Kapanadze Cousin - DALLY FREE ENERGY

[itsu]

Thank you all for your suggestions, but i would like to first try to get some results with using this basic "Dally" concept which to my knowledge does not use any (elaborate) syncing circuitry between the oscillators.

I know my setup is very different from the original setup, but the basic ingredients are there, so in principle it should/could work

Concerning the effect of the nano-pulse, it only adds spikes onto the L4 signal, it does not increase the basic sine wave level (50V pp), so with or without the nano-pulse, the sine wave (and the rectified dc) stays at the same level (22V dc which lights a 12V/21W bulb at 50%).

I do sometimes notice a spontaneous sync between the both oscillators as that the L4 signal stays steady for minutes with both the sine wave and the superimposed spike fixed in relation to each other.

It's interesting to watch the evolution of the circuitry happening in this thread. The 494-based system with the current phase transformer that Sergey V. posted is getting close to the driver circuitry for my TinselKoil v. 2.0 sstc. I use a full H-bridge of bipolar transistors instead of the half-bridge shown in his diagram, to drive two separate phase transformers, each a trifilar wound toroid. The two anti-phase outputs of each toroid are then used to drive the gates of a second full H-bridge of power mosfets which are switching the primary current to the resonator's 5-turn primary, through a heavy DC blocking capacitor. Using this system I get a pretty good sharp rising edge to the excitation pulse which then produces a nice high voltage swing in the primary winding which then allows the resonator's secondary to ring, and since my drive is at the same frequency as the ring I get massive voltage amplification through standing wave resonance in the secondary resonator. From 170 v p-p at the input to the mosfet H-bridge, to well over 200 kV at the output of the secondary resonator.
This is just an aside comment, really nothing to do with the efforts to make nanopulses, I just was struck by the similarity of design and function to what I'm using for the sstc. Carry on, I need a good nanopulser too, my DP101 can't do faster than about 100 ns risetime any more ....

Thanks TK, i can see the similarities allthough the goals are different, interesting.

All,

i did some further testing, and found the following:

# L1 and L2 do not show the nano-pulse (as the voltages on these 2 coils are much higher (350/250V sine wave) it could be that i do not "see" them).

# putting the nano-pulse on the L3 coax coil shield does not change the L4 signal (same 50V sine wave with nano-pulses superimposed on it).
However, it is impossible to measure the pulse with my HV-probe as my scope if heavily influenced by the spiking and scrolls through its menus spontaneously.

# capacitively syncing the VCO on the L1 coil like mentioned by Black_Bird does not work as the VCO signal stays in control.
However, when both the tl494 and the VCO are tuned to almost the same frequency (4.2Khz), there seems to be a spontaneously lock which could last for minutes, but no special effects resulting from this lock.

# the L4 signal with or without the nano-pulse active is about the same value (50V sine wave).
The nano-pulse only adds spikes to this sine wave signal, but does not increase this nor does the rectified dc on the output cap show any increase (could be my UF4007 diodes are to slow for these pulses?).

# increasing the nano-pulse repetition frequency (needed to increase the number of pulses superimposed on the L4 signal like proposed by T-1000 and Сергей В) severely decreases the nano-pulse output and shows no special effect else then more (smaller) pulses superimposed on the L4 base sine wave.

# Trying to wrap my head around the advices from T-1000 (your nanopulser is making spikes in both ways at once over sine wave and that is killing process) and Сергей В (correct excitation!! Important: stop on peak!!), but this is easier said then done, and does not fit the original Dally design.

Trying to wrap my head around the advices from T-1000 (your nanopulser is making spikes in both ways at once over sine wave and that is killing process) and Сергей В (correct excitation!! Important: stop on peak!!), but this is easier said then done, and does not fit the original Dally design.

I cannot promise that following these advices will lead to success because I do not understand the principles standing behind them but with additional circuitry, I can help you disable the nanopulses between 90deg. and 180deg. as well as between 270deg. and 0deg. of the sinewave cycle. 
Just let me know, when you decide to go that way...

BTW: Are waveforms in L1 and L2 and L4 synchronized in phase already ?

@itsu, @ verpies
My thoughts on Dally's working principle:
First, I want to make clear that this is still a conjecture.
I think the process has to be a non-linear one - if it were not so, you would have energy pouring out of any circuit with a tuned circuit. So, circuits with linear inductors, capacitors, resistors, voltage and current supplies, by themselves, cannot present an OU behavior. There has to be, at least, one non-linear element where the energy exchange takes place.
in Dally's device, the only place where this can happen is in the inverter transformer, with a ferrite/iron core. Contrary to what I thought at first, the important interaction is not between the nanopulser output and L2/L4, but with L1, which will convey the nano pulse to the inverter winding that feeds L1. The nano pulse provides a trigger to the event.
The question is: how does this happen inside the transformer core, what does the nanopulser exactly trigger?
In the operation of the inverter, the B field "walks" over the histeresis curve of the core, normally away from the saturation extremes. When the nano pulse is applied, it shoots the core deeply in saturation, creating a kind of modulation of the core permeability. This core permeability change implies in a change in the secondary and primary inductance values. With the correct relationship between the inverter frequency and nanopulser frequency, and correct phase alignment, this could lead to parametric amplification, that would explain the increased energy at the output.
The roles of L2 and L4 would only be wave shaping (sine wave at L2) and impedance matching to the load (L4).
