摘要： 针对电感隔离型重频Marx发生器的充电需求，研制了一台猝发重频高压大功率脉冲充电电源。该电源采用直流电源+储能电容+晶闸管开关+脉冲变压器的技术路线，设计指标为充电电压为90 kV，充电电流1 kA，充电重复频率1 Hz～100 Hz可调，猝发工作时最大充电次数为5次。首先介绍了充电电源的工作原理，进行了电路参数计算和结构设计，得到了晶闸管、初级电源和脉冲变压器等主要器件的参数。然后试制组装了一套电源，并进行了实验验证：对等效总电容量为0.7 μF的紧凑型Marx发生器充电时，充电电压90 kV，充电时间小于120 μs，充电重复频率10 Hz。该电源的研制成功对高功率重复频率脉冲功率源的进一步小型化具有重要意义。

Abstract： In order to meet the charging requirements of the repetitive pulse power source based on inductance isolated Marx generator, a burst repetitive high-voltage and high-power pulse charging power supply was designed and developed. The power supply adopts the pulse transformer technology route, with a designed charging voltage of 90 kV, charging current of 1 kA, adjustable charging repetition frequency of 1~100 Hz, and a maximum burst charging frequency of 5 times. This article introduces the working principle of charging power supply, conducts circuit parameter calculation and structural design, and obtains the parameters of main components such as thyristors, primary power supply, and pulse transformers. This power supply charges a compact Marx generator with an equivalent total capacitance of 0.7 μF, achieving a charging voltage of 90 kV, a charging time of less than 120 μs， and technical specifications for charging repetition frequency of 10 Hz. The development of this power supply has reference significance for further miniaturization research of high-power repetitive pulse power sources.
