An Optimized Alternative Fixed Switching 12-Sector Space Vector Pulse Width Modulation Control of Open-End Winding PMSM Drive

Over the past few years, there has been an increase in use of open-end winding (OEW) PMSM applications. The fault tolerance topology makes OEW suitable for various intermittent operations. However, a dual inverter operation causes drive schemes to exhibit high commutation and ripple. This paper presents optimized alternative fixed switching 12-sector space vector pulse width modulation (svpwm) control drives. work reduces number without compromising system performance. In comparison with conventional 6-sector svpwm, this scheme offers three advantages. It incorporates optimal signal generation, virtual state method segmenting sectors into small sectors, methods based on sub-hexagons. Inverters are assigned voltage states sub-hexagon numbers. proposed was validated Matlab2021b Simulink environment. Based simulation results, it is found that effective PMSM. Finally, OPAL-RT (OP4500) used verify effectiveness. verification indicates its Results obtained from real-time hardware have ripple 1.25% 5% speed torque performance, respectively.
