Hi Nick. Have a look at the latest schematic just posted for Ruslan's latest circuit, and you should
see what we were referring to. Ruslan's circuit is quite similar to Akula's second self runner, but Ruslan 
has made some changes. According to the schematics Ruslan apparently posted, he is actually driving the load
output coil windings on the air core transformer directly in series with the 28 turn secondary winding on his yoke core.
The effect of the HV kacher pulses is supposed to boost the output power, so it may well boost the output
voltage across the load to a higher voltage than you might expect, assuming this really works as claimed.
All the best...

  Void:
   Yes, that's the assumption...
   Ruslan is driving his air core output coil which is 24,24, 12,12, 6,6 instead of  the previous (48,48, 24,24,12, 12) that he had shown, from the yoke's 28 turn secondary coil, along with the bulbs is series, as well as an earth ground.
 That's really different than how he showed the previous set up.

  My yoke's 20 turn secondary coil's output is about 80 volts, although my meter can't measure it,  I just look at the 100w bulbs lumin levels, as an indication of probable voltage and current readings. This yoke's output by itself will light my 100w bulbs to about 40%, or so brightness levels.
  So, to go from my yoke's 20 turn secondary coil, connected in series through a tuning cap, to my air coil's output coil, which has 168 turns on it,  should give a healthy output.  Plus, having the kacher/exciter on top, to boot.
  We'll see...

  Each circuit diagram that Ruslan, or Akula are coming up with, is quite different, and also more complex than the previous one.
Makes it hard to try to keep up with these guys.

You are doing well considering you don't have a scope. 
For sure there are a lot of circuit variations out there, although these particular devices 
all seem to be all closely related. I am running some tests as well as I have time.
All the best...

Void, do you know what parts are these inside the red cycles? Especially the first one which is at the mosfet side?
Good lack with your tests..

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.

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?

I don't know what the purpose of that 'NTC5' component would be. 
It was originally on Akula's schematic however.

Usually thermistors go straight on the heatsink. But i also can't figure out how this work on here!
Thanks anyway

It seems it is a thermistor, and it was meant as over temperature detection for
the series tank capacitor to detect over current in the tank circuit?
'NTC' if that is the case would indicate 'negative temperature coefficient',
so the thermistor's resistance would drop with an increase in temperature, loading down the
resonant tank circuit. This may not be a critical component in such a case. 
He is using the symbol for a thermistor, so it may have been put in there for over heating / over current
protection.

hi Jeg,

I think you are right on using resistor 7.5ohms in parallel with diode for around 25volts supply.I do admit it's a uncommon setup.

150 ohms is more suited for around 600volts...1200volts coupled with hv diode.
