在没有电感或电解电容器的单相转三相逆变器中，由于没有功率因数校正电路或能量缓冲器，逆变器不仅要控制电机，还要控制输入功率因数。为了提高输入功率因数，提出了几种控制方法。然而，如果电机存在由转子结构引起的较大空间谐波，控制系统的带宽限制将对电源电流响应产生不利影响，从而导致电源电流谐波。本文提出了一种谐波电流抑制控制器，使得获得正弦电源电流成为可能。该控制器关注电源电流与直流环节平均电流之间的关系，并采用前馈控制方法对电源电流进行控制。实验验证了该方法的有效性。
In a single-phase to three-phase inverter that does not have an inductor or electrolytic capacitor, the inverter must control not only the motor but also the input power factor because there is no power factor correction circuit or energy buffer. To improve the input power factor, several control methods are proposed. However, if the motor has large spatial harmonics caused by the rotor structure, the bandwidth limitations of the control system adversely affect the source current response and thereby cause source current harmonics. This paper proposes a harmonic current reduction controller that makes it possible to obtain a sinusoidal source current. The proposed controller focuses on the relationship between the source current and the average DC-link current and controls the source current using a feedforward control method. The effectiveness of the proposed method is experimentally verified.
