I think also there is no U-turn allowed inside the toroid as this will cancel each other.

Since we can agree that the toroid is in fact a bucking field toroid with both coils in series as in bifilar. This leaves two wires from the toroid center that I believe are going and comming from the top and bottom ring ends. As it is a way to start the current flow to the tpu output. The output of the tpu is also providing the input return loop to the tpu circuit so this can explain the gradual current increase in the tpu.

@BEP

Thanks for mentioning bucking field. I have looked it up since last nigth reading up on many types of usages and have found this paragraph........

I am now very close to putting these pieces together and have taken something from Tesla's patents to see how this can fit together sort of similiar to what I have learned with the Erfinder Challenge.

Now if the bucking coil toroid is the coil of high induction and is assisting in creating a suitable charge on EM's capacitor, and the control coil is the primary, and the collector ring is the secondary, then all I need is a way to create a short circuit going from the feed source, through the collector/emitter of the transistor and going to the junction where the bucking toroid and primary are connected together. This will produce high voltage into the primary and I already know from tests that the way the control coil/collector windings on my current build are giving me good coupling potential, this should produce juice.

Since my control coil and collector are each wound from one continuous wire, I may consider changing the control coil configurations to see if this can increase amperage but I will not change the single wire wind on the collector.

From my observation of the FTPU circuit, there are three small capacitors, one slow blow fuse, one resistor, one transistor, two diodes and another EM type capacitor so it should not be too hard to figure out how to connect these. I would imagine a few of the small caps are used to pulse the transistor base, the diodes are there to isolate the emmitter side of the transistor and also provide a returning side for flyback to source. Anyways, that will be a good problem to have.

the total inductance is LESS not greater.

nice find BEP, the coil wire sure looks like it reverses direction, very interesting.

The total inductance depends highly upon the mutual orientation and the common core. Use of the term 'bifilar' would also require the core be conductive to a mag field. I think it is not.
Should the core be ferrous, current hitting the opposing coils would create more reluctance in the overall coil. In short during one part of the cycle it would make the coil act like it had a very high inductance. During the 'off' state the 'series opposing' flyback fields would be equal and opposite - net zero.
When you deal with multiple coils of any type you also must consider if they are series or parallel aiding, opposing or some variation of cross-field. I believe these two windings are a combination of series opposing and parallel aiding but only because I don't think the core is ferrous.
Another thing to consider is when you wrap a coil around another conductor (that coil wound so the net MF is near zero) you reduce the effect of CEMF in that covered conductor. In short - it makes current flow in the covered conductor not only faster but easier. Hints of cancellation and speeding the current flow?
None of that will happen with an iron core.
Connect one end of that outer wrap with one end of the inner flat coil and you have a Rogowski coil on steroids. Rogoski's are constant voltage output.
Add a second flat spiral inside with some clean DC on it. You wind up with North on that last coil pointing toward center and North of the outer wrap in a loop around the circumference.
I'm thinking when you have two perpindicular mag fields they will be less likely to have an effect on each other and this will cause a third vector. Of what? I'll not start the argument.
Just be aware the above has me understanding why the ampprobe was positioned the way it was for the highest reading.

Yes, I'm convinced these little toroids are just the first stage of a step-up TPU instead of a step-up transformer.

@all

I did another complete and closest sizing of the center toroid cores and winds as having the following as final dimensions. I even took a grab of the toroid and superimposed a 32 turn x 2 drawing over it and gave the line width of 0.0418" or 18 awg.

2.50" OD
1.25" ID
0.50" HT

So the ID is half the OD and the height is 1/5 the OD.
32 turns x 2 in series, one winding in reverse to the other.
The turns are 5 degrees apart.
Wire is 18 awg having a nominal diameter of 0.0418"

I have not been able to find any toroid core with such dimensions on the market. Nothing. They all have thinner core walls. The dimension ratio of 2:1:1/5 is really unique. WHY???

I know I am getting to be a pain in the ass about this but I believe the toroid is the center most important part of the TPU and having some concrete information of this toroid design will give us a better insight on the remaining functions. Especially for the FTPU since there is so little to the device.

Also, if this is in fact a two wire bucking toroid as BEP says, then besides the two black wires, there are two white wires coming out the center. What if there really is a horizontal coil inside the center toroid. That would explain the two white wires. Oh but they are from the collectors or the control rings. Maybe not. Maybe they are from an internal coil in the center toroid core structure that then goes to the collectors. But as long as we are concentrating on the rings, we're not thinking inside the toroid. And maybe that's the way SM wants it to look. lol

Next move, get an empty Teflon tape spool, wind it with a 16 gauge lamp wire having a thin insulation on it, wind 64 turns at 32 turns reverse of 18 awg mag wire and start doing more testing.

@ wattsup - Beautiful observations! You have much more patience with these images than I. Your hard work is roundly appreciated.

I did some intense reading last night about modern toroidal applications and manufacturing methods. Google will return lots of results from both makers of these devices and the engineers designing them. From these readings, I am inclined to agree with BEP that these are designed as bucking coils - the application is right, the appearance is right, and as you suggest these are probably custom-made for the TPU, explaining why there's no widely available version through retail.

The white wires are mysterious. Wattsup, the only place I might question your interpretation as pictured is where the winding does a half-loop and reverses in the middle - everything I read says that reversing the direction would result in zero net influence, or even slow things down. Instead, could the white wires be center-taps, to provide feedback or current reinforcement?
