Abstract
Power transfer in an electric motors including segmented windings utilize control commands. A control system determines a d-axis command voltage for a secondary winding of an electric motor and a q-axis command voltage for the secondary winding based on a primary winding voltage, primary winding current, secondary winding current, and rotor electrical position. The control system generates gate control signals based on the determined d-axis command voltage and q-axis command voltage for the secondary winding and transmits the gate control signals to an inverter coupled to the secondary winding to control an electrical power transfer between the primary winding and the secondary winding.
