摘　　要：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50Ω时,可同步输出两种快脉冲触发信号:一种幅度大于20V(4路)、脉冲前沿小于820ps、脉冲宽度大于100ns;另一种则是幅度大于100V(4路)、前沿小于1.4ns、脉宽大于100ns;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2ns和36.6ps。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(5kHz)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 concen tric and sameness space transfer, a modularity fast pulse trigger with many channels in phase was designed. The above pulse trig get with a load of 50% can export two fast pulse trigger signals that is one signal with more than 20 V output voltage （four chan nels）, 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 thanl00 ns pulse width, and with the exterior trigger, the jitter of the pulse trigger a chieves 2 ns and the in phase decentralization character of the pulse output achieves 36.6 ps. The experiment results of single ex terior 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.
