英文摘要：

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.
