Understanding electricity in the TPU.

Also in high tension lines they use aluminum. From what I know, they use it instead of copper for 2 reasons. 1 its cheaper, 2 its lower conductivity does not stand in the way of the high voltage used there. Or is there another reason aluminum is used in these situations. ?
Very cool Watts.

i torn down a pole transformer once to find no iron or steel...
just to see a alum core rolled like a ac cap.. with high tension on top of alum the low tension on top of that... and then alot of oil...
so i just figured they work on induction..
so you guys might be on to something with the alum..

Well here we go. My latest toroid yellow ferrite core.

Very interesting first test of many many to come. I will have alot of fun with this one but will build another one with a AL core.

What the core has to do is get energized by the primary then die as fast a possible. With the maximum extreme in the core from dead to full sat, the secondary will produce maximum output. You do not need a core that can accumulate saturation. Hence the gain in the TPU cannot occur in the Toroid because as the toroid would increase in gain, the spread between the maximum and minimum saturation point in the core will decrease, and that lowers the efficiency. The ferrite is doing this. It is holding in some of the past pulses. So it does not drop to zero saturation before the next pulse occurs. The Aluminum core should make a big difference since it will always want to go back to zero very fast, faster then ferrite. It just remains to be tested.

The toroid is the wick and the rings are the cannons.

So here is an image of my first test and result.

Pulse generator set at 2500hz, duty 10% at 3 vdc.
Output on the holding cap via a germanium diode is 7.21 vdc.

Already, I have not seen this before. When I short the cap, it goes immediately to 7.21 vdc. No .01 increments.

The scope is at Time/Div 20uS and Volts/Div is 0.5 v

This for me is a good way to start pumping up a TPU. lol

But this is only the toroid connected two primaries parallel and two secondaries parallel. Pulse enters from the left red and black to the primaries. Out is right with diode on negative. Just like this is was getting 4.6 vdc, but then I added another diode between the pulse polarities and it jumped to 7.21 vdc. You can barely see it.

This also works the same in the 5000hz range.

Man am I going to have some fun with this toroid in connecting it in many other ways. This is just the beginning. Then to add the rings and integrate some wiring logic based on the observed FTPU. The target with this one is 60 vdc.

Oh, bringing up the pulse voltage did not increase the output but lowered it.

Do you know what you can do with 7 vdc. I need a coil of high induction, two aluminum rings with 42 turns each stranded copper.

More soon.......

Added. My setup below is very similar to the Cook coils just a different wiring. Eventually, I will try mine with this wiring and see what happens.

@otto

Try putting a diode across your pulse source.

Hello all,

@wattsup

I dont need a diode, not caps, not resistors.....nothing.

It seems that you have fun with your coils but ..... Aluminium??? Very bad option as a core!

@otto

That is great to not need anything, I guess except coils.

I will let you know about the aluminum, once it is done and tested.

Keep well.

Well here we go again.

I am now starting the FTPU build tests slowly but surely.

The image below shows something out of the ordinary.

If I put that led directly onto the pulse generator at its setting of 10% Duty, 1.5vdc @90khz, the led will not light up at all. Nothing.

When I put the led on the output of Test 2 trial, it lights up plus the voltage also shows a 1.9 vdc maintained in the cap. This I have never seen before.

Also, trying to find a way to make the scope stay put so I can take a photo but it is very difficult. The frequency changes like a never ending wave shift slowly one way. As I catch it, it changes again.

The center toroid primary gets the positive pulse on one side to both primaries, the two negatives then go to each side of the outer ring and the negative pulse from the generator is at the center of the ring (or near - lol). The toroid secondaries are paralleled, one side going to the cap tank via a germanium diode, the other side going to the outer ring then to the other side of the cap tank.

This is crazy because the speed of pulsing is sooooo high now, much higher then the 90k pulse frequency and it shifts so I cannot catch it as a stable scope shot. Weird.

My next Trial will be with two rings and control coils. Then I will have to integrate a coil of high induction. Then the fun should really start.
