Abstract: A control device controls an operation of an electric motor, which is rotated by an electric power supplied from a battery. The control device includes an inverter, a controller and a booster. The inverter includes switching elements. The inverter converts an electric power supplied from the battery and supplies the converted electric power to the motor. The controller is operated by the electric power, which is supplied from the battery, to control the operation of the inverter. The booster boosts the voltage, which is inputted from the battery, and the booster outputs the boosted voltage to the controller. In a case where the voltage of the electric power supplied from the battery to the controller is dropped, the electric power, which has the voltage boosted by the booster, can be inputted to the controller.

Abstract: A motor control system includes: a power supply; a converter; an inverter; an alternating-current motor; and a control unit that drives the motor in any one of sinusoidal PWM control, overmodulation control and rectangular wave control through operation control of the converter and the inverter. The control unit starts step-up operation of the converter when a current vector of motor current of the motor on a d-q coordinate plane becomes a current phase corresponding to motor torque, at which a system loss is equal between before and after starting the step-up operation, while the control unit supplies the direct-current voltage, supplied from the power supply, to the inverter without stepping up the direct-current voltage by the converter and performs the rectangular wave control of the motor in a state where the current phase is an optimal current phase.
