Classification: CPC H  Y | IPC H

Claim 1:
2. The apparatus of claim 1, wherein the controller comprises:
a current command map configured to generate a current command based on preset power required for the motor;
a current controller configured to generate a voltage command of the motor by comparing the generated current command and a value to detect a current supplied to the motor to reduce a difference between the current command and the value;
a first duty generator configured to generate a voltage command of the first inverter by multiplying the voltage command of the motor by ½ times, and to convert the voltage command of the first inverter into a phase voltage command of the first inverter, and to generate the first offset voltage command based on the phase voltage command of the first inverter; and
a second duty generator configured to generate a voltage command of the second inverter by multiplying the voltage command of the motor by −½ times, and to convert the voltage command of the second inverter into a phase voltage command of the second inverter, and to generate the second offset voltage command based on the phase voltage command of the second inverter.
