摘要
采用Marx发生器作为脉冲功率源,用螺旋天线作为辐射系统,设计了一种紧凑型宽实验结果为:辐射场中心频率为171 MHz,2 m处最大辐射场为10.5 kV/m。谱辐射源,用于宽带天线技术研究。充电系统采用24 V锂电池逆变倍压产生几十kV的交流高压,给脉冲功率系统供电。10级Marx发生器设计为同轴结构,最大输出电压200 kV,整个Marx发生器尺寸为ф150 mm×550 mm。Marx发生器产生的脉冲经过辐射系统,最后通过螺旋天线辐射出去。
A compact wide-band source based on Marx generator is designed, which is powered by a pair of 24 V,15AH（Ampere-Hour） lead acid batteries, inverted and multiplied to generate high-voltage alternating current（lOs of kV）. Marx generator is a compact ten-stage coaxial high voltage pulse generator with a total size of φ 150 mm ×550 mm. With a maximum of 20 kV charge voltage, this generator has an open circuit voltage of 200 kV. The fast voltage pulse generated by Marx source is applied directly to drive a spiral antenna. The experimental results show that the peak E field is 10.5 kV at a distance of 2 m from the radiation antenna, with a center frequency of 171 MHz.
