A motor driving apparatus includes a motor driving unit for converting DC voltage on a DC link into AC voltage when a switching device is turned on/off and outputting the AC voltage to an AC motor side, a gate driving circuit for turning on/off the switching device, a gate driving command generation unit for outputting either one of an ON command and an OFF command to the gate driving circuit, and an overcurrent detection unit for detecting an overcurrent with respect to a DC link current or an alternating current on the AC motor side, wherein, when the overcurrent detection unit detects the overcurrent, the gate driving command generation unit alternately outputs the ON command and the OFF command while gradually increasing a ratio of the OFF command to the ON command and ultimately outputs only the OFF command.
