摘    要:基于等阻抗-双脉冲成形线技术,建立了一个超宽带高能高功率微波发生器理论模型。计算机模拟结果表明:利用等阻抗超宽带高功率微波发生器,可以同时产生纳秒主脉冲和皮秒前沿脉冲;通过控制皮秒脉冲成形线输出开关闭合的延迟时间,可以调制皮秒脉冲和纳秒脉冲的输出电压比值;通过调节纳秒脉冲成形线与皮秒脉冲成形线的电容比值,可以控制皮秒脉冲的脉宽和皮秒脉冲的峰值电压;利用等阻抗超宽带高功率微波发生器,可以最大限度地提高辐射脉冲能量和整个系统的能量转换效率。

关 键 词:超宽带高功率微波发生器    皮秒脉冲功率技术    纳秒脉冲功率技术    Marx发生器

Abstract:According to the impedance-matched pulse-forming-line technology, the theoretical model of an ultra-wideband high power microwave generator is established, and corresponding simulations are carried out. The results show that, the generator can generate a nanosecond pulse and a front picosecond pulse, with the impedance-matched technology. The switching delay of picosecond switch has an influence on the picosecond pulse voltage, and smaller capacitance of the picosecond pulse-forming-line leads to higher radiated pulse voltage and narrower picosecond pulse-width. The transfer efficiency of stored energy in pulse-forming-lines to microwave is 100% in theory.
Keywords:ultra-wideband high power microwave generator  picosecond pulsed power technology  nanosecond pulsed power technology  Marx generator
