Kapanadze Cousin - DALLY FREE ENERGY

I tried driving a few different coil arrangements with a ZVS driver running at about 25 kHz,
driving a load through a coil arrangement, and with a tesla coil placed such that the main coil
was in the HV near field of the tesla coil.

Pulsed the tesla coil at frequencies from about 10 kHz up to about 800 kHz with the tesla coil
producing at least a KV or two at its high voltage terminal end, and nothing unusual was noted,
as might be expected. Was just trying to see if driving a coil that is placed in an ordinary HV Tesla coil's
field with the Tesla Coil being pulsed over a wide range of frequencies would have any effect at all on
the power being delivered to a load, but did not see anything at all unusual.

Looks like running the tesla coil at a very specific frequency and tuned for a specific resonance, and syncing
with the low frequency push pull sinewave may well be quite important, and possibly the width (nanoseconds or whatever)
and peak voltage of the tesla coil waveform may be important as well. Nothing new with that, but just wanted to run some
basic experiments to establish if a tesla coil's HV field at various frequencies can cause any notable
effects at all on the output coil's output waveform, or with the power delivered to the load. Looks like various
things may need to be adjusted just right to get the desired effect. Not too surprising.

Akula posted a new video a couple of days ago showing a new gated pulser driver circuit,
using TL494 and '74NC14' (74HC14?) chips. These gated pulses are then used to pulse the primary of his
transmitting tesla coil. Akula also briefly shows a schematic for his dual tesla coil device.
Akula is referencing Tesla patents 649,621 and 685,957 in the video.

I just saw your update Void, i will take a look at it tomorrow.


While waiting on the ordered IGBT's, i went on with the nano-pulse part of the original Ruslan diagram.

Only modifications up till now are:

# non-inverting MOSFET drivers UCC37322 instead of inverting ones  (this could be my problem)
# 74HC14 and 74HCT00 chips instead of 7414/7400
# added R2 / diode input coming from the 2e MOSFET driver into the nano-pulse circuit.
# using 2sc5200 transistor instead of KT805

The transistor is being pulsed driven, but the kacher output is not pulsed, instead i have a slowly pulsating output
The output of the kacher decreases in a few seconds from 900V pp to 160V pp while the 12V input is (kind of) stable at 3A

Guess i have to fiddle around with R8/R9 timing to get the correct pulse, but basically this circuit seems to work.

Hi Itsu. Nice job on that. Yes, the tesla coil will tend to oscillate at its natural
resonant frequency after being pulsed. That pulsing circuit may not be meant to
fire that kacher driver with a really narrow pulse, but as a way to gate the kacher
circuit with perhaps a somewhat wider pulse. As you are probably aware, that 74HC14/74HC00
pulsing circuit originates with Akula, not Ruslan. In Akula's latest video which I referenced above,
Akula is showing a different way to create gated pulses that doesn't use a kacher driver. 

Strange how the high voltage is falling off like that in your circuit after a few seconds.
Not sure off hand why that would be either.

All the best...
