1. An inverter driving apparatus comprising:
an inverter including a plurality of legs corresponding to a plurality of phases; and
a controller configured to generate a plurality of pole voltage commands from a plurality of space vector modulation signals corresponding to each of the phases and to modulate the plurality of pole voltage commands through pulse width modulation to control a turn-on state of switches included in the plurality of legs,
wherein the controller is configured to generate a plurality of discontinuous modulation signals by applying an offset voltage for discontinuous modulation to each of the space vector modulation signals in response that at least one of a maximum voltage and a minimum voltage of the plurality of space vector modulation signals is not included in a predetermined linearity range, to adjust at least one of a maximum voltage and a minimum voltage of the plurality of discontinuous modulation signals, and to output the adjusted discontinuous modulation signals as the plurality of pole voltage commands.
