not yet....but if you understand the term bifilar and read teslas patent on bifilar inductors and see aaron m's work and notice the dot orientation on the vic schematic then you will realize that john's connections are in fact correct....your theories apply towards alternators.....but not solid state.

there is only one bifilar coil here.

on the alternator there are multiple ss bifilars.

also johns windings are correct for bidirectional primary.....no overcomplication here.

My question is how are we gonna get the transformer to work in an unipolar way ??

i have already messed around with this concept many times.....regardless if the transformer acts unipolar or not the diode makes it unipolar......there are no problems.....it would just be "IDEAL" to get a unipolar transformer......but not every transformer is perfect.....so no worries it works the same either way.

the electrical steel core forces it to be unipolar, this is noted in the TB, i have no idea what is going to happen with the ferrite cores, but i hope they work

the ferrite cores will only slightly reduce the voltage amplitude since it is not perfectly unipolar and more so ac "friendly" like an audio transformer.

remember this one:
(instead of 0-100v, the transformer creates -100 - 100v (for example) )

without the wfc, it is a tesla bifilar

but as always, I'm showing nothing that is new to ya.

If you realize that the 100V leg of this Tesla's Bifilar Coil Design is connected to the North side of the secondary and the OV leg is the Isolated Electrical Ground connected to the South end of the secondary then you would know that this is exactly how Stan's coil is designed.  The only difference between this and Stan's is that Stan’s secondary also shares the common core with the primary and bifilar chokes.
