what you want to use the power amplifier mosfets IRF3205  55V!?
(diode look for me in the old power supply atx something under the sink)

Ruslan was sugesting this mosfet in early days.  I will feed it with 24V max so it is fine. I guess the amps is what is important?     

I have couple more suitable HV mosfets if need. Will see. So far this transistors worked fine with my old push-pull based on signal generator and signal divider. The only shunt on my mosfets was a neon bulb between D & S and all was fine.

whether we are talking about the interrupter to Sewek Tesla ?


push pull   should use 10 Ohm resistor to the gate,  should arm in capacitors with a resistor acting as a filter ,you mentioned varistor securing a puncture and it fooled me it has to be!

in short pulses to Tesla does not apply a resistor in series with the gate of transistor avoid losses for reloading
I do not know at what stage you are and what you construct whose scheme you doing?

We wrote to each other at the same time haa
such a system is tested it myself I have so much that I used irf260
They have a much higher power your transistors will need to dissipate heat so use a good heatsink
definitely like to perform combinations of filter resistor with a capacitor ceramic perish spilki and varystor at this moment will not be necessary!
- could use more good choke on this line positive high-goodness Q (induction coil with a ferrite core with thicker Winding)

  Well, Itsu, that driver looks great. I hope that it does what is expected of it.
  Are you still in the game with the grenade/yoke tests, then?
  As we hadn't heard back from you in a while.

   Why would I want a variable duty cycle?  Why not. Both on the Kacher circuit as well as the induction circuit.  Is that so complicated? Geo has it...  And, I'd love to have the TL 494 mosfet Kacher circuit that is shown in the last video that I linked to.
   It's because it looks like there may be a correlation between how the duty cycle controller can alter the normal wave form, to sort of compress it into having a higher peak. At least that's what I've seen in Ruslan's videos, or have been explained to by you, Itsu, in your own way, concerning  Ruslan's newest videos, and circuits. If I understand it correctly.
  Ruslan's newest circuits have full control. And even of the HV circuit to HV output coil/antenna has a controlled duty cycle, which compresses the wave into somehow obtaining a much higher peak on the scope, as he shows.
So, it looks like the duty cycle controller is also an important point of interest.

  PS. As you may know, I don't understand Russian videos, however, I'm trying to explain it the way I see it.
Could be wrong. If so please add to, correct, etz...

Hi JohnK1
Arduino seems a nice toy to experiment with. Thanks for reminding it. Personally, i am trying first to see the so called effect at the output and then to think about better solutions. In my case, i tune my devices as conico said. Tuning with load connected at the output and not changing it so to retain the frequency steady. I have a heater with 3 resistances of 500W each to play with.

Katcher with variable duty cycle is not a katcher anymore. It is the Allega's blue box where the secondary is connected to ground and not to the base of the transistor. In this situation, duty cycle varying capability is a good future for matching the width of primary's triggering pulse, to the width of secondary's resonant frequency cycle. This matching gives the higher output voltage. But don't forget Ruslan's first devices with his weak katcher's output.

At my last week's setup, i broke my grenade down to two parts. I connected ground between the second and third layer forming this way two coils in one. First two layers is my output coil, and the last 4 layers with a cap in parallel form a self oscillating coil like in Dally design. The problem that occurred is that my resonant frequency is now at 6Mhz sharp (shorter wavelength), way too high for my katcher to work. So i guess there is not any secret inter-connection to Ruslan's grenade as i had assumed of. Back to one and undivided grenade again!
