ns级快脉冲电源研制

高重复频率ns级快脉冲电源是粒子加速器超快kicker注入引出技术中有待攻克的关键技术难题。本工作利用计算机仿真和桌面实验等手段从理论上研究了感应叠加技术、射频MOSFET开关及驱动电路技术，并在此基础上设计研制了1台10级感应叠加的快脉冲电源性能样机。经初步测试，10级叠加性能样机在500 Hz低频工作条件下，输出脉冲幅度>4.3 kV，脉冲前沿<2.8 ns，脉冲宽度<9 ns，基本达到了预期目标。

Research and Development of ns Pulse Width Ultrafast Pulsed Power Supply

High repetition rate, nanosecond pulse width fast pulsed power supply is a key technology to be overcome for particle accelerator fast kicker injection and ejection. In this paper, inductive adder topology, the RF MOSFET and its driver circuit were studied by computer simulation and table circuit experiment. On the basis of theory research, a ten-grade inductive adder pulsed power supply evaluating prototype was developed. The preliminary test of the prototype was completed. A ten-grade adder can produce a short pulse of pulse amplitude>4.3 kV, front edge<2.8 ns, and pulse width< 9 ns into 50 Ω at 500 Hz repetition rate.
