Sorry, didn't bookmark, but when you search for "bi-torroid" on youtube, they appear on the first page. I think one was by woopy.


BTW. it's a shame that noone ever commented Stoyan's PDF, (prev. page), he had some interesting ideas, but also made me think about what's really going on inside a core when 2 paths share one piece of iron. Can they use parallel, opposing paths? I guess so. They can do it with their own path (in the heart of a finite core the path flow is reverse, compared to the areas near the core surface), so why shouldn't they do it when the back MMF of a secondary comes along? Well, maybe off topic. But in fact I think this is why the BTT needs a good saturation in the primary core: No place for further paths.

Here a schematic, (Maybe you can use for lazer cutting).
Ideally:
C=(2*B)+(2*A)+E
Outer dimension = (2*B)+D
Inner dimension = D

For a good Heins effect B >> E (maybe 2 or 3 times...).
Regards.



I was amazed that there was a people already think of this, a simplified thane heins transformer. I am currently making this out of standard EI core. I will post a picture when I finish it.  :)

Magnetic amplifiers predate Thane Heins by over 100 years.  As materials and other competing technologies have evolved they come into and go out of vogue.  They have never delivered surplus energy.

Im still believe that all thane heins said was true. We will not know it untill we test it... Im finished cutting the center leg. I cut it one by one using metal scissors. The center leg width is 1/2 of the two adjacent leg. Next, i will make a bobin using a plastic bottle.

You should finish your experiments.  If nothing else you will learn some things.  You could also read up on magnetic amplifiers.  It may help you to better understand what you eventually see when you run your experiments.

 Are you talking to MEG? Where can i read about magnetic amplifiers? If i failed in this thane heins replication i will turn my transformer into MEG. I will completely remove the center leg then i will replaced it by a magnet.

See what you can do with an alternate path design, picture of it below:

Good design but i have no more material to do what is in the  picture and im content on what im doing now because i like a much simpler design. :)

I think in this picture when the flux flow from white core to black core, eddy current will produce if using a laminated steel core.

Fluxes don't mix between cores. What is created in the black core by secondaries stays there and bypass the primary. I tried putting air gap between white and black cores but it had no effect compared to case where cores touched. Normally if you form close loop using iron while coil is energized you will hear and feel the vibration. In this case absolutely no effect occurred. So, in my opinion they don't mix.


Of course you do as you please, I just wanted to inform you about this possibility since you are playing with this.

No, I am talking about magnetic amplifiers, often referred to as mag-amps.  These are devices that control the flow of power by partially or fully saturating under the influence of a control current and thereby passing a much larger load current once saturated.  Google mag-amp.

Im sorry but i dont get your point whats important here is the primary must high reluctance while the secondary has low reluctance. If you make an airgap between two core, the flux from the first core wont flow to the second core thus the flux will only flow to the two thinner leg of the first core. So the primary and secondary still has the same reluctance. Increasing the area of the core reduces the reluctance so the two core must close together in order to reduce the reluctance in the secondary.

A much better design is split the two black core in to halves then put the two into the sides of the white core so the flux can flow more easily into the black core.

Its just a power amplifier like transistor except the input was dc controlling the ac output.
