| 摘 要： | 研究了变频器输出谐波电源对永磁直线同步电动机的磁势、电流、损耗、效率等的影响,分别计算了同台永磁直线同步电动机在传统正弦波电源与变频器输出非正弦电源下的效率、功率,分析了谐波问题的影响。给出了补偿变频器输出谐波的方案,采用基于瞬时无功功率理论的ip-iq的谐波电流检测法对谐波进行检测,仿真结果为提高变频器供电电机的绝缘及永磁直线同步电动机的推广应用提供了依据。

| Abstract: | Harmonic characteristics,such as magnetic potential harmonic current losses,and efficiency,of the permanent magnet linear synchronous motor(PMLSM) fed by pulse width modulation(PWM) voltage source inverter were discussed and calculated.Program was given to compensate inverter output harmonic.Based on instantaneous reactive power theory ip-iq harmonic current detection method,the results provide a basis for the insulation of the motor supplied by inverter and the application and popularity of PMLSM. |
