Akula 1 KWatt Free Energy Generator

This schematic doesn't make sense, how are they running a PSU on high frequency AC? did they change the diodes in it?

The driver circuit looks a bit complex unless you are looking for a timing/phase shift. the HV section looks to be problematic IMO, why not use a current transformer instead of the zeners? you can then trigger the self resonance without running the risk of burning your transistor. and keep some isolation in the design. some of the driver section could be replaced with a FET driver chip IMO, fewer parts required.

I think the same can be built using a 12v SLC Battery, an Inverter, a SSTC driver and some hand made coils. I have most if not all of those parts, I think I will play a bit.

How Dally run PSU on hight frenquency? PSU have inside 4 diodes. You think, that that diodes can not rectifer 10-40 kiloherc?

@MenofFather,

Most switch mode PSU's use the least cost parts thus they would not usually use diodes that would support high Frequency sources.

As for why, check this out  http://electronics.stackexchange.com/questions/97780/using-normal-diodes-to-rectify-high-frequency-waveforms

this provides a pretty good reason why cheap diodes fail in high freq applications.

I am saying that if the PSU used was not modified, I do not think the input bridge rectifier diodes are of the high freq type. I would like to see a schematic of that PSU and check the diodes to see. I even call on the above schematic as the bridge rectifier , "Br1" if not a schottky type will not function for long as this transformer is putting out 35khz correct?

Anyways, the design is similar to the one using a 50/60hz modulating signal if you look at it. The yoke is used to make a transformer that can support high frequencies, using the split core technique you might gain some efficiencies.

To me the 1Kw unit above looks to be using a tank configuration off the yoke to the cap and coil on the air core transformer. You said it would operate in the 35khz range correct? So this akula device uses 35khz with HV pulsing, has anyone checked the inductance of the coils or swept them? what is the operating freq for the tesla coil side?

so it looks like from the waveform the 35khz signal is 90° roughly out of phase with the HV pulsing.

Just sayin'

Hi

I do agree the diodes typically used are 1n4001 1Amp or similar 3amp version.

Base on my research all full bridge rectifier that i have been searching for are designed to run on mere 50hz or 60hz only.

Not even spotted a 400hz version at all.

Unless its been modified with 400 or 600v fast response diode with around 100ns or less

Dally write, that he divice work and without diodes aditional, but with aditional diodes it work more stable So standar diodes, I think can rectify prety inought well frenquency up to 40 kiloherc, maybe with small eficienty. And maybe Akula remade little PSU (use faster diodes and less indution chokes).
It can operate in 35 kiloherc, yes.
That frenquency of Tesla coil, I don't know, but I gues, that betwen 500-2000 kiloherc. HV not pulsating, HV have standar sine wave. So is two sine waves. One let say 35 kiloherc, other, let, say, 1500 kiloherc. So I not imagniate how here can be synchronisation and how it can made any influence. See my video, were I showing in last video osciliogram with green sine wave? I here put oscilioscope on resoanant capasitor, who in akula schematic is green. And how you see I get same osciliograme like in ruslan video. Only my kacher frenquency seems lower and lower of it voltage.
