Understanding the VIC

[Hidden]

Seb,

Thanks for the drawing.  The probe is put to the positive plate only, I will not ruin my oscope by trying across the plates to negative.  It is accurate I believe.  The diode and mosfet speed are factors to getting higher PTP peaks.  I did get over 15kv for awhile but had a nice blue crackling short going on near the side of a coil.  When I fixed that it went to 8.5kv.  We need to insulate better for over 5kv
is what i am learning.

Ferrite is the only way to go.  All other core materials do not de-magnetize fast enough and give lower ptp voltage than ferrite.  I use eight ferrite rods in a staight balun inside three 1000' 28 gauge bobbins staight off the shelf for the secondarys and a 100' 21 gauge wrapped over the center primary in the middle of the three coils on the eight inch core.

TonyW,

I tested the continuity of my insulated WFC today.

Before I applied power to the cell I measured continuity each way (got a beep both ways).
Then I connected a 12VDC power supply to the cell for a few seconds.
Then I disconnected the power supply and measured continuity once again and only got continuity (beep) when the polarity of my probes was
the same as the power supply which was previously connected.

I think this is simply due to polarization, and the electron collecting at the positive plate. Not sure how long it would take for the relaxation to occur but I'm guessing at that point continunity would show each way again.

I just finished testing sebos extra diode on my setup.If my choke coils are on the same core as the primary and seconary,it doesn't work.
But if I have my choke coils on a seperate core, than yes I get half rectified unipolar pulses at the cell,but not the double frequency unipolar pulses.
More testing needs to be tried.Which brings me to another question,I'll post it in a new post here.

Wish I had a good oscilloscope to see what i'm doing here...

The diodes are acting... the blocking diode allow the pulse to charge the network and the switching diode close the blocking diode further for keep the cell from discharge.

The unipolar should work with the coils on the same core if the polarities are as showed, cause they shouldn't interact at all. Except by increasing the distributed capacitance of the pulse forming network which actually change the frequency of the pulses. Also it would be able to increase the frequency of the potential applied..
