| 摘 要： | 雪崩效应因为能在极短时间内输出极大电流,常被用来设计高压脉冲电路。分析了利用雪崩三极管电路生成高压正脉冲的实现方案,并提出了改进的设计,接着分析了脉冲输出过程中负载回路的电流流向,通过改变信号输出点,设计了输出高压负脉冲的电路。电路输出的脉冲幅度达到了-200V,前沿约3.2ns。与相似结构的正脉冲电路相比,性能略有降低。同时对性能下降的原因进行了分析。

| Abstract: | Avalanche effect is usually used to design the circuit to generate high-voltage pulse due to its ability to output very large current within very short period.We analyzed the realization by using avalanche transistor to generate positive high-voltage pulse and improved it. Then by modifying the output port of load we designed a structure to output negative pulse with same amplitude.The amplitude of negative high-voltage pulse is 200V and edge is 3.2ns.Compared with the performance of the circuit which has s... |
