Kapanadze Cousin - DALLY FREE ENERGY

[Void]

As to where the extra energy is coming from. This has been partially explained by Tesla, and demonstrated by his electric car.
He mentioned that he ran it for a week, even at top speeds of 90mph. No batteries.
Yet, few believed him,  as well as to his ideas about the Aether, etz...

Hi Nick. I looked into that claim about the supposed Tesla self powering electric car a couple of years ago, and
it appears that this was just a story told back in the late sixties by some guy named 'Peter Savo' who claimed to
be a nephew of Tesla. Apparently Tesla never had any nephew named Peter Savo, and also apparently no actual evidence
has ever been found to back up this claim about the electric car. It would also appear also that Tesla never made
any mention about any such event as well. Seems to be just an unfounded story.

Here's one for you to consider while we are doing some thinking.
Two PWM's clocked at the same frequency with the second PWM running a slightly shorter cycle time.  The output of the XOR gives an interesting "breathing" effect; maybe a pumping effect.

Yes, and after some low-pass filtering at the output of the XOR gate, the difference in these two frequencies appears.

At first you may be inclined to think this has nothing to do with the Ruslan device.  Look again.  A similar effect is happening with the PLL as it tracks the resonant frequency.  You can't see it because you are not looking for it--wrong time scale.  Granted this PWM circuit is precise and going through an entire spectrum which I do not think the Ruslan device is doing, it's only partial.  Actually, the PLL circuit appears to allow the resonance to drift, then snap back when it finally synchronizes, so instead of a steady "breathing" effect, it's more like an inhale then a rapid exhale--similar to a long distance runner's breathing pattern.

Indeed the output of the loop filter tracks back&forth a little and the output of the VCO does the same.  This is akin to a slow FM.

Notice, when the RCD clamps are used, this is the current that is converted to heat
...and when the lossless clamps are used, this is the current that is returned to the supply input circuit.

Note, that the several % of increased efficiency is merely a side effect of the lossless-clamp circuit.  Its major purpose is to clamp any spikes above 2*V_CC and protect the MOSFETs from overvoltage.

Verpies, could you take just a moment and try to explain what the secondary on the transformer has to do in order for power to pass out that direction versus just cycling back via the loss-less clamp windings.  Impedance is the word that comes to mind, but I'm having a bit of a hard time wrapping my head around the concept.  I understand what they are doing in an open circuit condition, but I'm not clear how they function when you have something connected to the secondary with an impedance mismatch.

But this was Itsu's statement about a different core that had insufficient permeability for that driving frequency.  He calls it "toroid yoke" vs. "yoke yoke".
In his videos with the "yoke yoke" he measures mean input current.

If you ask him to compare the mean input current with the lossless clamps vs. the dissipative RCD clamps for the same output power in one video, I am 80% sure he will do it for you with the working "yoke yoke".

You can also ask him to place a current probe on the clamp diode to see how much mean current flows through it.

   Verpies:  Yes, I understand about the "that's it and that all",  but what I'm more concerned about is comparing the outputs of the two different yoke/grenade circuits, not the inputs, although that's also of interest.  But, how do their outputs compare?
However, I think that may be missing something...
Didn't Itsu mention that the toroid yoke with the clamp windings did NOT work out, as it triggers that over-amp protection circuit in the PS???  Any new solutions to that same issue?  Like winding the Tv yoke with the normal windings, but adding thinner clamp winding, also.  The 3 inch yoke may work for that purpose, but any of the smaller yokes may be too small for the extra windings.
  So, don't you think that a Tv yoke should be tested for the clamp circuit, as well?

Nick,

it seems you are confused about what tests i did.

I did make a TV-yoke (big one) loss-less clamp design and compared it to the (smaller) TV-yoke non loss-less setup i had.
The 24V input current from the battery during resonance is lower for sure, but i did not record that specifically, i just notice the input amp drawn to be less (about 1A less).


As i have slightly less turns on the 28 turn secondary (its only 26 turns) of the this loss-less clamp design TV-yoke, the output voltage on the Grenade after rectifying is somewhat lower (212V vs 220V DC).


I then made a loss-less clamp design setup using a T520-2 toroid (meant for 2-30MHz operations) but as verpies mentioned this one did not work due to
the low permeability of this toroid causing to much amps to be drawn for my 24V battery stack.
I will rewind this T520-2 toroid with much more primary windings (loss-less clamp design again) to see if that will fix the amp drawn problem.


For now i am still working on the big TV-yoke loss-less clamp design as it still gives me some oscillations at certain PWM drive frequencies, during resonance and
when waving/attaching some ceramic magnets to the yoke.
It probably is due to some oscillations in the MOSFET circuit and i am trying to pinpoint that.

I know it could be considered as off-topic, so please ignore my posts about that.




All,

i tried to measure 1 of my loss-less clamp TV-yoke primaries using the tracking generator/spectrum analyzer, but as it is new to me i could be doing it the wrong way.

The screenshot below shows what i believe to be the frequency response over a 100Mhz range (9KHz - 100MHz) of one of the primary coils.

The video showing how i did it is here: https://www.youtube.com/watch?v=j0a__W0nDEg&feature=youtu.be

I don't think it explains the oscillations in the life circuit when waving the magnets as i only see some subtle changes.
