【摘要】：研制一套具有快边沿纳秒脉冲等离子体射流装置。该装置由基于Marx电路的并带有尾切开关的全固态纳秒脉冲发生器和具有针环电极结构的等离子体射流装置组成。其中,纳秒脉冲源主要由直流电源、控制电路和主电路组成,主电路为10级模块化设计的Marx电路,使用MOSFET作为主开关和尾切开关;控制电路产生同步触发脉冲信号,通过光纤进行隔离后同步驱动MOSFET工作。输出纳秒脉冲电压参数为:幅值0~8k V可调,脉宽100~1 000ns,重复频率1Hz~1k Hz,上升沿30ns左右,下降沿50ns以内。等离子体射流装置使用氩气作为工作气体,其结构为针-环电极结构。搭建等离子体射流实验平台,并能够产生稳定的等离子体,为进一步探索大气压等离子射流的应用奠定了基础。
[Abstract]:A set of nanosecond pulsed plasma jet device with fast edge is developed. The device is composed of an all-solid-state nanosecond pulse generator with tail cut off based on Marx circuit and a plasma jet with needle ring electrode structure. Set up. The nanosecond pulse source is mainly composed of DC power supply, control circuit and main circuit. The main circuit is a Marx circuit designed by 10 levels of modularization. MOSFET is used as the main switch and the tail is cut off. The control circuit generates synchronous trigger pulse signal and synchronously drives MOSFET through optical fiber after isolation. The output nanosecond pulse voltage parameter is: the amplitude is 0 ~ 8kV. The pulse width is 100 ~ 1 000 ns, the repetition rate is 1 Hz ~ 1 kHz, the rising edge is about 30 ns and the descending edge is less than 50 ns. Argon is used as the working gas in the plasma jet device. The structure of the plasma jet is a needle-ring electrode structure, and the experimental platform of plasma jet is built, and the stable plasma can be produced, which lays a foundation for the further exploration of the application of atmospheric pressure plasma jet.
