Grumpy and others.
To start with STEAP and the SM TPU are one of the same.
To realise before anything you need to understand how this works. A full blown working diagram so as you just copy it is not my idea of 9 years of investigation. What I am going to do is tell you how it works, and what it is in it's parts.
First off the circuit on the brown paper drawing of the coils IS CORRECT, what you need to realise is he was drawing a top and bottom set of coils.
These coils DO not buck as it would appear because the centre taps come back on themselves in the drawing. This was for ease of drawing so as the connections can be seen. So you are looking at a top and a bottom toroid, but it could have been drawn with all the coils going in one direction.
The loops in the centre (2) are through all coils together, and were drawn like that so as they can be seen as seperate coils to the over wound coils. These loops are in fact a bifilar coil with their ends shorted so as to form a capacitance with next to no inductance. This acts like a SOLID ring, or core, inside the external coils. The centre of the TPU is JUST A NON METALIC FORMER (cork or the likes).
The TPU heats up OVER TIME, why? because the coils over the top pass multiple positive pulses in one direction through two coils (a and c coils).
The a, b, and c coils are wound as a trifilar coil, all in the same "direction", very important. Why is this important! well these pulses have varying amplitudes, like a sine wave but ALL positive. What happens if you have a MOVING magnetic field across that core! YOU WILL INDUCE A CURRENT INTO THAT CORE, eddy currents, over time it will heat up, not instantly like in iron, because it is copper, BUT it will heat up.
When you induce the current into the "core" it will produce an equal magnetic field going OUTWARDS towards the external solenoids. This is like an induction heater, but here is used a moving magnetic field (DC), and not an alternating magnetic field. The fields are perpendicular to one another, SM did not say exactly, only that "they" are perpendicular. The "b" coils wound as part of the trifilar, are not part of the moving field inducing into the core, but the collectors of the perpendicular field from the core, which was created by the huge circulating current in the core. So SM's collectors are not the core, but the "b" coils. IT IS A DC LINEAR GENERATOR, the trick is how it becomes OU and how it is fed back into the "front end" if you can call it that. The output is from either side of the "a" mosfet as shown on the drawings, the CMC is a separation of the DC generator and the multiple pulses of different amplitude (a filter).
The core is important, and is where the gain (to use SM terms) comes from, NO KICK and it will not work. There are only two input frequencies, not three, B is a switching GROUND from the collector to the A and C mosfet drains, B switches either with A or with C, A and C are never ON together.
Other words of SM:- When you cut the supply, the electrons have enough momentum to hit their target!
