Watched the video yet again and picked up on a few things. Stan definately mentions that the chokes magnetic fields remain intact while the secondary magnetic field is collapsing and current is trying to enter the series circuit but he says the magnetic fields of the chokes stop it doing so. Then it dawned on me, something I was thinking about when I built my last VIC.
What if: The secondary's current lags the voltage by 90 degree's (happens in a lot of inductors) and the choke's current lags the choke's voltage by 180 degree's. Would that not cause the choke's current to lag the secondaries current by 90 degree's?
Then when the choke's try to induce current into the series circuit the bias of the diode stops it?
You would have in phase series voltage as the first mode of operation then the secondary current as the second mode of operation being blocked by the choke's magnetic field then the last mode of operation what be the bias of the diode blocking current from the choke's.
The series voltage would of course follow the bias of the diode.
Just saying.

Actually, thinking about this, if the secondary current lags secondary voltage by 90 degrees then the choke's voltage is 180 degrees out of phase with the secondary voltage then the secondary current and choke current are 180 degrees out of phase. But another interesting point in transformers: You can create a 30 degree phase difference in the current and voltage of secondaries that have different step up and down ratio's on the same core. You can also use a variable inductor to change phase shift and if you can control the dc offset of the input it gives you all kinds of possibilities.
Another interesting point, in the NZ video Stan also mentions and points to the negative choke when he talks about the secondary current being restricted by the magnetic field of the chokes. Is Stan timing the phase shift of the negative choke so that secondary current cannot pass?
Also, i've just read a patent in which the author discusses doing this very thing in which he uses a phase shifted inductor to control current and voltage in inverter systems.
All you'd need to do is avoid the cross over points of the phase angles and just make sure that the current of the chokes lags the current of the secondary by 90 degrees. That would ensure the magnetic field of the negative choke would block any current path from the secondary.

Just a quick addition: Imagine that the three coils in the VIC are a delta configuration of a three phase series circuit with 120 degrees between each phase, for the system to work correctly, each current phase needs to be 120 degrees apart but if you cause one of the phases to be less than 120 degrees it might unbalance the system. For example, all three secondaries current lags the voltage by 90 degree's and each phase is devided by 120 degrees, if you made two of the phases lag the other phase by a few degrees less than 120 then the tming of the phases gets really screwed up, you'd end up with those two respective phases being choked by the other. I don't think that Stan's system is three phase because there is only one primary and three phase systems need three primaries but it demonstrate's how phase shifting can unbalance the current in series inductors.
Stan's three secondaries in the VIC are wired similar to the secondaries of a three phase delta transformer but the single primary causes it to be single phase and just additive secondaries or single phase series secondaries.
But imagine what happens to the current in such a series system as Stan's when the secondary coil is attempting to induce current into the circuit but is blocked by either both or one of the choke's magnetic fields? Then milliseconds later when the choke's also try to induce current into the circuit, the bias of the diode blocks it?
The primary see's no load across the secondary but the series voltage has already gone in the direction of the bias diode. Surely not this simple?

And by the way, in my last video in which I had 1000v on the cell, the two chokes were 180 degrees out of phase with the primary and secondary. The primary and secondary were in phase, wired in the same direction and on the same core leg. The chokes were wired in the same direction but were 180 degrees out of phase because they faced the primary and secondary just like figure 9 in Stan's technical briefing.
The odd thing is, if you placed them in phase with the secondary no voltage was induced on the WFC.
Personally speaking and from much thought i've come to the conclusion that Stan's has his chokes 180 degree's out of phase with the secondary and that current is also 180 degrees out of phase but I think the secondary because it is in phase with the primary has control of the initial process and is dominant at the beginning of each paired cycle. Like I said, the voltage preceeds all other modes of the cycle being 90 degree's in front of current, the second mode is the secondary current being blocked by the time delayed chokes and the third mode is the chokes being blocked by the diode bias.
It seems to fit together better than anything so far i've suggested.

Like thus:

any patent reference ?
