Repetitive pulsed power generator based on inductive-energy-storage pulse forming line

利用传输线中的电感单元和电压叠加的方式来获得纳秒(ns)级矩形高压脉冲是一种全新的思路。描述了这种发生器的基本原理,并利用同轴电缆和MOSFET开关制作了两种原型脉冲发生器(单线型和双线型)来论证此方案的可行性,并进行了初步实验验证,在四模块叠加的情况下,分别实现了4kV/20 A,20ns和2kV/40A,20ns的短脉冲。实验结果表明,电感型脉冲形成线电压叠加器是一种有潜力的紧凑型高压脉冲发生器。

It is a new way to obtain nanosecond high voltage pulse by employing inductive pulse forming line and voltage adder technology.In this paper,the basic principle of the generator is described,and two kinds of prototype pulse generators(single line and double line types)are fabricated by using coaxial cable and MOSFET switch to demonstrate this idea.The preliminary experiments,in the case of four module superposition,have achieved nanosecond short pulses(4 kV/20 A,20 ns and 2 kV/20 A,20 ns,respectively).
