本文提出了一种新颖的系统，用于对感应电机（IM）无位置传感器驱动系统的无电解电容器逆变器源电流进行谐波抑制控制。所提出的系统基于初级磁链的估计。本研究将IM控制系统的应用范围扩展到三相到三相电解电容逆变器。此外，采用直接直流母线电流控制来改善源电流波形。通过实验结果验证了控制系统的有效性。
This paper proposes a novel system for harmonics reduction control of the source current of electrolytic capacitorless inverters for a position-sensorless drive system of an induction motor (IM). The proposed system is based on the estimation of the primary flux linkage. In this study, the application range of the control system of the IM is extended to a three-phase-to-three-phase electrolytic capacitorless inverter. Moreover, a direct dc-link current control is employed to improve the source current waveform. The validity of the control system is confirmed through experimental results.
