ZVS oscillator driving a DC television flyback transformer like that one above:

http://www.youtube.com/watch?v=4XRwlNCF1PU

The circuit is the standard ZVS circuit that has been posted several times above, using IRFP260 mosfets.

A very similar circuit is indeed used in induction furnaces, but operating at a lower frequency.

Another simple variant of this circuit, at higher frequencies, makes a wireless power transmission system, as I've shown in a bunch of other videos.

The ZVS oscillator itself in this system is driven by 24-32 volts and is only supplying the 5+5 turn primary with a few tens of volts p-p and isn't dangerous itself. But the output of the flyback transformer is 20-30 kV and will kill you quickly, set stuff on fire, etc.

Hi Tinsel

Amazing 'cold fire' on video, how much was output voltage 30KVs? Can you explain me why run up (plasma) spark on jacob ladder?

 Someone asked how they loop the device well quite simply since it is a high frequency device then all one needs is to put it through a bridge rectifier and another special split core transformer. In the backyard device video you can see both transformer and diode bridge in a special pack he designed that happens to be shielded as well. The diode bridge strips the high frequency and then it can be looped to the inverter. :) :) :)
quote from jbigness5  in another kapanadze thread
like the idea to loop the plasma thru a rectifier / transformer / inverter ///////????
will try this this weekend

As I have been working with several different circuits, I've found that the output of two different transformer inverter circuits can be joint together, connected to a bulb like a Cfl along with a series connected incandescent bulb. Then further connected back to the battery positive or negative, which are earth grounded, along with earth grounding the Cfls bulb. This twin circuit along with twin grounds has given me the best light output yet.
 I realize that different circuits will react in different ways, but I thought to add my approach, as it is very simple to build, and has worked well for me.

Today I hooked another flyback transformer with a one transistor driver but did not drive the kapandze generator coil.
I don't know if it's the driver or the transformer cause this flyback is a bit smaller but definitely the kapagen needs a strong driver and flyback to drive it in my experience.
Thanks

Probably if you raise output, in same ratio you must supply input side (if you have on your apparatus example COP=5, and if you want 5KWs output, you need supply 1KW input side). It is my opinion.

Yes ZCsaba probably as you're saying if this one transistor driver you increase input it will be good. I will try this to drive it with 24v and see.
Thanks.

To tell you the truth I'm not sure but I think it's not in OU still or maybe I'm getting very little higher output.
Still have to experiment with earthing;SG;core and caps to see if I can get higher output.

Hi for All

Did someone test/experiments ferrofluid cored on kapa. gen. (except S. Meyer)?

Hello All.

I'm sure most of you will have visited this site, however I revisited and was reinspired. Have a look, it is well worth it!!

http://www.free-energy-info.com/Utkin.htm

Cheers Grum.

PS, I found out I had reinvented the Asymmetric transformer!!! See page 1081, main thread. Almost no one made any comments!!!

 It's a very decent resource for looking at the systems we want to design. But some aspects are modified from the original documents. Case in point the special transformer made by Tesla for his 1892 lecture. In the lecture it states to use wood as the core and in that link it says to use a ferromagnetic core. Don't know which one is right at this point... I tend to lean towards Tesla lecture to be right. But who knows.

Hello jbignes5,

I too noticed that mistake. I feel, like you, that a coreless design will be better for higher frequency. It is still too cold here for me to venture out into the workshop but I have not been ilde. I bought a little PWM module specificlly made to drive Ignition coils (any one can PM me for the details) It is quite capable of 50Khz. However at that frequency you can only run it for short periods of time. But what I noticed is that all sorts of things laid around the operational area were alive. Sparks off bit's of wire, my solder coil burnt my forearm. etc etc. I am going to look at the copper glass aluminium Idea of Don Smith. There maybe, pardon the pun, some potential :)
Cheers Grum.

@ Grumage, be careful with the Utkin doc there are some errors in there, one in particular is the pic of the Tesla bifilar flat coil with the E field eminating straight outward,  the magnitic field is right but the induced E field from it should be circular and in the opposite direction of current flow.  Tesla was a smart cat, why do you think in his diagrams you see one turn inductors with flat coils inside, because flux density is higher inside so the induced E is higher inside and it pushes on those free electrons in a circular direction just like his secondary is wound.  Funny thing though, even with the errors the secret is in that paper too.

Hi Tinsel

Yes, 30 kV or perhaps a bit more when I up the input to the driver. You'll note that I have the flyback transformer totally immersed in oil for insulation and cooling.

That is not "cold fire"... far from it. There is so much power in that plasma that it actually burns the nitrogen in the air to nitrogen dioxide. Even a small JL will burn enough nitrogen to make a significant amount of NO2. This is one big advantage from using the ZVS driver: it is very efficient at transferring power into the load.

The plasma runs up the ladder because it is hot; convection currents in the surrounding air carry it upwards until the gap is so great that the plasma breaks up and stops the current.... then the voltage causes the arc to re-strike at the narrowest gap of the electrode set.
