Hi Aaron,

That does sound interesting.  Please post any results on this project.
We are still working on applications of this principle here in our
group.  We have had some success recently by modifying transformers
removed from x-ray high voltage generators.  

Since either the control or the power may apparently consist of 2
windings as long a there is no net voltage induced into the control, I
wondered if the transformer removed from a small pole pig might also
work well.  Isn't the low voltage side provided with a center tap?  If
so, it would seem that this might be split into 2 at that point and the
same wired in series opposing so that the net fluxes cancel and the HV
side used as the control.

Any thoughts on this?

Carl Litton

Hi folks, I decided to join the party and try building
one of these.  It seems to me, however, that the
simplest way to make a big one might be to start with
a ready-made three-phase transformer.  Does that seem
reasonable?  If you're going for a turns ratio
(control:power) of around 10:1, then a 4160V/240V (or
close) 3PH transformer might be just then thing, yes? 
It would seem like there'd be no winding to do at all;
you'd use the HV winding in the middle for the control
winding, and the LV windings on the outer legs for the
power windings.  You'd have to disconnect the windings
first, since their connections when used as a
three-phase transformer would obviously be all wrong
for this application.

Hmmm...
