##### Re: Resonance found close to predicted frequency

resonance found close to 108khz the voltage when to more than 1000v, however the production didn't changed much... woking on that.. .
Hey sebosfato, I have more things for you to think about...

My quess why your gas production is low is because:
1. You do not "Restrict Amps";
2. "Resonant Action" is not started.
You know what Stan means with tunable inductor? Right?

Current will never be restricted when inductors are the same and "Resonant Action" can't be started because charge q and q' are not equal.

When you make a simulation and check the frequency response of the chokes you get lower voltage amplitudes!

Only equal and opposite voltages at the plates can result in resonant action and current is restricted that's why stan indicates "tunable choke" to "tune" to "Resonant Action"!

Think about it, what happens with properties of the choke when it's tunable?

Hi webmug,

I believe he meant tuned not only because is tunable, but because it is in resonance. However yes it must yet be tuned and i think that i understood how.

Basically to restrict the ams the induced voltage (red) by the resonance current must = the resonant voltage (across tx5) or be even be a little bigger than it, so in my understanding this mean that the secondary must have exact the same turns of tx5 and tx4 but the last tx4 must completely cancel the tx5 inductance, for this to be achieved, of course coupling is not perfect so i'm still thinking how to match it.

I think that trifilar is the way, however i think that a triple coating wire must be used. to be able to ensure it can held maybe 10kv insulation.

would be a good idea to have a variable secondary, and tx5 coil, and also primary...=)

Why not checking out the VIC BOX picture. All coils are separate mounted on that core.
Mostly the insulation coating for wire is 2500V when you don't go higher than that, the wire is good enough.
Don't know it how high it can get with step charge. Make sure you have the primary input voltage amplitude low for testing.

yeah I know, but that way the coupling can be really bad, with makes difficult to match the things. and also makes the transistor to hard work cause of increased dispersion (leakage inductance) (energy that is not couple or transferred)

Maybe the step charging wont get so high I thought this too, I mentioned the tricoating to ensure the vic wont burn so the work is not wasted.

we are getting there!

When the coupling is to small or open circuit core, you have to use maxwell equations to be able to determine the transformer interactions.

The closed loop cores can help avoiding this mathematical problem.

The imaginary pulse, is the doubled pulse, but it is also felt in the primary too if you put the oscilloscope across the primary under resonance you will see a square wave having during the off time another pulse of the same polarity.

Sebo,

Here's something to try that I'm playing with to reduce amps.  It seems to work well.  I've reached over 2K volts with my 8xa inductors yet have about a 1/2 amp I can't get rid of with 110 volts off the variac.  By connecting a 150 watt light bulb between the negative plate and the neg lead in i've been able to reduce the amps on the gauge to nearly zero.  It does not reduce gas production.  The light bulb pulses on and off with the gating and is an fine visual indicator.  Now I'm trying to find that elusive and supposed special pulse train length and timeoff length to match my plate gap which is 1 MM.     give it a try for shits and grins.............
