Kapanadze Cousin - DALLY FREE ENERGY

Hi !
Ruslan used a thyristor in that setup  (his words). See 06:55 in this video:

He say, that better use tyristor, then be more eficiently.

Hi Nick. I doubt there is anything special about the kacher circuit itself.
You should be fine with the kacher circuit you already have working. I think the quality of
your earth ground and how the output from the grenade coil is being used
is probably what is more important in that circuit setup.

That circuit setup from Ruslan which does not use the PWM driver is probably not so far off from
what Nelson is doing as far as the basic operating principle. I am basing this on this recent statement from Nelson:
"I just try to help understand that results that people search  are not able to be achieved by induction..."
(http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg478997/#msg478997)

In Ruslan's circuit setup without the PWM driver, the output capacitor is being charged via the strong
electric field from the high voltage end of the tesla coil. The switching of the output capacitor with short
nanosecond range duration pulses will be the most tricky part I think. Then there is the matter of the output
transformer which Ruslan may have explained some details about in the video, but without a line by line
translation of what Ruslan said in the video about the device (Ruslan seemed to provide a fair amount of details),
you will likely be guessing about the output transformer details. We also don't know which frequency Ruslan
was pulsing the output capacitor at, unless Ruslan mentioned that in Russian in the video. Unfortunately that
is a fairly long video, 23.5 minutes, so getting a line by line translation into English might well not happen
any time soon. A translation of any important details about how Ruslan said he is switching the output
capacitor, and any details about the output transformer would be nice though.    

He swithing output capasitor with 15 kiloherc, how he say in video.
About output transformer. First wound two secondaries 1 mm^2 20 turns (conected встречно, maybe he want say in not indutcive way, maybe in tesla bifiliar way), then in other side in rings method primary (that he means in rings method, maybe like usualy transformer wounded). Primary have 300 turns of 0.75 mm wire. He say 0.7 in video.

For 1000 volts you can use IGBT transistor. Maybe better than mosfet and than thyristor.

In this circuit the first stage is just an on time for the first FET through the coil _---_--- like this it inverts the signal so it's output is off, unless it's input is triggered correctly it's off when it should be on ??

With this circuit my aim is to supply 24v dc through the coil of the mosfet and the diode. Resistance divider will be such as to maintain a low voltage katcher oscillation up to the moment that 200v peak is injected.

Menof.
It has been a long time since your last post. Nice to see you again here. Thanks for your contribution.
I have seen again this kind of driving and i will test it for sure. It is just that in a so brief moment, i am not sure if Katcher has enough time to build the needed HV. So i started with the above circuit thinking that is a good way to maintain a low voltage oscillation before firing it. This way katcher doesn't have to build oscillations from zero. But i 'll test it anyway. Thanks

This IGBT will be much slower with quite high 3700pf input capacitance and slow turn-off delay time of 190ns - https://www.fairchildsemi.com/datasheets/FG/FGA25N120ANTD.pdf
You will see it starting drawing current by itself between gate and emitter (drain) like IRFP460 when being run on 2-3MHz range which is required for smooth Tesla coil switching.
This was main reason why I swapped to higher frequency range operating MOSFET STF12N60M2 - http://www.st.com/web/en/resource/technical/document/datasheet/DM00187616.pdf and if you can find better one than this, it can be tested.

EDIT: The IGBT STGW40H120DF2 - http://www.st.com/web/catalog/sense_power/FM100/CL826/SC953/PF255269 might do a job and if someone can test with Tesla coil on 2-3MHz range, that would be great.
