Title
(KO) 모터 제어 장치 및 모터 제어 장치의 제어 방법
Abstract
(EN)
The present specification relates to a motor control apparatus and a control method thereof, and more particularly, to a motor control apparatus and a control method thereof, capable of reducing harmonics of an input current by controlling the output of an inverter. The motor control apparatus includes an input unit for rectifying AC power inputted from the outside to DC power; a smoothing unit for smoothing the rectified DC power; an inverter unit for converting the smoothed DC power into the AC power and outputting the AC power to the motor; and a control unit for controlling a switching operation of the inverter unit.
