1. A motor-driving apparatus for driving a motor having a plurality of windings corresponding to a plurality of phases, respectively, comprising:
a first inverter including a plurality of first switching devices and connected to first ends of the plurality of windings;
a second inverter including a plurality of second switching devices and connected to second ends of the plurality of windings;
a third switching device including a plurality of switching devices; and
a controller configured to adjust an on/off state of the first to third switching devices based on a required output of the motor,
wherein:
the plurality of switching devices have first-side ends respectively connected to the specific points of the plurality of windings, and second-side ends connected to each other,
when the required output of the motor is greater than a preset reference value, the controller is configured to turn off the third switching device and drive the motor by performing pulse-width modulation control on the first switching device and the second switching device, and
each of the plurality of switching devices corresponds to different one of the plurality of phases.
