单相逆变电源输出侧RC补偿支路的设计

摘要

针对先进实验超导托卡马克(EAST)核聚变装置上的共振磁扰动(RMP)线圈电源,根据输出电压纹波等设计指标,发现其输出侧仅有LC滤波器时,系统会不稳定,通过理论分析结合电路仿真,在输出侧并联一个RC补偿支路,比较不同的RC参数组合,发现在RC补偿支路参数合适时,能极大地提高系统稳定性,实验结果表明电源此时能达到各项设计指标,同时保持稳定运行.%For the resonant magnetic perturbation (RMP) coil power supply on the experimental advanced superconducting Tokamak (EAST) device,according to the design requirement of output voltage tipple,the system will be unstable when the output side only has LC filter.By theoretical analysis and simulation,the RC compensation branch with proper parameters can improve the stability of the system.And the experimental results show that the power supply can satisfy several design parameters and run steadily.
