Abstract:
The principles of the classic rotary Wimshurst machine,
which produces dc high voltage by regenerative electrostatic
induction, are used to develop a new alternating high-
voltage machine. This device has no electrical inputs
but can spontaneously produce either dc or three-phase ac
high voltage, depending on external connections. The
machine constructed by the authors produces voltages in
excess of 18 kV which frequencies of operation up to 2 Hz.
Improved design can extend the voltage and frequency
operating ranges. Analysis is extended to include multi-
phase, multi-frequency operation by modeling the device
with a distributed equivalent circuit representation. The
natural frequencies of the system are calculated where it is
found that many overstable modes are present.
