High Voltage Circuit (VIC)
Hydrocars:
do not forget stan center tapped his secondary also.
Yes, you can read high voltage across the cell when no ground is present. Google isolated ground vs ground, Not sure what it does myself but it has an effect.

Center Tap creates opposite voltage potential +POS and Tap (secondary neutral) and -NEG from the secondary transformer windings when windings are equal, necessary for charging the di-pole through the chokes.
When HV present over WFC, then there is perhaps no equal opposite voltage potential. The transformer and or choke are not equal wound? Potential is ZERO?
Seen from Tap there is +HV and -HV?

Webmug I think you are right on track!

My new step-up transformer 2x90 wnd primary 22AWG / 2x1000 secondary 26AWG center tap.
Choke bifilar (22AWG 850wnd and 26AWG 850wnd)
50 s/s rods into the two coils as core.
I got HF over the WFC cell and little bubbles are created, nothing serious! ;)
When I connect the FL lamp between +WFC and -WFC it does not glow, when I put my finger in the middle of the FL it does glow from finger to -WFC and +WFC connections. When I let go it stops glowing. When I only connect the FL to the +WFC and put my finger on it in the middle it glows from +WFC to my finger opposite with the -WFC connection.
Looks like i have NEG and POS voltage over the FL lamp.
It is obvious that my chokes are not restricting current at the moment. That's what I have to figure out now and get resonance in the choke first. When I know the resonance frequency and see it on a scope I make a step-up transformer with the same resonance frequency and fiddle with the PWM signals (duties, gate, pulse) and input amplitude voltage and get the total coils in resonance.
When I have that figured out, I have to match the impedance of the total (WFC connected) system. I think then the 430F s/s wire is needed, to match the WFC capacitance to get WFC and choke in resonance. I hope the gap size of 1mm (1.524-0.254mm) is small enough to match on. A pickup coil can also be used, to see if the system is in resonance, when not frequencies must be altered.
Basic first thing I do is fiddle with a choke right now, then we go a little step further. ;D

I'd suggest a smaller simpler VIC to play with first, stan talks about more than 1000 volts with only 100 turns on the chokes, it's not a step up ratio that makes the voltage, it's inductive reactance
You got 90:1000, is 1:11, so at 12 volts you get 133 volts, then into your huge chokes, but if your chokes are not neat the the wire wont lie exactly next to each other and be the same length, would be must easier to play with 100 turns than 850!!
You could try
P: 200 turns
S: 600 turns
Choke 1: 100 turns
Choke 2: 100 turns
These are the numbers from the fuel gas patent
sounds fun though :)
