Bob Boyce TPU thread

Thanks Bob.  Never hurts to ask those odd questions.

@  Bob B.
   Down to the wire on my controller so need to ask what amount of phase shift would you recommend as the upper limit? I would like to go ahead and install the shift circuit on channel 2 and 3 with a cut out switch to disable it. thanks

Bob,

I have a few questions for you if you don't mind.

1.) Is the attached core connection diagram correct?
2.) I understand that the bias supply controls extractable power out, and that it should be 160VDC.  What amplitude should the primary coil pulse signals be set to?
3.) I have heard on some of this kind of technology that voltage reversals in the primaries kill the effect.  Is that true here as well?
4.) What base primary frequency (ballpark) will a coil like this operate at?  Or is it dependent on the load and individual core?
5.) With regards to the magnetic bias, I just wanted to verify that I can pulse the magnetic bias coil without killing the effect?

Thank you.  I know it's a lot of questions--I have been thinking about the TPU for a while, and would like it to work on the first try!

@ thaelin

You will only need +/- a fraction of a degree, but I would opt for a bit more. +/- 1 degree would be more than enough.

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.

Edit: You may want to eliminate capacitors on the toroidal winding side of the chokes, C3 for the LPF in your drawing.
