Hello Team!

in this thread i will post an idea for an experiment with a solid state device which hopefully will make possible the development of a  self sustaining resonant generator. Anybody who wishes to participate  with bench work or theoretically is welcome to do so. The basic idea is to use opposed like magnetic poles which generate a stressfield and this is fluctuating alternatlly on on e or the other side of the secondary(outputcoil), very similar the Figuera device ,but in a pulsing manner not with linear movement. this is the schematic of the basic idea:

Hey Vidura,

I believe with your ideas, youre on the right track and you have working provable concepts. I think this will be the same.

Thanks for sharing!

A brief description of the principles: For startup a signal with the resonant frequency is fed to the circuit, which begins oscillating from the capacitor thru the primary coils, which are on both sides of the core in two layers,one CW and one CCW wound, the windings have a different number of turns, but are symmetrical on both sides.The two diodes forces the currents to pass thru the coils in the manner that always the same like magnetic fields are opposed, one half cycle on the left side of the secondary and one on the right side, thus producing a unipolar stress field in an alternate pulsing manner.This polarizing the central core section with the feedback and the secondary coils inducing power im them. Of course there are needed many tests to define the convenient parameters for the setup, cores. windings, capacitance, frequency and so on.

Hello 

Today i had a little bit time to begin with this project. As a first step i made a "Toy model" on a ferrite bar to test some basic parameters. The setup looks like this:

there are two coil sections with 90 turns CCW on each side and two layers with 75 turns CW about them , a Signalgenerator is attached on the capacitor (2.2uF) , the diodes are shottky type 1n5822 . it was easy to bring it to resonate at about 3 kHz, the output is very low when the output coil is centred, when moved to the sides it increases. I guess the displacement of the stress field and its intensity is still too low , also I'll test some different  output coils.

Anyway i want to comment an interesting observation that i made. When the output coil is open circuit  the output is in fase or at 180° , depending on which side the central coil is moved. But when a considerable load is connected  the fase angel shifts to 90° or 270° on the other side. It looks as the CMMF is causing this fase shifting. 

As soon as i have time i'll post a video with the scope shots and more tests.

Another test I made was attaching two small neomagnets at the ends of the ferrite rod, with the two N poles facing to the centre, aligned with the fields of the coils. Then the resonant frequency rise to 15kHz, also the amplitude of the primary increased. The flux density shows to have a direct influence on the resonance frequency.

Hello, Here is the video from testing the setup.

The effect shown in this experiment regarding the fields i guess there can be seen the effects of the B field and E field of the device , which are at 90° axis and also  at 90° fase angle. The fase shifting  between primary and secondary seems to be effect of the CMMF

Reguarding the fase shifting in this experiment, as the primary circuit is in resonance it can be presumed that it is reactive power, and should take no energy from the source , only I2R losses , But the output has current and voltage in fase so there is real power.

as shown in the video using the field which is perpendicular to the core axis there is almost no effect on the primary oscillation, but when used a axial aligned outputcoil the oscillations are dampened.

If i said something wrong please correct me.

This is very interesting Vidura.  I have a couple of questions. 

The scope shots are showing voltage I imagine.  If that is the case I would love to know the relative phase angles between the voltage and the current at both locations in the circuit.  The lamp is a resistance so the current and voltage sines are very likely in phase relative to each other.  The other is a little more complex due to the capacitor in the circuit and the voltage and current may well be in phase there also.  If that is true, you have achieved something that is quite remarkable.  

If the voltage and current are both in phase at the input end you have a power factor of 1.  And if, as it appears it might well be, that the load and primary side are  90° displaced relative to each other, as it appears they are, you are certainly onto something.

You deserve success Vidura.  No matter what the results of each experiment you undertake, you maintain extraordinary enthusiasm and attitude toward your goal and it is inspirational.

Hi Vince, Yes as you said the voltage and current on the output are in fase, on the primary side i have not measured the fase angle still, i will try to check with a current transformer probe.

Thank's Vidura.  Your circuit is pretty wild.  Trying to trace what is going on and when it is happening is quite challenging, at least for me.

Your scope shots have me curious.  If your supply current and voltage are in phase it becomes very very interesting indeed.  If not for the cap I would expect to see the voltage and current at 90° phase angle at the supply.  It may still be, but it would be good to know.

(correction) If it were 90° at the supply that would be a power factor of 0.  I would much prefer to see them in phase, and yet also see them both at 90° relative to the load.  Then something unusual is happening, which would be a good thing.

You get more done in a day Vidura then I manage in a week.
