摘要： A motor driving apparatus that drives a motor including a plurality of windings respectively corresponding to a plurality of phases, may include 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 including a current controller to produce, based on a predetermined current command of the motor, a voltage command for determining a switching duty of the first switching elements and the second switching elements, wherein the current controller is configured to produce a zero-phase component voltage command among the voltage commands by applying 3rd harmonic feedforward compensation.
