Control Strategy of Dual Fed Open-End Winding PMSM Drive for Traction Applications

Abstract

This paper proposes a control strategy of open winding permanent magnet synchronous motor (OW PMSM) in field weakening and braking modes. There are two inverters connected to the start and end of motor windings with traction batteries which have equal voltage levels. Paper describes motor control algorithms, provides simulation of proposed topology in Matlab/Simulink software. Simulations provides trainset processes of motor in different regimes (accelerating and braking). Simulation results shows overall proposed topology performance.
