摘要
介绍了逆变器谐波电流均方根值最小的脉宽调制 (PWM )。以谐波电流均方根值最小为运行性能指标 ,建立了最优开关模式。这种PWM技术可大大减少电动机的附加损耗和脉动转矩。
This paper introduces the pulse wide modulation(PWM) based on minimum root-mean-square value of harmonic current of inverter.The optimum switching partterns are developed with operation performance index of the minimun root-mean-square value of harmonic current.The PWM technique can decreases largely the supplementary loss and pulsation torque of motor.
