紧凑型长脉冲功率模块研制
High Power Laser and Particle Beams（2015）
Abstract
设计了基于Blumlein脉冲成形网络(PFN)的紧凑型长脉冲功率模块.该模块将两路阻抗各为20 Ω的Blumlein脉冲形成网络对称连接于LTD的初级绕组上,并采用同一个气体开关驱动,以保证两路PFN工作同步.PFN采用直角弯折“L”型结构,这种结构既保证了PFN与开关连接紧凑,又将模块横向尺寸缩减至最短,且对输出脉冲波形影响不大.实验结果表明,研制的长脉冲功率模块在10 Ω负载上输出脉冲幅值约为135 kV,半高宽约为180 ns,前沿约为50 ns,平顶约为100 ns,重复脉冲频率可达到25 Hz.
