Kapanadze Cousin - DALLY FREE ENERGY

Tomtech, If I good remember, you are Polish right? You should understand Russian

He shows the hand sketch and he says it is necessary to get currents in face between those two LC contours.  Also check where is the ground in his sketch. The output must not influence the LC resonance, he also use some filter which is not on the sketch and than diode bridge.  As he say- The principle of this device is only simple LC resonance and collection of reactive power.

Now my thought:   At the beginning Ruslan was saying- don't search for LC resonance, now he turned 180deg.
Also I believe correct impedance  plays here important role. Can you check what is the impedance on the output coil? (can this help? : https://www.youtube.com/watch?v=ieAhBejHe2M)    Still working on analyzing device.  Couldn't get my cheepo  2CH signal generator conect with labView. It is sorted by now ( I hope) . This weekend I will fire it. I am looking forward t see some test results.

I got my 5KV probe today and it shows some chart voltage/frequency        I am confused from it as the graph shows  5KV up to around 100KHz and in MHz range the graph goes as low as around 500V??  What that mean?  Thanks,

Yes Yes AND YES to all !!!!!!!!!!!!!!   well what did you really expect ?    still if you fill a wast bin with rubbish some time you have to empty it !

Any one got a pointer to the forum ?

  I found no benefit in the two diodes (12R06) placed in series or parallel.

Hi Nick
I think diodes in parallel like that, serve only for adding their capacity, so it is a way for helping in tuning.

Hi Itsu. I followed your advice and I solved my half problem. I returned back to same direction primaries, and now each drain fires according to each gate. Mosfets now are not open all the time and heat reduced to a high degree. I still have less voltage than you at inductor's line. I tried several things like changing mosfets, or bypassing filters, but output remains the same. What I noticed is that when my pwm is at full range 45%, my input consumption is only 3A maximum. Hmm any other idea what it might be behind this reduced output power?

Hi guyz

Jeg, and others

these are some of Urfa's schemax.
look how the connections are hooked up.
try it, these Schematics I used and got some crazy results in effect.

Btw the Diodes act like capacitors! in a way I guess...
Below you also see a pic of the toroid he was using, yellow/green wire one was choke connection for pushpull and
magnet wire ~50-60turns enamel wire is Kacher connections, use the schematics to see how and what.

I do really think it's how you connect it in certain way is how you get the effect.

The Pushpull circuit is one which I also build, the Akula one some time ago, TL494 and IR2110 mosfet driver.
and regular Ruslan kacher setup in use.

Hi Jeg,

yes, looking much better, you now have the basic 48V square wave output, but with some ringing like i had when without proper snubbering.

The low output on the inductor coil/cap could be you are not at the proper resonance frequency.
I see your scope displays 16Khz, so you must have something like 1.2uF of series capacitance, is that so?

If you are at proper resonance for your LC values, then it could be the components or connecting wires.
There is tremendous reactive power running in that series LC circuit, i measured 75A pp 
So if your caps or inductors or inbetween wiring are not up to that, i can imagine that it will not peak as high, but you should notice some parts becoming hot.

Is your 3 turn secondary in the same direction as the primaries?   Mine is.
