摘　　要：常压下采用脉冲激励产生等离子体。方波脉冲电源可调节电压幅值、重复频率及脉冲宽度。重频高压窄脉冲调制器其输出波形和电压幅值受脉冲变压器漏磁电感和分布电容、等待充电回路、直流高压电源脉冲电容等参数的影响,采用电路仿真软件对其进行仿真计算,得到最高输出电压80 kV^90 kV,脉宽230 ns,脉冲前沿124 ns,脉冲重复频率可实现单次和130 Hz^1 kHz连续可调,重复频率脉冲幅值抖动在5%~10%。It is important to study the production of atmospheric gas discharge plasma with square pulsed voltage.In atmospheric air,higher voltage amplitude,convenient adjusting on voltage amplitude,frequency and width of the pulse are required.Repetitive high voltage narrow pulse modulator is a general source for the research.The wave shape and voltage amplitude of the output are influenced by the leakage magnetic inductance and distributing capacitance of the pulse transformer,charging circuit and the capacitance of DC high voltage source.Simulation analysis are performed for these parameters with Pspice software.Through tests and measurement on the repetitive high voltage narrow pulse modulator,the maximum output voltage of 80 kV,the pulse width of 230 ns,and a rise time of 124 ns,are obtained.The frequency can be adjusted from 130 Hz to 1 kHz continuously.The amplitude of the repetitive voltage fluctuates at the rate of 5%–10%.
