Abstract

Employing Modular Multilevel Converters (MMC) has recently gained notable attention in the application of three-phase motor drives. In this paper, a deadbeat-Assisted scheme has been proposed for making possible the implementation of the well-known Predictive Torque Control (PTC) strategy, for an induction motor connected to a three-phase MMC. Despite several advantages of the PTC scheme, it hasn't been widely used for multilevel topologies; due to the huge number of switching states of these converters. Employing the technique suggested in this work would result in significantly reduction of the computational load, by calculating an initial reference voltage vector based on the deadbeat approach; in order to control the stator flux and torque of the motor. Next, the predictive scheme evaluation process is conducted once more to simultaneously control the stator flux, torque and circulating current. Finally, the switching states are chosen in a way that the voltage of the cells' capacitors are kept balanced. The proposed scheme could also provide the capability of adding the voltage ripple reduction control techniques at low speeds. The performance of the proposed scheme is validated through simulations in the MATLAB/Simulink software.
