Abstract
A control circuit for an electrostatic machine includes a current source or sink, an inductor, a switching network coupled between the current source or sink and the electrostatic machine, and between the inductor and the electrostatic machine. A controller is configured to automatically cause the switching network to connect the current source or sink to the electrostatic machine each half-cycle of a periodically alternating polarity. At each polarity alternation, the electrostatic machine is isolated from the current source or sink for a first period of time. At each polarity alternation, the inductor is connected to the electrostatic machine for a second period of time while the electrostatic machine is isolated from the current source or sink, and then disconnect the inductor from the electrostatic machine.
