Claim 0:
1. A motor drive device configured to drive a motor having a plurality of windings respectively corresponding to a plurality of phases, the motor drive device comprising:
a first inverter including a plurality of first switching elements, and connected to a first end of each of the plurality of windings;
a second inverter including a plurality of second switching elements, and connected to a second end of each of the plurality of windings; and
a controller configured to generate phase voltage commands of the first inverter and phase voltage commands of the second inverter based on preset voltage commands of the motor, wherein the phase voltage commands of the first inverter and the phase voltage commands of the second inverter are respectively represented as vectors of different angles,
wherein the first inverter and the second inverter convert DC power stored in a battery into AC power and provide the AC power to the motor.
