Abstract
A circuit for reversing a voltage polarity on a first electrode and a second electrode may comprise a first inductor connected between the first electrode and a negative terminal of an external power supply. The positive terminal of the power supply is connected to the second electrode. A diode and a first capacitor are connected in series across the first and second electrodes so that the cathode of the diode is connected to the first electrode. A second capacitor and a switching device are also connected in series across the first and second electrodes. A second inductor is connected between the switching device and the anode of the diode.
