Thane Heins BI-TOROID TRANSFORMER

[lumen]

Hi Lumen,

You may be able to upload large files according to the tips I gave Broli on page 5, reply #70 of this thread. What app did you use to make these layouts?

@teslaalset

The simulation was made in Maxwell 3d. So far I have been able to make it operate in three different modes, all of which depend on the exact shape of the core. If I can pinpoint the reason behind the operation (providing we know which mode works best) then I will try to refine it and build a test device.

I think I have the animated gifs uploaded in general files.

Gents,
I am easily confused when I'm doing something I've never done before.
I am going to stick with "FOR MARY -JO"

practically a spec sheet!
Broli has a chassis Schem for this "Mary-Jo" design.
Monday I get going..............

PS
I think we need a moderator ,even if all the crap I post gets deleted I DON'T CARE!

It would be so NICE to do a build JUST ONCE ,the right way!!

Ist page 1st post, an ongoing updated "reference" of "progress to date".
Like the REAL world does it!
Organized ,up to date!
Specs
Suppliers
ETC...........

Not a Job for Thane [unless he wants to]

Broli??
Tes??
??
just Me [her moniker]

I agree!
If this is indeed a schematic that is already proven and the correct scale, then don't change anything. I am not sure exactly why at this time, but it seems in the simulator, even a small change can drastically change the overall operation.
Something as small as placing a radius on the corners (which one might think would help) can reduce performance by 50%. Keep in mind that this is based on the result of a simulator which can be based on operator error! So I agree, if you are building, stick with the proven design.

Lumen I think it's mainly because of the 3d aspect. A 2d model is already a big job on the cpu, so you can imagine the strain of a 3d model. What I find too bad is the lack of software that simulates an actual running transformer design where voltage induction is part of the simulation. That would save a lot of time.

In this design, why the outer toroid (core 3) is the same scale than inner toroid (toroid 2 and 1) ? The core 3 must be larger than other two ? I don't understand here.
