摘　　要：介绍了一种波形可调的高电压快前沿脉冲源。该脉冲源由Marx发生器、脉冲成型组件、主开关、匹配负载、分流电阻、串联电感等部件构成。各部件白成一体，呈模块化分布。以Marx发生器作为初级储能，通过调节发生器输出端分流电阻、串联电感及脉冲成型组件等模块，可以输出包括双指数波和方波在内的5种脉冲波形。输出脉冲幅值在200600kV范围内可调，最小脉冲前沿可达2ns。A high voltage pulse generator with fast rise-time and adjustable output waveform was developed. The new generator is mainly composed of five separate modules including Marx generator, pulse forming assembly, main switch, matching load and test cavity. The Marx is the primary energy storage of the generator. An alterable shunt resistor and a tunable inductor are placed in the output terminal of the Marx. By adjusting the assembly of shunt resistor, tunable inductor and the separate modules, multiple output waveforms （four exponential waveforms and a rectangular waveform） could be produced. The pulse width of the output waveform could be varied from 20 ns to 1 μs, and the amplitude of the output voltage could be regulated from 200 kV to 600 kV. The minimum rise-time of the output waveform of the generator is no more than 2 ns.
