摘要：针对高压直流电源存在的问题，研制了一种基于谐振软开关高频逆变的大功率高压直流电源。从主电路结构、硬件电路设计和逆变控制策略等3方面给出了电源的设计过程，并对逆变主电路谐振式的工作过程予以分析说明。最后，给出了实验结果和波形，并进行了相应的分析。实验结果表明，研制出的高压直流电源能达到20 kW，30 kV的输出。

Abstract: Aiming at the problems of the high voltage direct current, a high power high voltage DC power supply based on high frequency resonant soft-switching inverter was designed. The power design process of power stage，hardware circuits and inverter control strategy were provided. And the resonant operation process of inverter circuit was also explained. Experimental results and waveforms were proposed and analyzed in the end. The results show that the power output is 20 kW,and the voltage output is 30 kV.
Key words: high voltage direct current(HVDC); high frequency; series-parallel resonant; soft-switching; planar busbar
