INVERTER CONTROL DEVICE, INVERTER CONTROL METHOD THEREOF, AND VEHICLE INCLUDING SAME

An inverter control device is capable of reducing an inverter junction temperature by minimizing a maximum value of a phase current flowing through an inverter. The inverter control device includes a current command output module configured to output a current command corresponding to an input torque command, a current command conversion module configured to receive the current command and a zero sequence current command, and phase-shift the current command to output a phase-shifted current command, a switching determination module configured to output a control signal based on an input motor rotation speed and the torque command, and a switching module configured to selectively output one of the current command and the phase-shifted current command in response to the control signal.
