摘　　要：采用串联单传输线、并联Blumlein脉冲形成线和高重复频率固体开关等技术路线开展了MHz重复频率脉冲功率技术研究。利用串联单传输线获得了幅度约200 kV,时间间隔约500 ns的双脉冲。利用并联使用的Blumlein系统和特殊设计的汇流/隔离网络获得了幅度约275 kV,时间间隔约500 ns的三脉冲。利用并联MOSFET和感应叠加原理研制了6 kV/2.5 MHz固体调制器。结果表明:3种方式均可以猝发MHz的方式输出高品质的高压脉冲串,可根据实际的需求选择合适技术路线。Three technical appoaches were presented for the MHz repetition rate burst high-voltage generator.The solid-state driver is based on the idea of using field effect transistor（FET） array and inductive adder to switch energy from a pre-charged capacitor bank to a load.In this way,output voltage with an amplitude of 6.2 kV,a repetition rate of 2.5 MHz was achieved.Pulse forming lines（PFLs）,which are connected in series by large diaphragm switches,can produce multiple pulses.The as-developed system produced two 200 kV pulses separated by 500 ns.Especially designed blocking networks consisting of power diodes can combine several isolated pulses into a bunch.And three 275 kV pulses separated by 500 ns were achieved.
