Abstract

Abstract

High voltage pulse capacitor is the most extensively used devices in pulsed power system. According to the technical requirements of pulsed power system for the charging power supply, a set of bipolarity DC high voltage charging power supply, with output voltage of ±0.5 kV−±10 kV and maximum average power of 3 kW, has been developed. The charging power supply adopted the integrated design of the control circuit and the high voltage output circuit. The problems, such as the imbalance of output voltages of positive and negative polarity, the conduction of the sample and the control circuit, have been solved by means of isolation, shielding and protection. The volume of the charging power supply was reduced, and the robustness, reliability and electromagnetic compatibility were improved. Multiple charging power supplies working in parallel can work reliably under the complex electromagnetic interference environment stimulated by the pulsed power apparatus with the energy storage of 18.3 MJ.
