LOOK REAL CLOSE at the Cores.  It sure looks to me like they were removed from some kind of Video Tape Recorder Cartridge.
It looks like SM REMOVED some of the Tape from the CENTER to make an inexpensive Magnetic Core.
What kind of Video Recorder did the tape come from?  My wild, wild GUESS is an EARLY VHS Prototype, a Seismograph Recorder, or an old TV Studio Video Recorder.
WHY, because the STRANGE frame base on the bottom is VERY, VERY SIMILAR, but doesn't exactly match, the inside of modern VHS tape cartridges.


Proof 1 = The white plastic disc UNDER each core looks IDENTICAL to the Toothed White Disc in a VHS Tape Cartridge.
Proof 2 = If he DIDN'T make the cores from a Tape, then WHY did he place a White Toothed Disc UNDER each Core?  It doesn't make sense!
Proof 3 = Teeth all around the outside edge of the white disc, just like in a VHS tape cartridge.
Proof 4 = He filled the center with epoxy to keep the loose tape from UNRAVELING or UNWINDING.
Proof 5 = The Exterior DIMENSIONAL SIZE of SM's Cores looks IDENTICAL to the size of VHS tapes (see bottom photo).
Proof 6 = If you Disassemble a VHS Tape Cartridge, there is an Identical WHITE DISC (with teeth) under the tape.
Proof 7 = His Model 1 Unit has an identical looking core in the center.  SAME notched white disc, same epoxied center, same frame base, etc.
Proof 8 = SHARP EDGES on the core just like a video recorder tape has.  Many, BUT NOT ALL, Ferrite & Iron Powder cores have ROUNDED edges (see photo below).
Proof 9 = SM was employed in a store that sold video & audio sound merchandise, & had easy access to recorders & tapes.


SUMMARY:  If you still doubt, then answer this question.  WHY would SM go to the TROUBLE of Disassembling VHS Tapes, just to place the WHITE DISCS UNDER
                Ferrite, MetGlass, or Iron Powder cores?  PLUS, why would he fill in the centers with EPOXY?  It wouldn't make any logical sense!

If you listen CAREFULLY to the Jack Durban interview, he tells you EXACTLY what those are.  No guess work involved.  I will give you a hint... they are part of the "output".

Do you mean : part of  inverter circuit ?

I only post my stuff 1 time.  If people heed that's nice.

If they just don't care, then that's fine too.

For what it's worth - not exactly about TPU, but has a lot in common with its principles, I think:
http://www.tuks.nl/pdf/Reference_Mat...NAL_FIELDS.pdf
I don't think he's got the bar magnet fields quite right on page 5, but it's a minor mistake, and side issue in the overall scheme of the paper.

I think your graphic of the toroid is onto something important, and no, not the material of the core, that might actually be irrelevant.  Before you scoff, think about this....

That little tiny loop of wire connecting the left side and right side coils, which I have never seen before in Marcus images, but now that you point it out, it looks right, and falls right into place with something I've been thinking about.  That little loop of wire connecting the two coils CONNECTS THEM IN OPPOSITE DIRECTIONS, like a Ceducious coil.  No, a Bifilar wound in series is not the same thing. 

A Caducious coil is not good for an input coil to a transformer, because when electrical energy enters the coil, the two halves electrically oppose, and the dual induced magnetic fields fight each other inside the core, and the energy is nullified, and no energy enters the core.  However, used as the output winding of a transformer, the Caducious coil, if wired in a specific way, will provide an output of electricity, and the two opposing BEMF forces will cancel each other.

Wired what specific way?  Here's the catch.  The center tap, that little loop of wire between the coils, must be one of the two AC output terminals, and the two outer ends of the coil must be connected together and used together as the other AC output terminal.

STOP. LISTEN.  You might think this wiring will produce no electricity, as the two induced currents cancel each other, but this is NOT the case if you used the center tap as an output terminal.  Each half phase of input magnetic energy through the core, will cause a current flow in both coils that come together at one end of the core, and feed OUT from one connection, and in from the other end.  And during the other half phase of the cycle, magnetism will reverse, and induced electricity will reverse direction too, and still produce electricity in the other direction, because they are wound opposite, they feed electricity opposite.  The electricity flows out, through a load, and back in the other side of the core, then reverses. Current flows, and the two BEMF's Cancel each other.

It's like a reversing, half cycle induction rectifier. HCIR   No commercially available transformer I have ever seen has an output winding wound like this.

One other catch, the two output halves MUST be equally loaded or the two BEMF's will not completely cancel, hence the connection of the two outside ends connected together. One load resistance across both coil halves.

It's hard to say if this is what Marcus has here, there is some piece of something in the photo originating near this little loop, maybe it's the output connection????

Concerning the core.... if the BEMF's will truly cancel each other, it doesn't matter what the core is, other than for deliverance of magnetism in the first place, permeability & frequency response.

Merry Christmas

In fact, based on that thought, I wouldn't be surprised if the big outer ring is the input core (The Primary).

It is a CHOKE and nothing more...sigh.

You will never figure out the how and why the TPU works looking at pictures.  Only by reading SM and then taking it to the bench.

P.S.  I need the assistance of a chemist, is there one still here at OU.com?  Thanks!

Cheers,

Bruce

Saintsnick:

Sorry, but you cannot discuss electronic circuits like you are summarizing the plot from a movie in 10 paragraphs.  It's simply pseudo electronics talk that upon closer scrutiny usually makes no sense.  If you want to discuss what you are talking about then post a schematic diagram and some electrical timing diagrams showing the waveforms.  Show your input signal and input power and your output signal, the load, and the output power.  Then start a discussion about your circuit.  Without a schematic and some timing diagrams that show what the circuit actually does there is no substance to your prose and it is mostly fantasy talk.  If you are sure of yourself and your convictions then you should be able to do it.

What happens to most people is they discover that in fact they can't make the transition.  I am fairly good with electronics and circuits and I can't make head or tail of what you are talking about.  So the challenge for you is to make that transition from "just talk" to something real: a schematic, timing diagrams. and a discussion that references the schematic and the timing diagrams.
