摘要: 提出一种由三导体同轴线构成的脉冲形成线技术方案，利用中筒改善内外筒间电场分布，提高平均场强，从而获得更高的形成线电压及储能。利用双次级Tesla变压器为形成线充电，简单分析了电路特点及次级电压波形，给出两个筒间隙电压达到恰当比例对应的充电时间。通过优化内筒、中筒半径，得到形成线电压和储能曲线，结果表明:外筒半径固定时，形成线电压和储能均存在最大值。特别分析了有效储能问题，给出了有效储能曲线和能量效率曲线。Abstract: A pulse-forming line with three conductor coaxial-line and Tesla transformer is presented. The electric field distribution between inner and outer conductors is improved and the average field intensity is increased by using the middle conductor, thus higher peak voltage and energy storage of the pulse-forming line is obtained. The pulse-forming line is charged by Tesla transformer with dual secondary windings. The characteristics of circuit and the voltage waveforms of the secondary windings are analyzed. The charge time when the voltage ratio of the two conductor gaps reaches its optimal value is also presented. The voltage and energy storage curves of the pulse-forming line are obtained through optimizing radiuses of the inner and middle conductors. The result shows that both the voltage
