摘　　要：研制了一台体积小 ,重量轻的新型 ns级电压脉冲发生器 ,可用于电声脉冲法测量空间电荷的试验装置中。该发生器采用以开关电路为基础的电源代替原来的工频整流电源 ,以湿簧管代替火花间隙 ,使得电源的重量下降到原来的 1/5 ,体积也大缩小。经试验可输出脉冲宽度为 2 0 ns,幅值最高为 2 0 0 0A novel and compact high-voltage nanosecond pulser is produced, which can be used in the Pulsed Electro-acoustic(PEA) measuring apparatus. In the nanosecond pulser, the original main frequency power rectifier and wet reed relay are substituted by switching dircuit and spark gap, respectively. It is the result that the weight of power source is reduced by a factor of 5 and the capacity becomes much smaller. Itcan generate adjustable voltage pulses 20 ns in width and 2 000 V in amplitude.
