【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。
[Abstract]:According to the resonant magnetic disturbance (RMP) coil power of the advanced experimental superconducting Tokamak (EAST) nuclear fusion device, according to the design index of output voltage ripple, it is found that the system will be unstable when the output side is only LC filter. Through theoretical analysis and circuit simulation, a RC compensation branch is parallel in the output side, and the different combination of RC parameters is compared. It is found that the stability of the system can be greatly improved when the parameters of the RC compensation branch are suitable. The experimental results show that the power supply can reach all design indexes at this time and keep stable operation at the same time.
