Mitigation of DC-Link Current Ripple for Dual Three-Phase Flux-Adjustable Hybrid PMAC Drives Using Collaborative Switching Strategy

In this article, the control scheme and switching strategies are studied for a dual three-phase hybrid permanent-magnet alternating current (PMAC) motor drive. Both high-coercive-force permanent magnets NdFeB and low-coercive-force permanent magnets AlNiCo are mounted on the rotor in order to provide high torque density and adjustable flux for electrical machine. The asymmetric dual three-phase windings can share the large currents for...
