Thank you for your insight on the matter.
As you said, one of the important factor is to get the magnetic field
from the magnet all contained in the core. Which is why (as far as I
know) Metglas core should be better. Because of the huge magnetic
permeability of these kind of core. As a matter of fact, once the
magnet was in the core, I was unable to remove it from there (without
damaging the core)
Still, Having read the book, and a few other things, I still think
that some information is missing/misunderstood. As for myself, if I
knew everything (about the meg ;) I would not be asking for some hints.
I have been told that the magic would be happening when the core start
to saturate. Someone else also pointed me out that my magnet could be
too powerful. I seriously doubt that. The magnet has an area of
967.74mm(square) with a field density (Beta) of 1.3 tesla. The core
saturate at a field density of about 1.4 -1.5 tesla (core complete
saturation at 1.54 tesla) also, the area of the core is
1102.5mm(square).
so, when you have no inputs, the core flux is about 1.3Tesla right in
front of the magnet, but elsewhere, it is more:
(1.3 * (967.74 / 1102.5) ) / 2 = 0.57055 Tesla
*** note, the whole thing is divided by two because the flux separate
between the thow "branches" of the core ***
Anyway, to prove this "partial saturation" thesis, I'll need some
better electronics, becaus mine is burning when the back emf from the
input coils create voltage over 100Volts... (wich is about 30 volts in)
I'll try to get something that works at 500 volts and I'll tell you
how it goes. With that kind of electronics, I'll be able to reach the
optimal +70 Volts that Bearden was talking about.
