摘要

脉冲变压器与陡化开关结合的方式是产生纳秒脉冲较为成熟的方式, 采用这种方式, 研制了一种基于空芯Tesla变压器和陡化开关的紧凑高压重复频率纳秒脉冲源。该脉冲源主要由重复频率充电模块、Tesla变压器和陡化开关三部分组成, 重复频率充电模块主要通过晶闸管的时序配合实现, Tesla变压器为脉冲源装置系统的核心及主升压模块, 陡化开关是一个三电极自击穿型气体开关, 用于将变压器次级输出的电压陡化成纳秒快脉冲波形, 对该重复频率脉冲源以上各部分进行了详细的设计和测试。实验结果表明, 该脉冲源可以在6 kΩ的负载电阻上输出幅值100 kV、上升沿约为30 ns、最高频率可达500 Hz的高压纳秒脉冲。

Abstract

The combination of pulse transformer and sharpening switch is a relatively mature way to generate nanosecond pulse. In this way, a compact high voltage repetitive nanosecond pulse generator (HRNPG) based on Tesla transformer and spark switch is developed in this paper. The pulse generator mainly consists of a repetitive charging module, a Tesla transformer and a sharpening switch. Repetitive charging module is mainly implemented by temporal coordination of two thyristors, Tesla transformer is the core of the pulse generator and main booster module, sharpening switch is a three electrode self-breakdown type gas switch, which is used to sharpen the transformer secondary voltage into nanosecond pulse waveform. Each part of the HRNPG is presented and tested in detail. Applied to a 6 kΩ resistor, the HRNPG prototype is capable of generating a pulse with 100 kV peak voltage and 30 ns rise time at the maximum repetition rate of 500 Hz.
