Five-Level Inverter-Fed Model Predictive Current Control for a Five-Phase PMSM Drive.

In this paper, a five-level inverter-fed Model Predictive Current Control (MPCC) of Five-Phase Permanent Magnet Synchronous Motor (PMSM) Drive is proposed to enhance the performance of the drive by reducing the torque ripples. The MPCC method provides a good steady-state performance and also this method does not require a weighting factor. Among the various torque ripple minimization techniques, the multilevel inverters attracted more attention in electric drives due to rapid development in semiconductor technology. The performance analysis of a five-level (5L) inverter-fed five-phase PMSM drive is compared with two-level (2L) and three-level (3L) inverter drives under various operational conditions. The effectiveness of the proposed method is analyzed using MATLAB/SIMULINK software and also implemented using a real-time simulator. [ABSTRACT FROM AUTHOR]
