摘要 针对超导电力系统中超导电缆和超导储能线圈测试需要模拟短路冲击大电流的试验需求,提出了基于脉冲电容器的高压振荡发生器设计方案并对电路进行了理论分析和电路仿真,着重分析了回路电阻对振荡电流持续时间的影响。仿真结果与理论分析结果相吻合,该结果表明:所设计的高压振荡发生器可以实现25 k A的峰值电流输出,衰减时间可达1 s,能够满足当前超导电力电缆或超导储能线圈冲击大电流试验的需要。 For high-current pulse experiment of superconductor cables or coils,a pulse power supply based on capacitors is proposed. Detailed analysis and simulation of the power scheme are carried out,and the influence of circuit resistance to the oscillation current duration is analyzed on emphasis. The results show that the power supply can obtain an output current of 25 k A with decay time larger than 1 s. This scheme could meet the requirement of high-current pulse experiment of superconductors.
