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。Inductive energy storage is one of the main energy storage methods of pulse power technology,and the problem of limiting voltage of open circuit switch is its inherent problem.To explore the voltage limiting method of superconducting pulse power supply,this paper introduces two traditional voltage limiting methods,namely ZnO varistor voltage limiting and pulse capacitor voltage limiting,and puts forward the combination of pulse capacitor and varistor to limit the open switching voltage.The working principle of superconducting pulse power supply under three voltage limiting modes is analyzed,and the output characteristics under different voltage limiting parameters are simulated based on the same superconducting pulse transformer parameters.Aiming at the combined voltage limiting mode,a small experimental platform was built to verify the voltage limiting performance of the device.Simulation and experimental results show that the combined voltage limiting mode has higher transmission efficiency and better turn-off performance than varistor,and it has faster discharge and lower voltage amplitude than pulse capacitance limiting mode.
