Abstract
A method includes configuring a motor drive system with a motor/generator with a plurality of windings and coupling the plurality of windings to an inverter, configuring a plurality of active harmonic planes in a controller of the inverter to control a torque through controlling a magnetizing component and/or a torque component of winding currents on each active harmonic plane, and inserting a smooth transition between a first operating mode and a second operating mode of the motor/generator such that on at least one of the plurality of active harmonic planes, the magnetizing component of the winding currents changes in a sinusoidal fashion during the smooth transition.
