Different voltage limiting methods of pulse power supply based on superconducting pulse transformer

  • 摘要: 电感储能是脉冲功率技术的主要储能方式之一,而断路开关的限压问题是其固有难题。为了探究超导脉冲电源的限压方法,介绍了ZnO压敏电阻限压和脉冲电容器限压两种传统限压方式,提出联合脉冲电容器和压敏电阻以限制断路开关电压。分析了三种限压方式下超导脉冲电源的工作原理,基于同一超导脉冲变压器参数进行仿真,并分别分析了不同限压参数下的输出特性,对比分析了不同限压方法之间的输出特性差异。针对联合限压方式,为验证其限压性能,搭建了小型实验平台进行验证性实验。仿真和实验结果表明,联合限压方式比压敏电阻限压传输效率高,关断性能好;比脉冲电容限压放电速度快,电压幅值低。
