Design of the high repetition high voltage nanosecond pulse generator based on SOS

依据高重频高压纳秒脉冲输出的要求,基于半导体断路开关(SOS)的工作特点,设计了高重频高压纳秒脉冲源脉冲发生器线路。分析发生器线路的工作原理,对输出脉冲幅度50 k V/100Ω、脉宽约10 ns^20 ns和重复频率100 k Hz脉冲源的线路中关键器件的参数进行了计算。分析关键器件SOS、饱和脉冲变压器、副开关要求,给出了关键器件的选型参考。

A design scheme is put forward according to the characteristic of high-repetition high-voltage nanosecond output wave and the operation characteristic of Semiconductor Open Switch(SOS), which generates special pulse wave by SOS. The operation process of the circuit is analyzed. Parameters of some important components in generator which can output 50 k V/100 Ω, 10 ns-20 ns and 100 k Hz pulse wave are computed. Through analyzing the requirements on some important components including SOS, saturated transformer and subsidiary switch, an advice is presented on how to select these important components.
