直线变压器驱动源多路开关同步触发技术

近年来，随着快脉冲直线变压器驱动源（LTD）技术的快速发展，装置中气体开关数目成倍增长，多路开关同步触发技术已经成为制约LTD技术发展的瓶颈之一。分别从电脉冲触发、激光触发及基于光导开关（PCSS）的同步触发3个方面，概述了近年来国际上LTD的发展现状,以及各国为实现多路开关同步触发所做的研究工作，阐述了每种触发方案的优缺点，对多级多通道开关的结构及触发特点与要求进行了调查。结合LTD装置同步触发的现状，对未来相关关键技术进行了探讨和展望。

Multi-output synchronization trigger for linear transformer driver

With the development of linear transformer driver, the number of gas switches in the driver increases rapidly, and thus multi-output synchronization trigger has become one of the key technical obstacles. The paper summarizes the recent researches about electrical pulse trigger, laser trigger and trigger based on photo-conductive semiconductor switches. Characteristics and trigger requirements of multi-channel multi-gas switches are reported. Developments in key technologies of trigger system are analyzed. The crucial technique problems that should be investigated in the future and some research approaches are presented.
