摘　　要：为满足高功率脉冲源小型化和高重复频率运行的研制需要,提出了一种基于固体开关(可控硅)的电感隔离型高压脉冲发生器触发控制设计方案。这种方案采用光纤收发器件及其驱动电路和高耐压脉冲变压器,研究了固体开关脉冲功率源控制技术中的触发信号高压隔离、光分多路及脉冲变压器分立或并联使用等关键技术。给出了单模块触发控制电路的设计及测试结果:5级LC回路在每级充电电压4 kV输入时,实现最终32 kV的输出,功率源模块输出/输入电压转换效率达到80%。同时对其应用特点进行了分析和讨论。To develop a high power pulsed source with high-repetition-rate operation and compact size, a trigger control sys- tem design of high voltage generator with inductive isolators is presented. The key techniques to build a control system of pulsed power source using solid-state switches（silicon controlled rectifier） are studied with optic components, driving circuit, and pulse transformer with high dielectric strength as high voltage isolator and optical data link. These techniques are trigger signal high voltage isolation, optical splitter, and pulse transformer parallel link or series link. Design and test results of the control system on single module are presented. Experiments show 32 kV output voltage with 4 kV input charge voltage of 5 stages LC generator, the generator＇s conversion of voltage between output and input is about 80%. Characteristics of application are also analysed and discussed.
