Abstract

The present invention relates to a motor driving apparatus and a refrigerator including the same. A motor driving apparatus according to an embodiment of the present invention comprises: a signal delay unit for delaying an input speed order signal; an inverter control unit for outputting an inverter switching control signal, on the basis of the speed order signal delayed by the signal delay unit; and an inverter for converting an input operation direct current power into a predetermined alternating current power, on the basis of a switching operation according to the inverter switching control signal, and driving a motor using the converted alternating current power. Therefore, it is possible to prevent starting failure and reduce noise.
