摘　　要：基于RSD单次运行,本文研究了其重复频率运行,设计了重频运行系统,针对系统中电容充电速度较慢的问题,首次提出用四倍压电路给电容充电,以提高系统的运行频率。仿真和实验结果均显示,四倍压电路实现了电容快速充电,可在150μs内将3μF电容充电至2.0kV。基于四倍压电路充电,系统运行频率可达500Hz,放电电流达2.2k A(脉宽为9μs),di/dt为497.2A/μs,且器件工作稳定。The repetitive frequency operation of RSD was studied and the circuit was designed based on the single operation of RSD in paper. Aiming at the problem that the capacitor in system was charged with a low speed, four-multiple-voltage circuit was firstly advanced to charge capacitance, which improves the operation frequency of the pulse power system. Simulations and experiments show that the fast charge of capacitor was achieved by four-multiple-voltage circuit, and the voltage of capacitance of 3~F can reach 2.0kV within 150ps. The operation frequency of the system can reach 500Hz based on the four-multiple-voltage charge, and the peak current is 2.2kA （pulse width is about 9μs）, di/dt 497.2A/μs.
