Abstract

This paper proposes a multiphase converter topology with an innovative PWM strategy for the control of a PM synchronous motor with segmented stator windings to operate as an electronic geared motor. Simulation studies of the segmented PMSM with configurable stator windings have been carried out. Compared with conventional three-phase inverter topology, the proposed converter topology with associated PWM modulation strategy has advantages of reduced conduction loss, improved efficiency under light load condition, and expanded torque-speed operating ranges with a same dc-link voltage. The interleaved PWM strategy provides advantages of ripple current reduction and conduction losses reduction. Simulation results have been given to show advantages and flexibility of the proposed multi-phase PWM control scheme for a PMSM with segmented windings.
