Abstract: A motor driving device is disclosed. The motor driving device includes: a rectifier rectifying alternating current (AC) power into direct current (DC) power to output an input voltage; a first buck-boost converter including a plurality of switches for converting the input voltage and having a buck mode of stepping down the input voltage and a boost mode of stepping up the input voltage; an inverter converting a DC-link voltage transformed from the first buck-boost converter into an AC voltage and transferring the AC voltage to a motor; and a controller receiving motor information related to driving of the motor, comparing magnitudes of a desired DC-link voltage depending on the received motor information and the input voltage with each other, and performing a control to switch only any one of the plurality of switches so that the first buck-boost converter is operated in the buck mode or the boost mode.
