Abstract
An inverter driving device includes an inverter including a plurality of legs corresponding to a plurality of phases, and a controller that generates a plurality of pole voltage commands from a plurality of space vector modulation signals corresponding to the plurality of phases and modulates the pole voltage commands through pulse width modulation to control a turn-on state of switches included in the legs, wherein the controller is configured to generate a plurality of discontinuous modulation signals by applying an offset voltage for discontinuous modulation to the plurality of space vector modulation signals if at least one of a maximum voltage and a minimum voltage of the space vector modulation signals is not included in a predetermined linearity range, adjusts at least one of a maximum voltage and a minimum voltage of the discontinuous modulation signals, and outputs the adjusted discontinuous modulation signals as the pole voltage commands.
