本文介绍了一种脉冲发生器，其输出电压范围为0.1 ~ 6 kV，最大输出电流为150 A，脉冲宽度范围为100-300 ns，在50 Ω电阻负载上上升时间为10 ns，下降时间为25 ns，重复频率大于1 MHz。该电路具有在所需电压下充电的10 nF的源电容器，该电容器通过并联的两个快速高压固态开关向负载馈电。纳秒级的上升时间和脉冲的平方方式已经完成安排所有组件在圆柱对称。将两个极性相反的电路耦合，获得双极脉冲。
A pulse generator with the following characteristics is presented: the voltage ranges in the interval 0.1–6 kV, the maximum delivered current is 150 A, the pulse length ranges within the interval 100–300 ns, the rise time and the decay times are, respectively, 10 and 25 ns on 50 Ω resistive load and the repetition rate is higher than 1 MHz. The circuit has a source capacitor of 10 nF charged at the needed voltage, the capacitor feeds the load through a parallel of two fast and high voltage solid state switches. The nanosecond rise time and the square fashion of the pulse have been accomplished arranging all the components in cylindrical symmetry. A bipolar pulse is obtained coupling two circuits with opposite polarity.
