  • Patent number: 11711045
    Abstract: An electric motor drive device controls driving of a motor having open windings of two or more phases having end points that are open to each other. The switching arbitrator determines switching between a single-sided and dual-sided drive mode and arbitrates output of each of the inverters at a time of switching wherein output of the motor is continuous before and after the drive mode switching. The single-sided drive mode is a mode in which one of the two inverters performs switching drive. The dual-sided drive mode in which both the two inverters perform switching drive. The switching arbitrator gradually changes and increases the power level of the drive-start-side inverter from zero when the single-sided drive mode is switched to the dual-sided drive mode, and gradually changes and decreases the power level of the drive-end-side inverter to zero when the dual-sided drive mode is switched to the single-sided drive mode.
