  So, as my previous work bench has seen better days, I moved my station on to a new table, and clean up my act, a little.
  I'll have to rewire everything together, now that I have my test gear all cleaned up and working right. Any ways,  it's looking better.

Hi Nick, looks good. Just i would move the measuring devices a bit away from the HV coil ;)

Itsu and D1 thanks for the suggestions. ;) Nice waveforms Itsu. I hope to be the lucky ones!

Skywalker, when one of the primaries conducts, the other primary is open circuit as its associated mosfet is off. So there is no circulation of current to the second primary making it act as a secondary to the first primary. The double voltage seems to me that happens due to the dc charging inductor effect. Richie Burnett explains it well here... http://www.richieburnett.co.uk/dcreschg.html

Itsu,

Thanks. I will need to re-look at my coil and setup. If possible could you please let me know what your output voltage is with a 1K resistor across the cap, without the Kacher working?

Regards

I don't supose any one has thought that we are trying to us a full wave frequency amplifier with rectified output as a switch mode driving power supply here, why don't you just simply use a switch mode driver chip with all it's feed back circuits to do this part of the circuit, I'm sure you can find the correct device for this job and a decent and more efficient circuit on the net. like a TL494 perhaps or buy a module from Maplin or some place else and alter the feed back to suit your requirements.

Have a look at this circuit the 3 and the 5 versions will work well at under 12 volts, Vout is turns windind ratio and feed back. http://www.ti.com/lit/an/slua143/slua143.pdf

No problem now. I have the PC SM Trafo working fine on an SG3525 PWM. I was messing around with a toroidal coil before I found a suitable PC trafo.

Before putting the PLL on a PCB i wanted to test it with the yoke / MOSFETs.

I connected it to the yoke, driving the inductor coil after putting the inductor / 3-turn coil / Wima caps combo to 15Khz resonance.   
It turned out that i needed 2x 0.47uF and 2x 0.15uF parallel = 1.24uF to reach a (series)resonance of 15.4KHz.

The grenade is only loaded with a 40W/240V bulb and not connected to the 28 turn yoke secondary.

Input to the MOSFET's is 24V @5.7A via a PS, the PLL runs on a 12V battery.

Feedback from the toroid (T106-2, 30 turns awg 18) into the PLL.

We have high voltage (648V pp) and high current (75A pp) running in the inductor coil and it seems they are 90° out of phase (current leading)
like being shown in the diagram of post #10839  here:
http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg463092/#msg463092
See screenshot 1 where yellow is voltage across the inductor coil, and green the current through this coil (25A/div.)

Some temperature measurments show this coil getting hot fast.

Also my (old) snubber scheme is melting the link between the schottky and TVS i have across each drain.
Need to change to the new snubber setup.

Second screenshot is the signal on the drains of the MOSFET's.

  I think that there may be more to it, than just providing for the 130v, with no real current behind it, just fluffy voltage. Or not? We'll see.... but, it looks to me like the Kacher coils may also need a couple of amps, to be effective, as well as the right frequency.

Off course, when measuring across a coil in a LC series combination will always show the voltage and current 90° out of phase, even when in resonance.
I should have measured across the complete LC series combination to obtain a 0° (in phase) relation of voltage and current when in resonance.

Doing this (so basically measuring across the 3-turn coil) shows the combined square wave signals from the MOSFETs, but as can be seen in the screenshot below here
the voltage (yellow) and current (green) are in phase (at resonance).

   John.K:  Thanks,  and yes, you're right, but I have very limited real estate on the kitchen table, and am only allowed 1/2 meter square of space, by my wife.  I'll move the Kacher as far as possible, but it has been working ok at even that distance.
In any case, I know what you mean.

Hi
good Job...
Itsu/
could use a measurement of the high amplitude resonance, and what will change when you increase the load Change the bulb with a 200 Watt.
and compare?

As in Thebes will be supported this arrangement Feedback from the toroid

or actually maintains a high current under load changes and, if the output frequency changes grenade on the bulb
such benchmark as did Ruslan 100W+80W the frequency drops 21Khz/27Khzhim but claimed that the resonance is

and one more thing as you now have 5.7 Ampere at 40 W. how many drops  Amp on PSU as you connect the 200Watt ?
 on what shows without switching circuit winding 28
Thanks.

- I asked earlier how does it affect shift (I had the impression that the delay)It will have an impact on current performance but consequently one from the transistor works harder
if this is as I understand .

Tomtech29,


ok, i added some extra bulbs, in steps of 100W, so first the 40W,  then 140W, then 240W etc.

The resonance frequency goes up in steps of about 1KHz but the input current drops significally after adding the first 100W bulb.

Hope this is what you wanted to know.

I added the new kacher driver to the mix to get a picture of the timing of it all.

Below screenshot shows the kacher being fired (purple trace), the inductor voltage (yellow) and inductor current (green)
As before, the grenade was only loaded with a 40W bulb
 
This picture is similar as the earlier mentioned diagram in post #10839  here: 
http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg463092/#msg463092

So we see the kacher is fired at max voltage across the inductor, and i have the feeling it needs to switch on at the peak of the current (green trace).
Not sure how to do that.

Tomtech29,

not sure what you mean here, those signals are no transistor signals, they are the signals on pins 3 and 4 of the PLL chip (4046).
I have set them with the R8 pot to be switching at the same time (compensate for the delay of the feedback signal as i understand it).

See this post:

:D
:D
so all I agree so much that I tried the light bulb to a maximum power of 200 watts still think about the fact that ie the yellow and blue signal is not of the transistor's gate
and both signals in your push-pull are identical 50/50% without which the  delay timer for gates
Synchronization keeps both signals at the gates equally
-it may seem strange to you but I thought that one channel experience bath set at a different time to the second.
