摘要
传统的正交铁心可控电抗器通过控制在正交铁心上的直流偏磁磁场间接控制交流磁场,铁心工作在饱和区,因此其工作电流中含有谐波。该文提出一种基于EU正交铁心的单相和三相正交可控电抗器。由于特殊的磁路结构,单相EU正交铁心可控电抗器输出电流中的谐波得到了降低,三相EU可控电抗器的输出电流中3次谐波成分很低。使用三维非线性磁阻模型建立了EU正交铁心的仿真模型进行仿真研究,并分别制作了单相和三相EU正交铁心可控电抗器样机进行实验。仿真分析和实验结果均验证了新型EU正交铁心可控电抗器的谐波含量较传统正交铁心可控电抗器低的特点。
Conventional ferrite orthogonal core （FOC） variable inductor worked in saturation state formed by a DC current control, so increases the harmonics in the AC current. T A single-phase variable inductor and a three-phase variable inductor are presented based on EU ferrite orthogonal core. The single-phase EU core variable inductor reduces harmonic component of its output current resulted from unique structure. The three-phase EU core variable inductor contains seldom third harmonic component in output current. Simulated module is setup employed 3D nonlinear reluctance method, and the single phase and three phase EU core variable inductor prototype are made respectively. Their basic characteristics are also verified by simulation and experiment result respectively.
