Kapanadze Cousin - DALLY FREE ENERGY

[lost_bro]

I think  Grumage built this device I wonder if he will re-look at his device ?
Also the coils l5 to L9 I 'm not too sure how they are wound but won't they have to matched with a transmission line device ? is that what his spectrum analyzer is for ?

Good day AlienGrey

Think you hit the nail on the head............  I believe it will be difficult at best if not impossible to build this without a Spectrum Analyzer. 

Imagine stacking the nodes/antinodes of multiple standing waveforms in a multi-layer air coil.

Where to start?

Maybe with the ground plane......... and all other capacitive interactions ( design & ambient).

Yes, a spectrum analyzer would be a great assistance.

take care, peace

Imagine stacking the nodes/antinodes of multiple standing waveforms in a multi-layer air coil.

I wrote something similar in the very first page of this thread. See the quote below:

When a standing wave is induced into a shorted coaxial cable, it is possible to align the nodes and antinodes of the standing wave by folding the cable in such a way that theese nodes are next to each other, e.g. by folding the cable into a serpentine or a helix.  This special arrangement will lead to the superposition of the perpendicular E and B vectors of each fold or turn.

For this to happen in a coil (helix) the distance between the nodes of the standing wave has to be equal to the circumference of each helical turn of the coaxial cable.

However, while I know how to make create standing waves and superpose them in a helix, I do not understand how this leads to energy gain.

FYI: Those ISDN Telco transfomers work very well as GDTs and they are quite cheap where I live.

Hi Verpies
Is it possible to attach a link for those transformers? Even i like more making it myself, i am curious to see their frequency ranges and prices.

Hey Lost_bro
With just two posts of yours, i can make a complete guide for GDTs!
For sure my next driver will be a double ended one! For now, i will try today to make a braid wire out of thinner gauges, and add the 1n4148 across the gate resistance. I'll post my new scopeshots.

Zener for now is out of discussion as my 12V supply is not enough for this.

Question: I use a 4.7 Ohm resistance between my mosfet driver and the decoupling capacitor at the primary side. Do you use a resistance at this point?  Or do you connect your driver's output straight to the cap and primary? I used it as i didn't want to overload my tc4420 but probably i have to take it at a lower values like 2 Ohm or so, or to omit it at all. As a gate resistance at the secondary side i use the same 4,7 Ohm for both of my mosfets.

ps. 650Khz is not my actual speed. It is just the value which my scope sees between the cursors, but these cursors were in a random position while scoping.

I'm working at Ruslan 7 replica, I still have problems with spikes and shifting signals on yoke. A strong snubber is minimise the amplitude of signal and change the frequency on inductor.

Hi Conico,
I have also some dangerous spikes on the source/drain side of the IRFP260M wich allows 240V..
What i see on my Ruslan7 setup is maybe someone like Verpies, Jeg or Lost_bro reconizes?

Duting driving only the 3 turn coil connected to the inductor i really have nice clean rectangle waveforms.
As soon when i increase the load by using the 30/45/60 turn secundairy connected to the kacher part the source/drain spike occur at the rising edge of the output wave.
It is a very sharp puls.
Also one of the fets has a significant higer puls then the other.
I use 10nf/100ohm snubber which stays cool normally, un fortenately it isn't capable in absorbing the high puls.

Since i reorientated my drivers close to the gates no treshold spikes occur on the gates anymore.
Also i have no significant HV interference little fuzzy resonance at the high level gatesignals...as this seems to be normal.
So it all improved a lot since last posted pictures. But it seems, altough Conico shows no pictures he has the same problem.

Can someone give some suggestions what to do about it?

I too know very little on this subject but remember doing a telecommunications course years ago, it's something like energy is being transmitted down a coax line as a wave but if you get a mismatch going back the other way it destroys your driver stage from what I can remember, however Eric Dollard is your man and he has a paper on it but it's not free if you look on his web page under his crystal set project you should find some relevant info there.
