    Abstract: The present disclosure relates to a motor driving device and a laundry treatment apparatus. The motor driving device may include an inverter to convert DC power into AC power according to a switching operation and to output the converted AC power to a motor, an output current detector to detect an output current flowing through the motor, and a controller to control the inverter based on the detected output current. The controller changes a carrier frequency, changes a voltage command based on the changed carrier frequency and outputs an inverter switching control signal to the inverter based on the changed carrier frequency and the changed voltage command. Accordingly, noise may be reduced during operation of the motor.
