Abstract
A motor control device that controls driving of a first inverter and a second inverter each configured to control a supply current to a three-phase alternating-current motor. The motor control device is configured to: switch a control mode between a single-inverter control mode in which one of the first inverter and the second inverter is driven to control the supply current to the motor, and a twin-inverter control mode in which both the first inverter and the second inverter are driven to control the supply current to the motor; calculate each of a first power loss due to the single-inverter control mode and a second power loss due to the twin-inverter control mode; and set the control mode to the first power loss or the second power loss, whichever has a smaller power loss.
