Solid state TCs and vacuum tube TCs are essentially just that. You could
of course try to build a true mechanical generator, but I'm sure that'd be
a lot more complicated than a simple SSTC or VTTC.

In some of Teslas patents there's described a dual system with a rotary
switch, which generates a "high frequency" (high... hah... ;) drive to two
resonant systems. Basically DC => HF AC. IIRC you can find the patent
at least on, umm, Keelynet (just ignore the free-energy stuff there).
Probably available somewhere else too.

Pardon my ignorance, but are magnetic amplifiers still in use? I've a book
about them and how to use them in switch mode regulators, but that book is
from 1960 or so (almost antique ;-), and they sure seem superseded by
power solid state devices nowadays... ?
