No B-EMF bi-toroid transformer Part 3

Hi there,

Here i try to couple the primary coil core physically to the main core, to see if this increases efficiency of the system.

It is based on the Thane Heins Bi-Toroid transformer. It seems to have NO back coupling from the secondary coil to the primary coil.

So no B-EMF force to be overcome in the primary coil.

Still thinking of ways to increase efficiency here.
So any ideas? Let me know.

If you would like to sponsor me, so i can manifest all the ideas i have, and share them with you, donate via PayPal :
