为满足脉冲功率实验中对多路高电压纳秒矩形波激励的需求，研制了一台21路高电压纳秒矩形波发生器。此发生器由一个单路高电压纳秒矩形波脉冲发生器和一个21路分路器组成。其中单路高电压纳秒矩形波脉冲发生器可输出幅值约1.07 kV、半高宽约10 ns、上升沿约1.45 ns的矩形波脉冲。利用21路分路器可将该矩形波脉冲分为21路矩形波脉冲，测得每路脉冲幅值可达51 V，半高宽约为10 ns，上升沿约为2.25 ns。

A 21-way high-voltage nanosecond rectangle wave pulsed power generator was developed for pulsed power experiments that require multi-way high-voltage nanosecond rectangle wave as excitation. This generator was composed of a 1-way high-voltage nanosecond rectangle wave pulsed power generator and a 1-way to 21-way convertor. The output voltage wave of the 1-way high-voltage nanosecond rectangle wave pulsed power generator was a rectangle wave whose amplitude was about 1070 V, full width at half maximum about 10.10 ns and rise time about 1.45 ns. This rectangle wave could be converted to 21-way rectangle wave using the 21-way convertor. Each way output rectangle wave of the 21-way convertor had an amplitude of 50.98 V, a full width at half maximum of about 10.15 ns and a rise time of about 2.25 ns.
