1. Mostly correct. The common tie point of the 3 coil positives is fed through a low pass filter, similar to that you have drawn in for the HVDC bias.

2. Primary pulse potential can be 13.8 VDC, as in the hydroxy gas toroidal power system, or you can drive it with higher potential - if you have it available. Similar to HVDC bias potential, the higher it is, the more effect it has.

3. What do you mean by voltage reversals? If you are referring to reversing which lead is positive and which lead is negative, then yes.

4. I don't have any answer for you, as the frequencies used will be determined by the size and construction of your coils and core. Do you have a sweep generator?

5. The magnetic bias power supply leads should be filtered as well. While you may get some interesting effects by allowing modulation to pass through into the magnetic bias field, I have not tested this yet.

Please try to understand, most of my recent experience with the construction and use of these toroidal power systems has been limited to the hydroxy gas version, which is a very mild pulsed mode version. I have done a lot of testing of rotational variants, and much of that ended in catastrophic failure. This has taught me many things not to do. Primary lesson learned was to always maintain tight control over the operation of the system.

My Tesla radiant energy research and resulting experiments really helped me with this toroidal power system research, as I truly feel that they are very closely related.

Bob,

Thank you for all of that info!  In #3, you were correct, I was referring to voltage polarity reversals.

I am assuming you mean a function generator with the ability to sweep frequencies--yes, I have one built-in to my TPU controller.  I use it quite often to find the resonant frequencies of various coils.

OK, I have another question!

Would this circuit be a better choice to drive the primaries with instead of the usual power MOSFET / driver combo?

From what I can tell it would seem to be, especially with the 10ns pulse width.  With your three-phase experiments did you ever have almost zero input power like Earl is talking about?

If this is a better choice, then I can build one on a board that will plug in to my controller instead of the power MOSFET board.

Thank you,

Eldarion

Hi Eldarion,

In my opinion, the low-pass filter that I have suggested to keep RF out of the bias supply must have C3 at the TPU in order to keep the output power loop physcially as small as possible.  See my attached explanation.

@ Earl

You seem to be thinking transversely. Assuming that the primary load energy flow would be from induced phase differential from one end of the secondary to the other, which would be coupled to the load through both caps - as you show. Granted, there is energy in that mode, but that would only be a portion of the total energy available. Please try to entertain the notion that modulated longitudinal energy is induced into the secondary winding from outside, and into the secondary/earth dipole. Modulated longitudinal energy flows through C1, and through the load to ground. A capacitor at C3 would shunt a portion of that energy to ground, bypassing the load. Just ponder this alternative viewpoint.

I looked at the link and was confused a bit by the next post stating that it was the wrong circuit ;-) In answer to your question, my last test toroidal transformer was pulsed with about 270 mA average current @ 13.8 VDC on the primaries. This was total average current of all 3 primaries added together. Just keep in mind that it can take high peak impulse currents to create fast potential transitions.
