用磁开关取代传统冲击电压发生器的放电球隙,利用磁开关可高重复频率工作和磁压缩陡化的特点和冲击电压发生器“并联充电,串联放电”的特点,可形成重复频率快前沿高压脉冲。建造了基于磁开关的冲击电压发生器,试验表明:其重复频率可达1 kHz,在1 nF的电容负载上可形成17 kV,上升时间小于80 ns的高压脉冲。

The novel repetitive frequency impulse voltage generator utilizes both the feature “high repetitive rate and magnetic compression” of magnetic switch and the feature “charging in parallel and discharging in series” of Marx generator. It is possible to generate high voltage impulses with rapid rise time and high repetition rate by replacing the spark gaps in the traditional impulse voltage generator with magnetic switches. A magnetic switch based impulse voltage generator was built and the output impulses with a magnitude of 17 kV,a rise time of 80 ns and a repetition rate of 1 kHz were achieved on a 1 nF capacitive load.
