A Novel Five-Level Power Converter With Model Predictive Torque Control for Four-Phase SRMs

This article proposes a novel five-level power converter with only 12 switches and 12 diodes for a four-phase 8/6-pole switched reluctance motor (SRM), combined with a model predictive torque control (MPTC) strategy to suppress torque ripple. To overcome the high computational burden caused by the multilevel design, a candidate voltage vectors (CVVs) selection method is designed, reducing the number of CVVs to 9 or 5 at each control period. The effectiveness of the proposed topology and control
