Abstract
A motor driving apparatus of driving a motor including a plurality of windings respectively corresponding to a plurality of phases is disclosed. The motor driving apparatus includes a first inverter including a plurality of first switching elements and connected to a first end of each of the windings, a second inverter including a plurality of second switching elements and connected to a second end of each of the windings, and a controller electrically connected to the first switching elements and the second switching elements and configured to generate limited pole voltage commands for space vector pulse width modulation based on preset voltage commands of the motor and to distribute the limited pole voltage commands to generate first pole voltage commands for switching of the first switching elements and second pole voltage commands for switching of the second switching elements.
