摘要：A polarity reversing circuit having energy compensation may comprise a firstinductor connected between the first electrode and a negative terminal of a powersupply. 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 inductor so that thecathode of the diode is connected to the first electrode. A second capacitor and aswitching device are also connected in series across the first and second electrodes. Asecond inductor is connected between the switching device and the anode of the diode. Abi-directional converter is connected between the power supply and the second

capacitor. The voltage polarity between the first and second electrodes may be reversedby actuating the switching device to switch between a non-conducting state and aconducting state. The voltage polarity may be returned to the normal polarity by againactuating the switching device to switch it from the conducting state to the non-conducting state. A bi-directional converter transfers electrical energy between thepolarity reversing circuit and the power supply to compensate for variations in theamount of energy reflected by the electrodes during operation.
