Ok i located the first component which is a varistor for protection.

The second part perhaps is a thermistor. Does anyone understand why thermistor, and why there?

hi jeg,

It is there to prevent anyone whom blindly replicate."I think it's a preventive measure"
The snubber circuit with 7.5 ohms is strange.

It's typically around 150ohms between diode.No change for the capacitor at 2n2f .

I have provided the Akula snubber circuit previously as a hint.

Latest and final (?) schematic of Ruslan device from here: http://realstrannik.ru/forum/39-kapanadze/134930-ustanovka-ruslana-kulabuxova.html?start=1152#237242

No.

If you build this then you will see that its not strange at all. (I mean the snubber) In fact is the most important part of this generator. The 2,2nF combined with the diode capacity, make a tank circuit with the half yoke primary inductance, and load 24V dc with the high frequency oscillation (when mosfet closes). In my case with 12 turns half yoke primary is about 600Khz... As i have told again, it behaves exactly as a Tesla spark gap but in solid state!
This resistance serves as to help the cap to discharge when mosfet opens. Its value determines the currents which pass through the mosfet...
7.5 ohm is for 25V dc pwr sup. If you raise voltage you have to raise also this resistance. At 300V is about 90 Ohm

  What we need are some close up pictures of the Ruslan circuit to compare with his most resent schematic, so that a proper replication can be made.
  Wesley mentioned that Ruslan in one of his videos had to turn off one of his devices because the transistor was going to blow from overheating. These are the issues that possibly have been improved in both Akula and Ruslan's latest prototypes.

  Akula's first device did not have a separate kacher giving the HV pulses. But, used the choke inside the air coil for the same purpose. And, the input source was 12v DC, instead of running on 24v.
   In the first video, Akula's 12v inverters output was rectified to about 300+ volts, then was also sent to the yoke's secondary coil (24+ turns). Which may have been connected at the other end of that coil to the big air coil. Hard to tell from the video, though. But, it's a very different set up than what he is doing now.
  So, the mosfet or IGBT may require a very different protection circuit, than is shown the picture above of his first device.

No.

Hi MenofFather. Do you mean that Ruslan did not post that schematic?
