摘　　要：针对重复频率Marx型脉冲功率源的应用需求,采用固态调制恒流充电与脉冲变压器感应叠加相结合的技术方式,开展了大功率重复频率高电压脉冲充电电源技术研究。分析了基于BUCK-BOOST拓扑电路的恒流充电技术,给出了高电压脉冲变压器、脉冲调制模块、BUCK-BOOST充电模块、控制单元等关键参数设计,完成了大功率重复频率脉冲充电电源样机研制。样机设计指标最大输出平均功率250kW,最高重复频率100Hz。在0.5μF负载电容上进行了充电测试,获得了电压约100kV、脉冲前沿约300μs的脉冲输出。该脉冲充电电源在脉冲变压器初级设计中采用了多模块并联的设计思路,即减小了装置体积又降低了高电压绝缘风险,在输出功率大、电压高的条件下,实现了紧凑化、模块化设计。In view of the application requirements of the repetitive Marx-type pulse power source,a technology combining solid-state modulator and pulse transformer inductive adder was adopted to conduct research on high-power repetition-rate and high-voltage pulse charging power supply technology.The constant current charging technology based on BUCK-BOOST topology circuit was analyzed,and designs of key components such as high-voltage pulse transformer,pulse modulation module,BUCK-BOOST charging module,and control unit were provided.Finally a high-power repetitive pulse charging power supply prototype was developed.The prototype design specifications include a maximum output average power of 250 kW and a maximum repetition rate of 100 Hz.Charging tests were conducted on a 0.5μF capacitive load,and an output pulse with a voltage of about 100 kV and a pulse rise time of about 300μs was obtained.The pulse charging power supply adopts the design concept of multi module parallel connection in the primary design of the pulse transformer,which reduces the device volume and high voltage insulation risk.Under the conditions of high output power and high voltage,it achieves compact and modular design.
