Hi Ken
The BMM3 and other 3 coil systems never produced the sorts of
resolts that I had hoped for, there was also so sort of
resonance set up in the control system as I kept blowing variacs, so
I`v gone back to the more convenoinal coil setup.
wow s.s.t.c magnifiers now thats a black art if ever there was one
but there are a few guys in the UK that my be able
to help, if you look on the UK coil builders list on my web site you
need to get in contact with Alan Sharp, Richi Burnett
or Steve Conner these guys live and breath solid state coils, I seem
to recall the Alan did build a SSTC magnifier

Greetings-
I came across your Web pages, particularly the one on your "New BMM3
Magnifier coil". I've been working on a new s.s.t.c.,
conventionally doubly-resonant, but have begun to feel that a
"magnifier" scheme would be better for me. Currently I have 2
secondaries available from my previous s.s.t.c., both 12" diameter,
resonating at 100 & 130 KHz, and also a mains-driven H-bridge--plus
drivers, timing, etc.--using IGBT "bricks", checked out & ready to go.
The "magnifier" I have in mind would not be resonant, being merely a
matching transformer between the H-bridge and the bottom of the
secondary. Feedback to initiate & sustain oscillation would be
taken from the (resonant) secondary, either via a 1-turn pickup coil
or perhaps from the ground-return of the matching-transformer's
secondary. Thus I would end up with a singly-resonant system, as I had before.
How did your BMM3 work out? The photos look good! Any suggestions
along this line would be appreciated. And I'll be happy to provide
more details of what I'm building.
Thanks,
