Multilevel inverter powered induction motor drive technology essay
A speed sensorless control strategy is investigated in a wide speed range based on an extended Kalman filter EKF and direct torque control with space vector modulation DTC-SVM for three-level cascaded H-bridge inverter-fed permanent magnet synchronous motor drives. The implementation of conventional SVM technique in the. Among these topologies, the CHB-powered induction motor drive is preferred, especially in medium-voltage MV drive applications, due to its several advantages such as simple inverter structure.
