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*VCC 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.

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.
In an ideal transformer the coupling coefficient between the primary and secondary is at unity, and the voltages and currents in them are determined by the Lenz law and turn ratio. The secondary acts as a perfect voltage source without the intrinsic self-inductance (because the self-inductance is consumed by the mutual inductance).
A reactive circuit (e.g. a cap) connected to the secondary will store the energy delivered by the secondary and feed it back at a later time.  At that time, the secondary will act as a primary and the turn-ratio will act in reverse, so the the back-transformed voltage will not be any higher than the voltage appearing originally at the primary primary and the clamps there will not activate.

The clamps (RCD or lossless) can activate only when the voltage across the primary exceeds 2*VCC.  So for this to happen, the primary leakage inductance has to rebel or the energy that is reflected back by some reactive component at the secondary, has to be greater that the energy supplied at the primary. 
In case of RCD clamps/snubbers such energy would be just dissipated as heat.  In case of the non-dissipative clamps - it would be recycled to the input.

I'd like to point out that the clamping performance of an ideal RCD clamp/snubber is the same as the clamping performance of a non-dissipative clamp/snubber.  The difference is only how they get rid of the "unwanted energy". 
In practice real non-dissipative clamps clamp closer to the 2*VCC level than real RCD clamps, which do not track the VCC at all, because they depend on fixed-voltage components such as fixed-voltage Zeners, MOVs or TVS diode, etc... 
Unless you are lucky, it is very hard to set the RCD clamping level exectly to 2*VCC, so most designers just settle for any clamping voltage that is above that but lower than the MOSFETs maximum drain-to-source blocking voltage, that these clamps are designed to protect.

All the desired transformer energy transfer and MOSFET switching happens below the 2*VCC threshold.  If any oscillations or ringing happen below this threshold, the clamps will not activate (as if they did not exist).  If they had activated below this threshold, then they would be clamping/fighting the waveform generated by the MOSFETs and something would burn up.

I don't know. I am still on the yoke circuit. Specifically it interest me why it produces these high frequency components wen fed with a waveform that does not contain any energy at these frequencies.  I need to understand that so my upcoming PLL circuit will not lock onto the wrong frequency.
Of course I realize that for any test of the input current to be meaningful, the output must be the same.

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???
Nothing worked with the "toroid yoke" because it had insufficient inductance.  When inductance is too low then current in the primary winding rises too fast and trips the 10A limiter.  That had nothing to do with the clamps.

Any new solutions to that same issue?  Like winding the Tv yoke with the normal windings, but adding thinner clamp winding, also. 
It's possible.  The clamp winding can be thinner because current flows through it only when a spike above 2*VCC appears.  At other times it just sits the idly as if it was not there ...so the average current through it is quite low.

So, don't you think that a TV yoke should be tested for the clamp circuit, as well?
I do, and I believe that's what Itsu did initially before he tried the low permeability "toroid yoke".

I have not watched or analyzed your methodology yet, but the most common thing that can go wrong with these measurement is distortion of the tracking generator's output due to impedance mismatches and reflections.  The solution is to put a circulator or attenuator at the generator's output in order to isolate it from a misbehaving load.
Not normalizing the spectrum analyzer when the output cables are connected directly to the input cables (without the DUT), is another common rookie mistake (if an isolating attenuator is used - it should remain in place and participate in the normalization).

Applying DC to other transformer windings through a good choke, is another test that can be performed to see how the transformer's core responds at various magnetic fluxes.  Flux generated by such DC, has a different direction than the flux from external permanent magnets.

@All
Notice, how complex the frequency response of a simple yoke transformer is.
I expect the frequency response of the grenade coil to be even more complicated.

It is no wonder that it is so difficult to replicate with such unknown complexities.

If one of the "successful" Russian friends gave us a plots like this of their yoke and grenade - we could replicate this device in weeks.

hi Void,

I am glad you have dug deep into Tesla history and remove confusion base on what people expect or would like to hear.

I don't recall any part of Tesla history there was "Overunity" mentioned.It is just people whom took "Tesla huge Transmitter" and thought it was overunity .

The fact remains unchanged "Tesla plan was to transmit energy for free" to the people but at the cost of  powering up the Tesla Transmitter which was sponsored by JP Morgan.

It was Tariel Kapanadze that inspired people like Akula,Vasmus and etc.

Hi@all
This is my lossless layout. Still didn't find time to fix it. Some degree of high voltage spike is reduced when I touch my diode's heat sink. I'll try to make a drawing on how my coils are connected in case you see something unusual.  https://www.youtube.com/watch?v=zvJnEqeZAYo

   Itsu:
  Thanks for the clarification concerning the tests of both the big toroid as well as the Tv yoke.
 My main concern was what effect the clamp has on the output levels, compared to the normal Tv yoke.   
I'll look at your last video now. 

    Void & magpwr:
    Thanks for your opinions.
    However, you are basing your evaluation on a false story, and not the real one.
    The Pierse Arrow was electrified back in 1935. The false story from 1960s was a different thing.
    I had heard the story and comments about the cousin that never existed, but, that was many years after the fact, and has nothing to do with the real deal.
    I've also heard the other version, Tesla's version about the car, although I don't remember were I heard it, now. Possibly taken from Tesla's notes. As it was not in third person dialog.  But, That real deal is still a well hidden secret, and will probably stay that way for as long as possible.
   
   I think that the most important point is that he did make this car conversion, which he had witnessed while he ran and tested it for one week, while he tried to convince any interested people of his ideas, but had no takers on it, at the time. 
   This is no small secret.  And is a secret, still.

   Here is a model of what the car may have looked like.  The box on the seat was activated by Tesla holding the two short metal rods in both hands. Antenna was mounted on the back bumper.
    I have never heard of Tesla not telling the truth, as he saw it.
    Believe what you will...

Hi Jeg,

When using the old style setup with the snubbers looked great, only the big spike is still the problem.
The only way i think to get that solved is to short it out with a varistor and/or TVS.


Concerning the loss-less clamp design, i have no idea why it still shows these drain peaks.
I do know that the voltage you measure on the electrolytic caps (a solid 24V DC) is correct as i have measured the same.

I tried to follow your yokes winding layout and i understand that the black leads are the primaries, the red leads the return clamp leads.
From the 7 connections on the elco board, you have the yellow/green as the common "return" to +24V supply from the dual schottky diode i think.

So except for the long wires (especially the gate wires) i don't see anything obviously wrong with your setup.

Hi Itsu. They look good and also the high voltage peak is below my mosfets's avalanche point. But I can't rest on this when I know that it can be done with less wasted power.

I thought that Verpies meant this voltage to be 48v. But may be I am wrong.

Seven connections. The middle one goes to the middle of my 3pins double schottky diode. This yellow green cable is one of my drains.
Yes, black cable is my main primaries, and red is recycling the power. Just as the colors which appear to be in all of the the lossless clamp circuits published here by Verpies.

As for double schottky diode, I used an MBR10200CT. Mosfets are IRFP260
