基于超快速高压大功率半导体开关、脉冲形成电路以及同心等间距传输的关键技术,提出一种模块化多路同步快脉冲触发源技术方案.设计出在负载阻抗为50 Ω时,可同步输出两种快脉冲触发信号:一种幅度大于20 V(4路)、脉冲前沿小于820 ps、脉冲宽度大于100 ns;另一种则是幅度大于100 V(4路)、前沿小于1.4 ns、脉宽大于100 ns;在外触发作用下,触发源系统抖动和脉冲输出同步分散性分别达到2 ns 和36.6 ps.电路结构上充分利用等间距电信号传输的原理,实现了快脉冲触发源模块化的设计.通过实验结果验证了所采用的设计原理及方法的可行性,给出了在外触发脉冲单次和重频(5 kHz)作用下该同步快脉冲触发源输出的实验结果.

Based on the fast semiconductor switch with high voltage and high power,PFN and the technology of the concentric and sameness space transfer,a modularity fast pulse trigger with many channels in-phase was designed.The above pulse trigger with a load of 50 Ω can export two fast pulse trigger signals that is one signal with more than 20 V output voltage(four channels),less than 820 ps fall time,more than100 ns pulse width and another signal with more than 100 V output voltage(four channels),less than 1.4 ns fall time,more than100 ns pulse width,and with the exterior trigger,the jitter of the pulse trigger achieves 2 ns and the in-phase decentralization character of the pulse output achieves 36.6 ps.The experiment results of single exterior trigger and exterior trigger with 5 kHz repetitive frequency for the above modularity fast pulse trigger were given,and the experiment result validates the theory and method of the concentric and sameness space transfer.
