a duty cycle of 50% at 12V. This is an average power of 0.116x12x0.5=0.7W.
The unloaded capacitor voltage spiked at 115V but settled at 24V useful voltage and runs the motor at 68ma (assuming it's all DC) giving a power at 1.63W . That's proof of O.U!

Correct me if I am wrong.

cheers
chrisC

Pulse generator, 30% load on bach EMF coil.
http://www.youtube.com/watch?v=GzS7MN_u-54&feature=channel_page

Quote from Tommey
At 30% of pwm pulse at 10khz the output of back EMF is greater then pwm set to a 50% pulse.
At higher amps at 30%, the increase of back emf of current.

@chrisC,

Based on the measurement in his videos, yes, you are correct.

I have modified my test circuit with a hexfet (IRF840) instead of a regular transistor (2N3055).
It seems that I can not loop the output directly back to the input because the internal resistance
of the lead acid battery is so low that it is a short circuit for the captured back emf.

So if we want to do a full looped back test circuit then we will need a impedance match at the output
and to the input.

Regards,
Groundloop.

@all

My question is:

Is he using an in circuit PWM ? Or He is using an outside PWM ?
If the PWM is from the outside then there is not OU.

Thanks. As Tommy pointed out, at 30% duty cycle, the OU efficiency is even better!
Hence, giving back the % that will allow the loop to recharge the batteries will indeed make it perpetual and still do more than useful work!

I assume we can capacitively couple back some of the back emf charge. It can be done since Tommey now has proved his point.

The PWM is run from the same 12V in the system. That's where the 168 ma is measured. What is the point otherwise?

Thank you @chrisc

Does you or anyone has the circuit for the whole thing with the PWM included?

Conceptually, it's very simple. 4 fast diodes of the 4007 type, a single primary of a coil transformer, fast drivers for the 3055 power transistor and large caps rated 200V to collect the back emf. The PWM is probably any single chip PWM capable of 10K.

why no one discovered this back emf captured to a capacitor and filtered for useful work beats me?

The thing is that we are looking for the circuit that has a PWM and is working in order to replicate it. The one kindly posted by @groundloop here: http://www.overunity.com/index.php?topic=7241.msg174681#msg174681 does not have the PWM circuit or chip number included.

With efficiency of at least 400% at 30% duty cycle will absorb any kind of PWM chip you're likely to find. You can even use a 555 timer and some external components and that will still be OK.

Thank you @chrisc !

I am begining to think that it seems that nobody has replicated it yet and have gotten the mentioned OU.

With OU I mean that the circuit gets its battery charged from itself. I would be happy with the battery just not discharging.

Thank you @powercat !

I will wait a little bit for confirmation from other members that the circuit works and I will send for the needed parts from my next part time job money.

The optimal pulse width is 38.2% (Fibo) for this setup. 

This is why Tommy is seeing 30% better then 50% but he don't know the math behind it.

The system gain is (1.618 * Q of the coil)- System losses.

This is standard book values no magic etheric space dust here. All was shown by JML labs experiments, ARK Research and Bordland labs for longitudinal gain more then 10 years ago and elsewhere its all well published.

So back EMF or forward gain is a stochastic energy gain 1.618 over isotropic minus losses its OU,  if he can make losses small enough. Load must match perfect resonance to o/p. If you are charging batteries then battery acts as large capacitor. Will change system from OU to non OU states as it charges and discharges and creates resonance changes that must be addressed.

OU is real not dreams you need to know how to find it and use it. Above equations work for Newman, Bedini, coil bangers, and many other coil spiking systems and motors they all work the same on basic book values RF.  and 99.99% of people have no idea what it is even when they build it.

If you want more single stage OU power gain then Q is the easiest thing that can be addressed. Bigger coils, lower losses etc and more advanced use negative entropy looping and multi phase feedback aka TPU etc. So for three phase system its (1.73 * 1.618 * Q) Notice how much gain we have now. This is why RotoVerter system is so efficient. A 7.5 Horse Power 100lb motor will turn at 2800 rpm on just 10 to 15 watts.

Looping is an entire new problem due to impeadance matching networks are usually lossy and kill the last bit of OU.  That is why easier to show i/p power to separate o/p. Not as simple as putting a wire from out to in.
