If you consider the testatika's horseshoe magnets as being used at
a minimum as diodes and the front disk as a variable capacitor, then
it is clear from looking at the 3kW machine that some components of
it can function as a charge pump.
An excellant explanation for how a variable capacitor and diodes can
be used as a charge pump can be found in
G.L. Usselman's US patent 2,413,391. In fact, I'd had the circuit
below in mind for a while but until I got a better understanding
from this patent, I had the current flow (and my understanding)
backwards. Thanks to James on the
testatika Yahoogroup for bringing up this patent.
Possible components from the 3kW testatika and where
they could go in Figure 1 of the patent.
