Abstract
A motor driving apparatus driving a motor that has a plurality of windings respectively corresponding to a plurality of phases 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 determining a voltage command of the first inverter based on a voltage command of the motor and the active vector corresponding to a duty of the second switching elements and controlling the first switching elements through pulse width modulation based on the voltage command of the first inverter.
