Claim 0:
1. A motor driving apparatus configured to drive a motor having a plurality of windings respectively corresponding to a plurality of phases, the apparatus comprising:
a first inverter comprising a plurality of first switching elements and connected to a first end of each of the plurality of windings of the motor;
a second inverter comprising a plurality of second switching elements and connected to a second end of each of the plurality of windings of the motor; and
a controller configured to control pulse width modulation, by distributing a preset voltage command of the motor into a voltage command of the first inverter and a voltage command of the second inverter at the same rate and by generating duties of the first switching elements and duties of the second switching elements, wherein the controller determines the duties of the second switching elements based on a first offset voltage command generated based on a phase voltage command of the first inverter and determines the duties of the first switching elements based on a second offset voltage command generated based on a phase voltage command of the second inverter.
