【摘要】 Marx发生器作为高功率微波辐射系统的驱动源,较易实现高输出峰值电压、结构紧凑、体积小,在系统小型化研究方面占据优势。介绍了紧凑型重复频率Marx发生器的结构特点,通过理论分析和实验研究,研制1台14级重复频率Marx发生器。采用正负双边恒流充电及全电感隔离,减小了能量损失,提高了Marx发生器工作重复频率。采用火花间隙开关和Marx绝缘一体设计,省略电容充电对地回路,使整个系统结构更加紧凑、简便,整个Marx发生器被放置在一个密封的金属圆筒内,圆筒内充SF6气体进行高压绝缘。通过调试,Marx发生器实现稳定、重复频率工作,充0.16MPa的SF6时,输出电压约为475kV,脉冲前沿约为20ns,可以在重复频率1～20Hz下稳定运行。更多还原

【Abstract】 Presently,the high power microwave(HPM) radiation systems are widely concerned by researchers,as a driver of HPM radiation system.Marx generator has the advantage because of its high output peak power,compact structure and small volume.This paper introduces the characteristics of a compact Marx generator with repetitive working frequency.Based on the theoretic analysis and experimental research,a 14-staged compact and repetitive Marx generator with inductive isolators is developed.It is charged synchronously with positive and negative constant current,and designed with spark switch and Marx high voltage insulation integrative,as well as omitted capacitance charging ground loop which makes the whole system concision and compact.According to debugging,its output voltage is up to 475 kV with a rise-time about 30 ns,and works stably in the repetitive frequency of 20 Hz when it fills with 0.16 MPa pure SF6.更多还原
