摘　　要：介绍了一种50 kV紧凑型自动化纳秒脉冲源,输出脉冲幅值1~50 kV连续可调,输出前沿约2 ns,脉宽约21 ns,搭配有界波导波天线,可建立满足IEC61000-2-9标准要求的电磁环境。该脉冲源采用电容直流充放电的方法实现输出电压连续可调,通过改变储能电容大小的方法实现输出脉冲脉宽可调。研制了一套远程光控的控制系统实现脉冲源的全自动化运行。该脉冲源可用于绝缘材料击穿特性试验,以及外接导波天线可产生特定的电磁环境等。通过设计和选用更高耐压的储能电容、充电绝缘子等部件,脉冲源可输出更高的电压。A 50 kV compact automatic nanosecond pulse source was developed.The working principle of the pulse source,its structure design and the development of automatic control system are introduced.The typical electric field waveform of a pulse source connected to a guided wave antenna is given.The output voltage of the pulse source can be adjusted continuously by DC capacitor charging method,and the output pulse width can be adjusted by changing the storage capacitance.The pulse source can be used to generate electromagnetic environment and test the breakdown characteristics of insulating materials.The output of higher voltage can be realized by selecting and designing higher voltage storage capacitors and charging insulators.
