How the VIC Works - IMPORTANT!

dudes,

listen to my 2 cents.
I am winding my vic replica and i made many drawings.
As an electronic engineer from education , i can tell you that the secondairy coil and the 2 chokes can be seen as 1 coil.
The wfcell sits exactly in the middle of that coil.
Like if it sits in the middle of a battery or magnet.
Some kind of neutral place or whatever.
Think about what kind of magnet field is in the middle of a magnet where plus and minus meet....

With all due respect, I'm in discussions with an electrical engineer.  You're also not taking into consideration the reference point that Meyers puts into the VIC circuits, something an electrical engineer would recognize.  And assuming that there are two cores, it will not necessarily operate the same way.  Not to mention the coils are wired to oppose current flow with each other.

From what I can see, we need to stop looking at the VIC in a linear fashion.

About that second core.  Think about where the first resonance is going to happen.  We give a pulse in the primary and the L2 coupled to the primary becomes energized developing a voltage potential across it.  As previously stated, the voltage is now also across the L1 and secondary which are in series and together are parallel to L2.  Because there is a voltage now across the L1 / secondary, a field gets created on the second core.  A resonance develops between L1 and the WFC and a frequency develops on the secondary core.  How can we use this?  Oh, the feedback coil!  With the feedback coil on the secondary core we now have the ability to detect actual resonance between L1 and the WFC distinctly separate from the primary core and feed that to the PLL!

I suspect that could be why the L2 is variable and not the L1.  L2 needs to then be physically tuned to match reactance with its side of the WFC and the resonant feedback coming from the secondary core!

Well Ts i can tell you i just found something really interesting...
i wold say to forget this diagram they present for the moment and stick to meyers diagrams...however using this two core coils dividision...

 i would tell you that you should consider it as a transmission line...

Well Fabio, I already do.
I used to work for an electric utility.  And the electrical engineer I referred to above was the president of that utility.



I believe I already indicated my concern about the flaws in their interpretation of the diagram in that video link.  I included it mainly to demonstrate the dual core approach.

basically i'm trying to identify the modes of oscillation of the coils.... and how this would be different than a simple transformer..
I'm shooting the frequencies to it and analyzing voltage current and frequency for all possible configurations...

What I have found in simulation is that the combined sum of inductance in the whole VIC must be accounted for in the resonant property of the WFC.  Whether this is true in application I don't know,  but in simulation, I achieve a 15kV charge on a 702 pF cap using a value of of 721.65 mH on the coils on the secondary core at 5kHz and a gate pulse of 75Hz.  The L2 on the primary core likewise has a relatively low inductance.  Higher inductances on the coil directly coupled to the primary core seem to produce lower voltages.

Ei: the resonant frequency for a 702pF cap with a 1.44 H coil is 5kHz.  According to the simulation to get high voltage on the cap, the total inductance of all the coils (and using the mutual Inductance value from the primary core, not the L2's inductance value) must be equal to 1.44H.  And the L2 main inductance must be lower to get a higher charge on the cap.

Keep in mind that I am using the format of 2 cores where the L2 is coupled to the primary and the L1 is coupled to the secondary.

I will add that I have not been able to confirm this in application yet.   Awaiting some parts to fix my WFC.

Ts i think it has more to do with the length of the line... the cell should become as charged a very high resistance...
