正负双极性直流高压充电电源设计北大核心CSCD

高压脉冲电容器是脉冲功率系统中应用较广的储能器件。根据大容量能库型脉冲装置对充电电源的技术要求,研制了一种输出电压±0.5~±10 kV可调、最大平均功率约3 kW、双极性一体化直流高压充电电源。设计上采用控制电路与正负双极性直流高压输出主电路一体化方式,通过隔离、屏蔽和保护措施,解决了目前双极性直流高压充电电源存在的正负极性电压不平衡、采样控制信号与高压地未隔离问题,减小了电源体积,提高了电源的鲁棒性、可靠性和电磁干扰能力。100多台充电电源在18.3 MJ脉冲装置中同时运行,在复杂电磁干扰环境下可靠稳定工作。

Design of bipolarity DC high voltage charging power supply

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.
