摘要: 提出了双路输出的螺旋脉冲形成线(PFL)结构，该结构内置用于充电的高耦合变压器，在螺旋PFL的两端各自输出一个脉冲，副路匹配输出时主路输出脉冲波形具有良好的平顶品质，主路输出脉冲能量占储能的大部分，解决了Korovin提出的螺旋PFL充电问题。对比分析双路输出的螺旋 PFL与SINUS-700/130两种技术路线，结果发现双路输出的螺旋 PFL改善了输出脉冲的平顶质量，输出功率提高29%，但是副路输出占用11%的储能，不易充分利用。Abstract: One double-channel output structure of spiral PFL(pulse forming line) with an outer shield and an inner cylinder is presented. This kind of spiral PFL comprises a high-coupling Tesla transformer with built-in ferromagnetic material as the inner and the outer cylinders. When the secondary channel outputs pulses in a matched way, the flat-topped fluctuation of the main pulse will be removed, and most of the stored energy will be delivered to the main load. The problem of the spiral line put forward by Korovin can thus be resolved. The comparison of two technical methods, the double-channel spiral-PFL one and the one applied in SINUS-700/130, shows that the flatness of the output pulse for the former is better and the output power increases by 29%, whereas the secondary load will consume 11%
