摘要: 针对采用串联谐振变换器电容器充电电源的不足，通过分析、改进并联谐振变换器拓扑，研制了基于并联谐振全桥变换器研制的10 kJ/s，100 kV电容器充电电源，变换器开关采用脉冲宽度调制技术，开关频率达40 kHz，电源的反馈控制电路基于数字信号处理全数字控制器。并给出了充电电源及主要部件高频高压变压器的设计注意事项、经验及实验结果。Abstract: A 10 kJ/s， 100 kV supply has been presented to meet high-quality power requirements in capacitor charging power supply(CCPS) applications. The power supply is designed based on a parallel resonant inverter. It may operate with pulse width modulation mode at a fixed switching frequency up to 40 kHz， and adopts digital signal processing controller to realize its feedback control. This paper also presents the design experience and experimental results of the CCPS and its main component high-frequency high-voltage transformer.
