Abstract

Abstract: A novel 12 voltage vector control strategy for switched reluctance motors (SRM) with a T-type three-level converter is proposed in this study. Based on a causal analysis of torque ripple under the control of conventional six voltage vectors, six new voltage vectors are added for further reduction of torque ripple. An optimized control rule is adopted based on the division method of the 12 new voltage vectors. A zero-voltage vector is used to adjust the duration of the 12 voltage vectors, the time of which is varied at different parts of the vector sectors according to the torque error. In addition, the windings are connected in a delta configuration, therefore, the number of connections between the converter and SRM is reduced. Finally, the results of MATLAB/Simulink and RT-LAB are presented to verify the validity of the proposed scheme.

Key words: Switched reluctance motor (SRM), T-type three-level converter, vector control
