1. A motor driving apparatus comprising:
a motor including a plurality of windings respectively corresponding to a plurality of phases;
a first inverter including at least one first power module and configured to provide an alternating current (AC) voltage corresponding to each of the phases to a first end of the plurality of windings;
a second inverter including a plurality of second power modules each including a changeover switch and configured to provide the AC voltage corresponding to each of the phases to a second end of the plurality of windings based on information indicating whether the changeover switch is turned on; and
a controller connected to the changeover switch and configured to control whether the changeover switch is turned on according to a motor driving mode,
wherein each of the second power modules has a changeover terminal to which a first end of the changeover switch is connected,
wherein the changeover terminals of the plurality of second power modules are circuited connected to each other, and
wherein each of the second power modules further includes:
a second top switch;
a second bottom switch;
a positive terminal electrically connected to a positive terminal of a battery;
a negative terminal electrically connected to a negative terminal of the battery; and
an output terminal electrically connected to a second end of one of the plurality of windings,
wherein the second top switch is connected between the positive terminal and the output terminal, and
wherein the second bottom switch is connected between the negative terminal and the output terminal.
