【摘要】 开展了基于Marx发生器的重频脉冲功率源技术研究。该脉冲功率源主要由Marx发生器和重频充电控制系统组成。其中,Marx发生器采用20台60 nF脉冲电容器组成20级Marx,每级额定工作电压100 kV。重频充电控制系统包括高功率重频充电模块和触发控制模块。重频充电模块采用十路逆变、升压、整流串联输出的技术路线,实现了从直流30 V～100 kV的高压转换和对Marx发生器储能单元的快速充电;触发控制模块实现了对Marx触发开关的重频触发、重频充电模块与Marx发生器之间准确时序控制。该脉冲功率源单次工作时,当储能单元充电至96 kV,在约15Ω负载上已获得大于740 kV的高压输出,脉宽大于150 ns、前沿约60 ns;重频5 Hz工作时,由于重频充电模块功率还有待进一步提高,在约15Ω负载上已获得大于500 kV的脉冲串输出。更多还原

【Abstract】 A repetitive pulsed power source based on Marx is investigated.It consists of a Marx and a repetitive charging-controlling system.The 20-stage Marx generator contains 20 60 nF/100 kV capacitors.The repetitive charging-controlling system consists of a high power repetitive charging module and a trigger controlling module.By utilizing 10 inverter boost-doubling rectifier circuits to operate in parallel,a high power repetitive charging module has been designed and tested which can transform 30 V DC.to 100 kV DC and charge the energy storage unit rapidly.The trigger controlling module contains trigger unit and timing control unit.When charged to 96 kV,the pulsed power source can output single shot pulse of more than 730 kV with more than 150 ns duration time and about 60 ns rising time on a 15 Ω load.Because of power shortage of the repetitive charging module,the energy storage unit of the Marx can only be charged to about 70 kV.We have abtained5 Hz pulse train of more than 500 kV on the load.更多还原
