Thanks Itsu. I'll connect the grenade back up to the Mazilli/yoke, and see what the frequency reads on the 3 turns coil, and try to adjust it accordingly by using the turning caps.  I still have 4 turns on the 3 turns coil, so that can also be dropped to 3 turns, if needed to further adjust the frequency. 
  I may need to go down to 1.25Mhz for the Kacher's output, as that was where I was also getting the 3mm streamer, and the intense HV stinging was felt. Or the 1.85Mhz, we came up with.
  I have a feeling that all the sweet spots need to be tunes for and found for each device, and not rely on other peoples results.
 
  How's your new push-pull driver coming?
  My head is fine now, as well.  My last post was at midnight, and the spinning was from lack of sleep.

Good to hear it was only temporary   
I still am fumbling around with the PLL and the Kacher drive.

I put the blue box, red box and beige box of the latest ALLEGGA diagram:

http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg461537/#msg461537

on 1 PCB, but i have a hard time locating the ERL-35C transformer (red box).

Up till now i have opened up 4 PC PSU's and severall other swiched mode PS's, but non contains the ERL-35C
Guess i have to put together one myselve, and/or use the verpies lossless setup.

I can test soon with only 24V on the kacher input, to see if the kacher will run with these small pulses
and how the waveform looks like.  Will complete the 24-130V dc2dc converter lateron

Most of these PC SM multi-tapped step-down transformers do a similar job, although their type codes vary. You should be able to find a suitable step-up winding configuration using your LCR, FG and scope. I noticed on the Ruslan video recently posted by T1000, that he appears to be using a SM transformer physically smaller than the ERL-35C, which makes sense, as the ERL-35C is overkill for the required output in this application.

Yes well, whats all this then, it's NBG putting a load of AA When We don't have a clue what  your on about.

Thanks Hoppy,


i guess i have to find a substitute or have to roll my own anyway as the layout of an ERL-35 (which is very hard to find)
does not match with what i need according to the red box diagram, see the picture below, taken from this PDF:

https://www.fairchildsemi.com/reference-designs/RD-268.pdf

Its a 37 turn to 6 turns (or 3+4=7) step-down while i need a step-up.

(or are there different ERL-35 layouts??)


Regards Itsu

I am wondering if this is the missing part of the Kapanadze puzzle.


Any constructive comments??

I believe the FE diagram is here http://www.gestaltreality.com/energy-synthesis/eric-dollard/additional-posts-by-e-p-dollard-2012/

Hoppy,

Ok, good to know,

i will check my transformers for a useable step-up with a ratio of 1:5

Regards Itsu

Itsu,

Thinking about this further, as this is reasonably low powered forward converter, you should be able to drive the primary unipolar, so not needing a centre tap winding. So any main PC SM step-down transformer working reversed should work to give the required 300V DC output @ around 0.2A, when rectified and smoothed. I'll have to try this out myself.

It would appear that the turns ratio of 1:5 needs to be increased, so its quite possible that the transformer in the ALLEGGA circuit was custom wound.

I asked Oleg on skype about this bit few days ago and he just said the transformer came from impulse power supply. He connected it in reverse for step up voltage. For details about model/etc I do not know which is used, probably it may be from one of burnt down PS as there is one for loop-back.

Hoppy,  that would give fireworks i guess 


Regards Itsu

  Most likely! Even the correct 130-135V may be interesting.

Hoppy

Have you guys built this inverter circuit and tested it?

I tried it with several input voltages using a cwsbytemark.com MegaFlux toroid core and was able to adjust secondary turns to pretty much get any voltage I want.  My thought was to run at about 1/3 of the max voltage the IRFP460.  Make R32 adjustable and find C27 to be near a midrange point where the frequency is most efficient for the core you are using.  Try not to run it too fast as the IR2153 can only handle so much drive current on the MOSFETs.  You won't burn up the chip with R30 & R31 in-place, but the waveform will begin to slew pretty bad; consequently the MOSFETs will begin to run hot.  Check the heat on R27.  When things are right, it should run nice-n-cool.
