yea, I'm going to have to build an insulated cell like yours soon.

Made another VIC Coil, calling this one 'V4'.

Primary: 150 turns of 24 gage (Leftmost section)
Seconary: 500 turns of 30 gage (second section)
Choke 1: 500 turns of 30 gage (third section)
Choke 2: 500 turns of 30 gage (Rightmost section)

Sections:
ID 0.775"
OD 1.495"
L: 0.258"

with 150:1500 step up, thats 10x, so 10 volts in should get me 100 volts out, yet i am getting 400...500...900... maxed out meter.

gas production is due to miliamp leakage

control and driver circuit patent says "will draw 25 milliamps, but will drop to 1-2 miliamps in a tuned resonant condition"

I need to find resonance, any ideas?
I should get an LC meter...

Once again, very nice work! If I may, I would suggest a couple of things. For future windings of the transformer and chokes, there is a rule of thumb for resonant transformers where the weight of the primary and secondary should be equal. In other words, equal mass. I can only imagine the chokes weight will be relative to the mass of the transformer also. I would guess equal mass for all four coils?

For finding resonances in the transformer only(first) use a low input power, say around 2 or 3V, and one light on each side of the transformer. The lights should be chosen for the appropriate power levels for each side. Using a sweepable signal generator as input, sweep the frequencies slowly while noting the brightnesses of the lights. Measure voltages and frequencies at those most brightest and dimmest spots. After your comfortable with finding resonances with the transformer alone, you can add the chokes and see how it changes the circuit.   You could also use Avramenko Plugs to test the secondary in some imaginative way. Otherwise you will need a scope with HV probes.

Thanks for that tip!
I'll be looking into getting an inductance meter, as well as sitting down with some formulas to figure some things out, and i'll never be able to get a good capacitance reading off of the tubular array so an insulated resonant cell will have to come soon

Are you sure you have the same signals? Pulsed input on the primary and pulsed output on the secondary? If you have 10 times step-up when input is 10V you should get about 100V on the secondary. Is this measured on open terminals at the secondary? Check both signals on a scope.

I have been busy with my ESL transformer. It has 125x step-up in a 300-20kHz frequency range. When I use a 2N3055 transistor, connected just as in the patent circuit schematic on (TX1) and input a PULSED voltage amplitude 50% duty (0-10V) at 10V@300mA on the primary. GATED at 50%. When measured on the secondary I get about 1kV in 1kHz to 19kHz PULSE range (sure it looks like a PULSE). So the PULSE TRANSFORMER works here...also when I connect a FL lamp, it is ON at the HOT+ and OFF at the GND so I think I have unipolar GATED PULSE signal.

But now... The primary resistance ESL coil is 1ohm 300mA is measured here (because of GATING). Secondary resistance is 3kOhms!
When I connect a diode,choke (BIF1 2298 wound 0,15mm BIF2 2298 wound 0.15mm 4cm 12 cavities) and WFC I don't have enough current from the secondary into the chokes. I measured about 80V@2mA (10V@300mA primary). When I disconnect the WFC I hear the chokes buzzing and the FL lamp is on (connected to the HOT+ ESL) I measured about 1kV@2mA (10V@300mA primary).
So diode is working...what is going on here?

How do we match the impedance with the secondary (ESL) and chokes and WFC to get some current through the WFC to start polarization process. Where Stan has about 25mA without resonant action and 1-2mA in resonance?

Also it maybe a fact that all the coils should go on the same core to have max. reusable EM fields. So my ESL won't be the correct approach for HV. The question is how to make a PULSED TRANSFORMER for a frequency range and not one fixed frequency?

Simply put , that is a contradiction .

If you want high step-up , need many turns on the secondary , if you want a good power transfer you need high inductance .

But high inductance means low amps at high frequencies . The secondary impedance is huge , so even direct shorted secondary with an ampmeter you will get a few milliamps .


The same would be true with an alternator @ 5 Khz , you just couldnt get any amps out of it because those windings are in the circuit .Lets say you cancelled the Inductance with some series capacitance , then you will face loading problems , transformers are rated for minimal power . This is the law of electricity , there can only be compromise .
