| 摘要 | 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. | ||

| 主权项 | 1. A motor controller comprising: 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 said inverter; and a controller coupled to said inverter and 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 without sensing AC line current. | ||
