Your picture where you have drawn the capacitors...

To achieve 0.414uF that I have, use a 0.33uF in series with a 0.47uF.  That gives you 0.194uF.  Next parallel a 0.22uF with the 0.194uF for a final capacitance of 0.414uF.


Now let us reverse engineer what we think Ruslan may have...

The final capacitance formula is

y = 1 / ( ( 1 / (23.5uF + x ) ) + 1 / 47uF )

Let us assume Ruslan's induction heater core is very close in inductance to mine, 193uH.
If Ruslan is running his coil at 15KHz, then y should be:
0.583uF using this online calculator:
http://www.1728.org/resfreq.htm

Now solve for x:
0.583uF = 1 / ( ( 1 / (23.5uF + x ) ) + 1 / 47uF )

Looks to me like Ruslan has a different connection schema, otherwise the little white capacitor must be very large.
My feeling is Ruslan has the three caps connected similar to my setup with the small white capacitor acting as a trimmer.  I don't think all three red caps are 0.47uF, otherwise the base capacitance would be 70.5uF.  That seems a little high to me.  Of course it is possible his inductance is much lower than mine.  I wouldn't discount that for a moment.  It's still very possible the induction heater coil need not be one half the wire length of the grenade coil.  In which case he may only have two layers instead of three like I have.

hi.
I see or am I wrong or something does not agree because there are 3 pieces of red and one white with a length of 18.7 m is if you really are 3 layers?
rather important information about how much turnover does your inductor in the first layer?

[Tomtech29]

it will be difficult with this calculation see here:
It selects the LC resonance, and here you can see that there are 3 pieces 0.47 one white 0,? and another 4 pieces smaller fine mess?
-logic went into the forest (having a length of wire frequency to calculate the capacitance of the capacitor )?

let everyone do like him better I do not want to suggest anything just pure curiosity for discussion .
(I used only 2 pieces 0,47uF parallel and have resonance 15kHz) and indicates that a lot of misunderstandings.

Hi Tomtech. This guy tested three different TL 494 chips and he found one that
could create pulses at about 1.75 MHz. Unfortunately he does not list the manufacturer's
part number. He only lists the markings from the top of the chips, which probably doesn't help much.

Тест микросхем TL494 на частотах свыше 1 MHz.
В последних видео Руслан Кулабухов продемонстрировал возможность работы микросхемы TL494 на
частотах свыше 1.5 MHz. Целью данного теста является определение максимальной рабочей частоты
TL494 разных производителей в генераторе пачек.

"TL494 test chips at frequencies above 1 MHz.
the latest video Ruslan Kulabuhov demonstrated ability to work TL494 IC at frequencies above 1.5 MHz.
The purpose of this test is to determine the maximum operating frequency different manufacturers TL494 generator packs."

There are other PWM chips available that can be used up to 2 MHz or 4 MHz.
Here are a few examples of PWM chips rated at 2 MHz or above. You would have to research if any are
suitable for this project. 
MC34067PG - 2.2 MHz - 16 pin DIP
HV9123P-G - 3 MHz - 16 pin DIP
UCC29422N - 2 MHz - 16 pin DIP
MC33067PG - 2.2 MHz - 8 pin DIP
UCC35706P - 4 MHz - 8 pin DIP
TL1454ACN - 2 MHz - 16 pin DIP  <-- Dual channel PWM chip
HV9120P-G - 3 MHz - 16 pin DIP

There are other PWM chips which may be suitable as well.

All the best...

We might have to use far more than 12 volts to obtain this in a  test some of the chips can operate up tp 35 volts but will need interfacing who knows, Any one ?

  As I mentioned,  I think that it's better to stick with the previous schematic, as we don't know much about the newest version. Or even IF what we see in his last video is for real, or not.
   There must be good reason that Ruslan is not showing the Kacher circuit being disconnected, while running a full load, I suspect.  Or why would you not show that, as it's not a small detail. And it would certainly help to convince, at least me, that he's on the level.

  The TL 494 boards that I posted the link to is a push-pull topology, if you didn't notice.

   Here's a picture of my new yoke, wired up for 24v input.  12, 12, turns primary, 28 turns secondary.
There is a 6 turns, 6mm winding for the other secondary, (which normally has three turns winding).
With all the windings this yoke measures 3 7/8 inches wide at the base.
