摘　　要：在验证性实验结果的基础上,对超导磁储能多模块脉冲电流发生装置进行数学建模,分析了脉冲变压器对输出脉冲波形的影响,并提出了脉冲变压器参数选择的准则。对于实验中出现的储能模块间互感影响放电波形的问题,对储能模块进行电磁场有限元分析,提出了模块间隔放电的控制策略,仿真结果显示其可以有效发挥模块性能。Based on the experimental results, this paper established a mathematic model to analyze the influence of switch control strategy on the multi-module SMES pulse current generator＇s performance, including current pulse waveform and energy transmission efficiency of pulse transformer. To solve the problem caused in mutual inductance among modules, a new control strategy was proposed based on the finate element analysis of the magnetic field. With the simuation result it shows the device＇s performance is improved.
