| 摘 要： | 分析了矢量控制调速永磁同步电动机中变频器产生高频谐波电流的原因,推导了d-q旋转坐标系下主要高频谐波电流的表达式,并通过有限元仿真验证了分析的正确性,该推论结果可间接应用于永磁同步电动机控制系统的高频谐波电流分析。根据推导分析结果,对永磁同步电动机高频谐波电流的转速特性、负载特性分别进行了分析,并进一步进行了仿真验证。

| Abstract: | Factors that caused the inverter to produce high frequency harmonic current were firstly analyzed and the main equations under d-q coodinate were deduced.Then the correctness of the analysis was verified with finite element method,and the deduction can be indirectly used to the harmonic current analysis in PMSM control system.Finally with the results,analysis on the speed and load characteristics were carried out respectively and further verification was performed. |
