| 摘 要： | 为抑制单边可控下的共直流母线型开绕组永磁同步电机存在零序电流的问题，本文提出了基于开关表的直接功率控制抑制零序电流的控制方法。通过建立开绕组永磁同步电机的数学模型，分析了单边可控下的共直流母线型开绕组永磁同步电机的电压矢量分配和定子磁链所在扇区。根据直接功率开关表选择合适的电压矢量，实现对系统零序电压抑制的目的。最后，通过仿真分析验证所提出的基于直接功率控制的单边可控下共直流母线型开绕组永磁同步电机零序电流抑制的可行性和正确性。

| Abstract: | In order to suppress the problem of zero sequence current in a single side controlled open winding permanent magnet synchronousmotor(OW-PMSM)with common DC bus.This paper proposed a control method for suppressing zero-sequence current based on direct power control of a switch meter.Based on the mathematical model of OW-PMSM,the distribution of voltage vector and the sector of stator flux linkage were analyzed.According to the direct power switch meter select the appropriate voltage vector to achieve the purpose of zero sequence voltage suppression system.At last,the feasibility and correctness of the proposed zero sequence current suppression method based on the direct power control and single side control were verified by simulation analysis. |
