| 摘 要： | 为实现脉冲功率源小型化，设计了一种螺旋形薄膜介质Blumlein线，应用火花隙开关对其进行了放电实验研究，并对负载电压波形进行了分析。结果表明，开关电感会减缓脉冲前沿，电极直流阻抗使得负载输出电压效率显著降低，波形平顶趋于减小，分布电容耦合造成负载电压的预脉冲，而均压层不会影响传输特性，不会对负载电压波形造成影响。

| Abstract: | A spiral parallel-plates Blumlein line with polypropylene dielectric and film aluminum electrodes was designed. With the gap switches connected, its discharging characteristics were studied. Simulation and experimental results show that the increase in switch inductance slows down the rising of pulses and introduces reflections. The energy loss caused by film electrode resistance lowers the pulse top. The existence of distributed capacitance coupling leads to pre-pulsing in output waveform voltage while the voltage-sharing electrodes have no effects on discharging characteristics. |
