摘　　要：利用电力电子技术与脉冲功率技术设计了一台纳秒级高压脉冲电源。电源低压部分采用电力电子技术中的BUCK电路与串联谐振电路,高压部分采用脉冲功率技术中的磁脉冲压缩(MPC)网络与半导体断路开关(SOS)。对高压脉冲电源的整体设计作了阐述,介绍了可饱和变压器与磁开关、晶闸管、半导体断路开关的参数设计。利用PSPICE软件和泰克示波器两种方式对所设计的电源进行了仿真和试验。试验测得在输出负载上产生了一个峰值高达50 k V、半高宽为120 ns的负极性脉冲。A nanosecond high pulse power based on power electronics technology and the pulsed power technology was developed. The BUCK-circuit and series resonant circuit are exerted by the low voltage part of power source,meanwhile the high voltage part mainly adopts the magnetic pulse compression network( MPC) and semiconductor opening switch( SOS). This paper introduced the overall design of the high pulse power,which involves the parameter design of the saturable transformers,the magnetic switch,the thyristor and the semiconductor opening switch. The PSPICE software and Tektronix oscilloscope were used to simulate and test on the designed power source. A negative pulse is produced whose peak value of 50 k V magnitude and the width of 120 ns are measured on the output load.
