摘要
为解决Tesla-PFN型长脉冲功率源在高电压下多个加载线串联时加载线之间出现的电磁干扰问题,对一种环形串联加载线的结构进行了优化设计,重点解决了加载线与形成线的阻抗匹配及加载线的高压绝缘问题。优化了过渡段结构,使形成线与加载线阻抗匹配较好,输出脉冲顶部平坦;利用静电场分析软件计算了加载线的电场分布,通过调整屏蔽环的形状和位置使电场分布更加均匀。
Abstract
In order to solve the electromagnetic interference among multi-loaded lines in series when the Tesla-PFN(pulse forming network) long pulse power generator operates under high voltage, the structure of the annular loaded lines in series is optimized and designed, with emphases on the impedance matching between loaded lines and pulse forming line(PFL) and the high voltage insulation of loaded lines. The structure of transition part is optimized, which realizes good impedance matching between loaded lines and PFL and makes the top of the output pulse flat. The electric field distribution of the PFNs is calculated by using a static electric field analysis software, and the distribution is evened by adjusting the shape and location of shielding loop.
