潜水泵电流源逆变器驱动永磁同步电机的先进启动与无传感器磁场定向控制平滑切换

This article introduces a reliable startup method with a smooth transition to sensorless field-oriented control (FOC) in current source inverter (CSI) fed permanent magnet synchronous motor drives used in submersible pump applications. The strategy ensures a smooth transition to sensorless control, enhancing efficiency, and improves the reliability of the drive system. The proposed method minimize...
