Regeneration and the Toroidal Power Unit

[bob.rennips]

TPU2-4A - I'm certain this is a fluorescent light starter. See attached composite image.

This is a quote from how stuff works:

"The glow tube incorporates a switch which is normally open. When power is applied, a glow discharge takes place which heats a bimetal contact. A second or so later, the contacts close and provide current to the fluorescent filaments. Since the glow is extinguished, there is no longer any heating of the bimetal and the contacts open. The inductive kick generated at the instant of opening triggers the main discharge in the fluorescent tube. If the contacts open at a bad time, there isn't enough inductive kick and the process repeats."

As SM says you start off with one kick which then builds into many thousands of kicks. This is the ideal component to generate the starting kick. 9volt battery goes to the starter and then to a coil of fine wire (with say a magnet core) - the collapsing field generates the first kick that starts everything off.

hi Bob
I think youve mentioned that before about the fluorescent light starter.
untill now i was thinking the device had two 9 volt battery's one under the magnet and one where the starter is.
i have opend one up and does contain a bulb like bi-metal bulb and a capacitor.

The little device Marco asked about that is connected to ?

That is what used to be called a Top-Hat rectifier. A proud design of International Rectifier. It could be a garden variety replacable with a 1n40xx series or it may be an avalanche diode or zener. If it is connected to the top end of bif' windings of the same coil it may be a simple rectifier. Hmmmm.. that alone would produce some ringing if energy was induced from the core or another winding.

I'll just throw these two things out here. They are two different ideas I have contemplated for many months, and have mentioned them before (some may remember). Two possibilities for the makeup of the open TPU:

1) It seems no one has considered that this unit may be comprised essentially of qty 4 of the first 25W device SM demonstrated, that he pulled out of the case. I believe that the open device is quoted to have an output power of about 100W.

We see a few distinct similarities:
- There is a 1:1 transformer (the bifilar winding) (therefore, black ring in open unit would be ferromagnetic)
- Control/Collector coil set is capped by upper and lower metallic frame or plate
- Control/Collector coil set is wound 90? to each other as SM said, but in this case, looks more like a solenoid in shape.
- There may be more similarities...anyone?

One difference however, would be that the starter magnets would be placed on the Control/Collector coil instead of the 1:1 transformer as in the 25W device.

2) The black ring may in fact be the Collector coil, and the red bifilars the controls. This is more in line with how SM told us to make the device. The black ring appears to be continuous all the way around, but it could conceivably have an air gap...maybe, maybe not.

How is the potential tapped then you ask? The answer to this may be the secret to the entire device. One SM comment that has always really intrigued me was that "one must find the circuit potential in order for electrons to flow".

Look at a close up of the larger TPU where the fuse holders are at the back. You will notice a rather thick, black bar-type wire where the tape is cut away. Could this be the equivalent of the black ring? Maybe it is simply there as a structural component.

The 4 inner coils (well we assume they are coils) would then be the 1:1 transformers as in the 25W device.


The 25W device appears to be the simplest of them all. We just can't see any detail of what makes up the center part. I have determined however, that as I mentioned above, the upper and lower caps are in fact a sprocket of some type. If viewed closely, one can quite easily see the points, and the white silicone SM ran along them, presumably to prevent injuries. These caps are metallic folks.

Could this be the "bailing wire" he mentions in the video though? Bailing wire here meaning "thrown together with what was around", not in the literal sense.

Food for thought perhaps.

^^ interesting incites Z_P_E

i think #2 seems to make more "sense" .. lol .. i think the black frames might have 2 wires per ring ..

@marco .. the starter bit is pretty interesting
