摘　　要：为了满足小型化、重频化脉冲功率装置在无市电供应环境下的充电需求,研制了一种紧凑型重频高压电源。电源使用30 V低压直流供电,分别采用初级储能电容和多模块串联叠加结构实现输出功率的放大和100 kV高压的输出;通过仿真实验拟合输出电压和功率曲线,进而分析了模块和整机的性能;然后对电源各器件进行结构设计并完成了硅凝胶灌封;最后采用两组充电运行实验测试了电源系统的性能指标。最终测试结果表明：电源能够对320 nF电容负载充电至100 kV;平均充电功率大于10 kW;充电频率1～10 Hz可调;实际电源装置的输出功率小于仿真结果,可能是由反馈电流信号纹波过大和组装的等效阻抗更大所引起。该结果验证了重频高压电源技术方案的可行性,并为研制更高性能的紧凑型重频高压电源奠定了基础。A compact repetitive high-voltage power supply was developed in order to meet the charging demands of undersized repetitive pulse power devices when working without regular electricity supplies. This power supply, which is fed by a 30 V low voltage DC input, uses a primary storage capacitor and multiple convertor modules in series connection to realize the amplification of output power and output of 100 kV high voltage, respectively. After the output voltage and power curves being fitted by the simulation experiments, the performances of the module and the whole machine were analyzed. Then, the structure of each device was designed and sealed with silicone gel. Finally, the performance indexes of power supply system were tested by two groups of charging experiments. The test results show that the power supply can charge a 320 n F capacitor to 100 kV; the average charging power is more than 10 kW with the adjustable frequency from 1 Hz to 10 Hz; the actual power supply output power is less than the simulation result, which is caused by the excessive ripple of the feedback current signal and the higher equivalent impedance after assembly. These results validate the technical design of the high voltage power supply and can provide experiences for building compact repetitive high-voltage power supply with better properties.
