@ Woopy
have you tried the film on an inductor with and without core

Hey Loner

Can you specify which link? 

Im winding my primaries for my 2nd multicore inductors.

Should have pics this evening.

The first is a mod of the first example of 2 cores. Primary wound on first core, secondary wound on both cores.
The second core is larger than the primary wound core. As the pdf suggests, there are inductive interactions.

But if I can get more of the induced field from the secondary coil into the 2nd core, then more current can be had from the secondary vs what we normally get in a normal transformer config.

The second multicore inductor is of the last example in the pdf.

3 cores, each with individual primary windings connected in series, and secondary wound on the 3 cores as a whole.
Just a simpler way of going about it as shown.  ;]

What Im hoping for is to use the primary as the BC inductor, but also collect from the secondary. Being that the pdf claims that the secondary current flow wont affect the primary oscillations, then the primary should still do its job as a BC inductor. And we can add what the secondary produces to the result of the BC.


Like transferring from 1 cap to another, 1 100% transfer, and get work done or store energy from the secondary.

Should be done with the second inductor in a couple hours.

hey Mags
looking forward to the pics, been winding a few myself here lately,Iv been thinking of concentraiting the magnetic field into a small area, kinda like a pancake coil this is what comes to mind

[Magluvin]

Heres the pics. Ill be trying them out tomorrow evening.

Happy Easter!

Supposedly with the first one, if the secondary is open, the primary inductance will be of the primary coil and the small toroid core. I have a spacer so the primary and secondary cores dont touch.

If we short the secondary, the primary inductance should go up, according to pdf. This will decrease the input current. So if we have a load on the secondary, the primary input will lower.

The second pic is a way to accomplish the last toroid example in the pdf.

I went with 15 turns on the primary each core. 45 turns in series on 3 cores. Supposedly when the sec is shorted, each primaries core gets the 2 others added. Its like a scrambled egg generator. lol.

But the interesting thing from the pdf on this one is, the more cores and primaries added in this fashion, the secondary voltage rises. Not the norm. Says the pdf.  ;]

So we shall see wut is uP.    Would be a nice simple solution if it is what it is.

And all the little switches and diodes, and batteries, etc will have a greater purpose.  ;]
