Akula's circuits- is this the principle?

Vidura posted this 03 September 2018

Hello Team, after watching one of Akulas videos several times(Trance and Resonance) I think to understand a little bit better the principals of operation, and so I will share this observations here, hopefully adding up some useful information. Specially this circuit which is quite simple seems to be good to grasp the principle how it works, and also is cheap and quickly for built, in order to try to replicate.

Edit: viewing the valuable information about andrey melnichenkow that Chris has posted it becomes obvious that the credits for this discovering and buildings are corresponding to him ,and not to Akula, who evidently has merely copied Andrey's work.

This is the schematic he is explaining on the video, I'll post the relevant details: the test points are highlighted in the colour of the scope traces.

He seems to point out that the CD4069  inverter is not needed, or not important for the basic operation, at least the shaded area, the inverter connected to the external FET forms a synchronous rectifier I would guess and could be probably replaced by a shottky rectifier if the CD4069 is not employed . The resonant oscillations are driven by the MC34063 chip, which  is an analogue dc-dc converter driver. Here the internal circuit from the datasheet:

Now this reveals a very important aspect of the operation principle: note that the fundamental frequency of resonance is 269Hz (the low value indicates that the coils are bucking), but the switching frequency of the converter is set to a much higher value by the timing capacitor C  on pin 3(for 300pF it is approximately 25uS  Ton and 10uS Toff). The Inverting Comparator input on pin 5 will shut down the switching when a the threshold voltage on the output is reached. So when the output voltage downscaled by the resistor divider  on pin 5 becomes greater than the 1.25V internal reference, the driver shuts down. With this technique it can be achieved by adjusting the variable resistor , that the switching occurs predominantly at the lower halfwave of the cycle(in the case of the boost converter, where the pulses at the yellow highlighted test point are negative), which will maintain the fundamental resonant oscillation with a minimal expense of energy.

Another detail that has called my attention are the copper sheets inside of the bobbin, which are found on some other devices of Akula as well. I don't think that this is a emf shielding, more likely it forms a capacitance or capacitor in conjunction with the second sheet at the inner end of the second winding. This will of course have no effect at the fundamental oscillation of the coils at 270Hz, but referring to the switching period of the driver with a 35uS period it will have a mayor effect, and might be used in this design to achieve a capacitive coupling of the second coil.

Note that in the following screenshot the schematic sheet which is below the circuit in the video has two modifications marked:

First a resistor in series with the output Led's -likely a impedance correction

Second the variable resistor for the shut down signal is changed  to a diferent configuration - for a broader range of adjustment


I think that this particular circuit would be a good start point to experiment as the basic design is quite simple. And in my opinion first the coil set have to be tuned to the fundamental resonance frequency, which is the tricky part, then the adjustment of the driver pulses and load impedance should be easier.

Also  I wanted to point out that in the other device  that Sergei Panov has bought from Akula in one of the videos where Sergei is explaining the principal of operation , he shows a very similar concept to apply a gated pulsing on a fundamental resonant oscillation(10 to 50kHz) and explained that the pulses coming in this case from a teslacoil has to be applied in the second quadrant of the sinewave in order to get the power amplification in the lower frequency resonant circuit:

Hi Vidura,

I replicated this circuit. Its a little difficult to get to the right working conditions if, like me ones electronics skills are only satisfactory.

I found putting a Variable Resistor on Pin 5 of the IC, I believe it was without consulting my notes, was a great help.

The Top Rail must be bought down for this Circuit to work, which initially is very un-intiutive until one finds that this Circuit can not work unless a Current is drawn, creating a Magnetic Field, "Generating" Energy to thus in-turn Charge the caps.

This lowering of the voltage also makes the IC increase in Frequency, via the Sensing Pin.

I spent a lot of time on my replication, but I learnt a lot!

I shouldn't, this will open doors for Trolls to discredit, but a video to share. Some of my very early progress: 


This was way back, years ago, when I first started replicating Akula's work. I spent a lot of time, but eventually, got it working.


Please remember, this is exactly the same as, and a copy from Andrey Melnichenko's work. Akula took Andrey Melnichenko's work, never gave him credit as far as I know, and portrayed it as his own:









P.S: Do you recognise this guy: Arthur Trankle of STEHO Energy?


I hope this helps a little?

Thank's Chris for this Information, it's true that it might attract the attention of some Troll, but the most important is that it can help to get better understanding of the principals ,and encourage to more replications. If the members of the Forum are helping and supporting each others, it will be easy to deal with the Trolls!

Very interesting diagram, I can not read correctly at pin 3 the capacitor,

is that you will have another picture more clear but I see that you wrote further in your post 300 pf is it?

about EMI shieldind a possible explanation, see what they wrote in my electronic book,

Shields also intercept radiated noise and return it to its source through a low impedance.

Thus the need for a low resistance ground back to the source using the shortest possible path.

Hi Jagau,

I checked the video again , the Value of the capacitor  is 510pF, not 300. Altough in my guess the frequency of the pulses is not that critical, but it might be a good idea to use the variable resistor on the supply of the ic as chris recomended and as used in the original schematic from Andrey:

I still dont have tried ,as i have to order the ic and the ferrite pot to do so. 

Regarding the coppersheet i think that it might couple with the asociated E-field without loading the souce, but this is just my guess.

wish you success with a replication if you have planned to do so.

You Guys are just awesome!

I saw none of this cooperation whatsoever on the other forums! I have worked by myself for many years, isolated, taking many years to achieve simple things, you guys doing this together are making huge progress in only days!

I am a proud man to call you all my friends!

As we have learned in The Mr Preva Experiment and other threads here @ Aboveunity.com, the Currents in the Coils are the key factor.

  1. One Current ( I ) moving to the left.
  2. One Current ( I ) moving to the right.

Both Output Coils have individual Output Characteristics! Voltage is a Polarity, it can be Increased or Decreased. This is just a Geometry. Voltage is a Non Work related Quantity, stepping up or down at any time with some simple changes.

Current is a Work related Quantity, and we already know how to Amplify it, it is very easy to do!


CD may like to comment on this? My Thread: Some Coils Buck and some Coils DONT - Possibly may be one our sites greatest resources for those wanting to learn about these Currents in these Coils!

In this last schematic Chris we have 3 vectors identified by H1 H2 and H3
does that mean that we are creating a new H4 vector or we have an H3 current amplifier ??.
It is clear that the 3 coils are in series.

If you make your device repeat the MrPreva experiment effect many times, that's a sure way to amplify the current. But even if you do it once per cycle, you will still see current amplification.

If I may give my answer, I guess that the magnetic field concentrates fully in the third coil, so H1 and H2 cancel each other out.

Hi Jagau,

CD is correct. The Vectors are slightly confusing, normally the symbol ( H )  would be associated with the Magnetic Field Strength as you know. However, in this case we are specifically seeing an Arrow in the direction of the Current. We do, however, see the Curl of the Magnetic Field to indicate the Magnetic component also.

If we review the equation and substitute ( H ) with ( I ), because the symbol for Current is ( I ), and also some quotes:

I1 + I2 + I3 = I3


Keep in mind, a standard Electric Transformer,.



Lets imagine the Current as M.M.F, Magnetomotive Force, because it is, and look for a Hole:

I1 + I2 = 0

The answer is Zero because I1 is Positive and I2 is negative, this is one way to look at Current Vectors of a Transformer: 


Each Current Vector, one in the Positive Direction and one in the Negative Direction Cancel each other out. Thus, my previous use of

1 + -1 = 0


Or, another way to look at this, and a huge push with a big stick for those that are new to this, is Parasitic Inductance:



Lets imagine, we have a very high speed Circuit requirement, very basic layout of two singular sub circuits above. We have our Traces, Copper Busses on the PCB too close to each other, and the operational frequencies are very different of the two sub circuits.

One circuit is 10KHz and one 50MHz.

We will have massive problems with Stray Inductance and get a lot of noise on the Sub Circuits, simple because of the inductances and the Time Rate of Change of the Magnetic Field created bu the Currents in each Sub Circuit.

Importantly, the Signals will also be equal and opposite this the Arrows to indicate the Vectors of the Noise caused by the Parasitic Inductance.

Some take Rabbit holes, call this Capacitive Coupling, and it is, but remember, E and B are the same thing, one is the other, at 90 degrees. Move one and we see the other.

Remember what Floyd Sweet told us:



Conventional electromagnetic theory proposes that when an electric current flows down a wire into a capacitor it spreads out across the plate, producing an electric charge on the plate which in turn leads to an electric field between the capacitor plates. The valuable concept of continuity is then retained by postulating "after Maxwell" a displacement current. This current is a manipulation of the electric field ( E ) between the capacitor plates which has the dimensions of electric current and completes the flow of electricity in the circuit. This approach permits us to retain Kirchhoff's laws and other valuable concepts even though superficially it appears that at the capacitor there is a break in the continuous flow of electric current.

The flaw in this model appears when we notice that the current entered the capacitor at only one point on the capacitor plate.

We then are left with the major difficulty of explaining how the electric charge flowing down the wire suddenly distributes itself uniformly across the entire capacitor plate, at a velocity in excess of the speed of light. This paradoxical situation is created by a flaw in the basic model.

Work in high speed logic conducted by Ivor Catt has shown that the model of lumped capacitance is faulty and displacement current is an artefact of the faulty model.

Since any capacitor behaves similarly to a transmission line it is no more necessary to postulate a displacement current for the capacitor than it is necessary to do so for a transmission line. The excision of "displacement current" from electromagnetic theory has been based on arguments which are independent of the classic dispute over whether the electric current causes the electromagnetic field, or vice versa.


Why is Ivor Catt famous? Because he worked in High Speed Logic, to do what? Solve many of the Parasitic problems associated in IC's. How did he solve these problems? By understanding the Cause and Effect of the Time Rate of Change of the Magnetic Field.

In completion of the source problem, we see an additional Current Vector, thus an Induced Current via Electromagnetic Induction. We see a Gain in Current because:

1 + -1 + 1 = 1




I1 + I2 + I3 = I3


We see a Gain in Magnetomotive Force, a leverage, where a standard Transformer uses all of its Magnetomotive Force and can never be over unity, because we imbalance our forces, we now see gains. We have left over MMF!

Please Note:

One must think Electromagnetically Induced Currents! Not Forced Currents. Please note, these Coils are not Bucking because we make them Buck, this is entirely an Induced effect.

The introduction of a Third Coil, and the Electromagnetically Induced Effects of the Third Coil satisfy's Newton's hidden Law's of Motion:

Action, Reaction and Counter-Reaction


Voltage Polarity and Current Polarity can be in very different Directions!

Regarding the three coils from this  basic schematic from Andrey i would like to share some thoughts about including the context of the boost converter.

when wee look at the first step of swtiching: S1 is open and S3 closed ,all three coils will build up a current= magnetic field, but as two of the coils are opposed there B fields cancels each other, but do not eliminate it, as current= magnetic field is present.This also will cancel the impedance of the opposed two coils(exept  I2R losses)(H1+H2=0), and the overall impedance will be only the corresponding to L3 (H3) . This will allow a very fast charging of the inductors.

now let's look at the second step of switching(remember at this moment current is flowing thru all coils): S2 closes shorting coil L2 backlooping the flowing current to itself, simultaneously S1 opens interrupting the currentflow to ground, and thus giving rise to the BEMF which provides current flowing thru the diode to the load. But as L2 is shorted out in this instant the MMF of L1 and L3 wich are not opposing will add to the value of 2 * H3 doubling the output. so it should be possible to feed back a part of it to the source  and keep the device running.

If i made some mistake in this assumptions your corrections are welcomewink

Hey Vidura,

When I first started looking at this circuit, I was in an undecided state as to the timing of the switches.

I felt as if this was a Pseudo Circuit, to give guidance. Reason being, shorting L2 via S2 at On time or at off time made no real sense other than Inductance change in the total Coils Inductance.

Inductance change, depending on where the Magnetic Field is, does make some sense, but was it enough to see a gain on the output? My initial experiments did not show any good evidence.

It was the study of, and replication of this circuit that gave me the answers!



The 4069 Hex Inverter brings down the Top Rail as determined by the polarity on C2.



When tuned, this is the blue Sinusoidal signal, seen here:



Which is also impressed, and seen, on the Yellow trace. We all know, but others following, Electromagnetic Induction, its going to happen as explained above!

C2 can only discharge through R3 ( 1 Ohm ) then to X2, which has 2x Coils indicated in series, out to X1 up to D1 and then to Ground via U3. Of course U3 is switched by U2, the 4069 Hex Inverter. So if you like this is a feed back Oscillator, a slightly over complicated Voltage Controlled Oscillator.

The Magnetic Field and thus the Current rising and decaying sinusoidaly via 2x Coils, or twice the inductance of the other Coil according to our above diagram.

Current in the other Coil, connected to X0 flows in the opposite direction, this Current Charges the Cap, C2. We seem to see a problem here however... This makes no sense for the IC U1, the MC34063.

All Buck Boost converters are Current based, or Magnetic Field based devices. Their efficiency comes from the Efficient use of Electromagnetic induction. Short Sharp Pulses, which is what the MC34063 is designed for, requires a low inductance coil.

We have our answer here:




The Coils are not drawn correctly on the above Circuit layout. The Coil with the lower inductance needs to be Pin 1, the DC Boost Converter Coil. This is a critical and common theme on all devices. Short Sharp Pulses need a low inductance.

A sharp pulse on a Low inductance Coil will Induce a Higher Voltage on the Higher Inductance Coil.

Current then can increase further because: I = V / R

where in this case R is low anyway.

The Arrow and indication of "Negative Back EMF" charges the Cap C2, this is "Negative Current" which we saw in The Mr Preva Experiment, and also in my Thread, Some Coils Buck and Some Coils DONT.

Positive Current and Negative Current are doing a Push Pull, topping up Caps at each part cycle.

The Equation:

l1 + l2 + l3 = I3


We have I3 "Generating" the Device Run Energy! This is our Gain.


Its worth noting, Akula had a few go's at this:


I hope what I have shared does not confuse anyone? I hope its useful and insightful...

I made some calculations on the timing capacitor of the MC 34063
and I get between 40 and 44 kilohertz for 510 picofarad.
Do you get the same frequency?

This would make sense since the final frequency must be 269 hertz if we take into account

Hey Jagau,

Thanks for sharing your calculations! I would have to consult my notes for the Frequency, but it was low. Of course the RC Time constant will vary from one to another device.

I sometimes leave a Terminal Block for the change of Capacitors in my Circuits, this helps change one out without too much trouble.

Hi Jagau 

Regarding the Mc34063 IC find the datasheet attached below. There is a graph where Ton and Toff  can be approximately seen. As it is an analogue device the timing is given by the charge and discharge time of the capacitor on pin 3 and thus it is also influenced by the supply voltage of the device. You can use a variable resistor on pin 6 (Vcc) for fine tuning, there might be some benefit if tuned to a harmonic of the fundamental resonance. The duty cycle is fixed in this device , it works in "hiccup mode" shutting down the oscillator when the threshold voltage on pin 5 is reached , this can be adjusted with the variable resistor  on the output voltage sensing line.

When properly tuned this will make self oscillating virtually any RCL circuit ,regardless what the fundamental frequency is. I still have not received the materials to try to replicate, i had a lot of work these days and not much time to continue. In my guess the critical thing is to get the coil set and the capacitors of the fundamental resonance circuit tuned. 

My impression was first that the inductance of this coils is  way to hi for a boost converter at this frequencies, but when i made a few tests with a simple setup and opposed coils (1:2 ratio ) i had some unusual effects. Anyway in my opinion the coils are in a different way shown in andrey's and akulas circuits, and this schematics have to been seen with some care, as ti seems that both of them have made contracts with steho energy, there might be important details hidden.

Ok thank you Chris and Vidura for the return.
On the attached image would you have an idea if both coils are
54 uh or 54 mH also for 27uh or 27 mh,
Microhenry and millihenry is a big difference



P.S Thank you Vidura I already have the pdf of IC
