Abstract:
A motor controller is provided that includes an inverter configured to drive an electric motor, a rectifier configured to rectify an alternating current (AC) input current and to output the rectified AC input current to the inverter, and a controller coupled to the inverter. The controller is configured to improve a power factor of the motor controller by controlling the AC input current based on a direct current (DC) link voltage measurement.
