针对当前超快脉冲和超高重频脉冲产生技术需求，基于固态半导体开关技术和脉冲合成技术，提出了一种基于延时触发控制的高重频可重构脉冲产生方法，研制了kV/MHz高重频可重构脉冲源原理型装置。测试结果表明，该脉冲源能够稳定输出幅度为1 kV、重复频率1 MHz、前沿时间约700 ps的亚纳秒脉冲，通过精确调节各脉冲触发时间顺序还可灵活改变脉冲前沿、脉宽和波形等参数，并能实现1～50 MHz重复频率的参数调节，可有效满足电子对抗、超宽带探测及通信等行业领域的应用需求。

Research on kV / MHz reconfigurable pulse generation technology

In order to meet the requirement of ultra-high repetition frequency pulse generation in current ultra-fast pulse generationtechnology, this paper proposes a high repetition frequency reconfigurable pulse generation method based on solid state semiconductorswitching technology, pulse power synthesis technology and picosecond high precision delay trigger control technology, and develops aprototype device of high repetition frequency reconfigurable pulse generator with kV/ MHz. The test results show that the pulse generatorcan stably output sub-nanosecond pulses with amplitude 1 kV, repetition frequency 1 MHz, rise time 700 ps. By precisely adjusting thetrigger time sequence of each pulse, the rise time, pulse width and waveform can be flexibly changed, and the repetition frequency canbe adjusted from 1 MHz to 50 MHz. It can effectively meet the application requirements of electronic countermeasures, ultra-widebanddetection and communication industries.
