Abstract
An inverter driving apparatus includes an inverter having a plurality of legs respectively corresponding to each of a plurality of phases and the control unit generating space vector modulation signals based on a phase voltage command, each of the space vector modulation signals corresponding to each of the plurality of phases, respectively, determining whether an output voltage of the inverter corresponding to at least one space vector modulation signal of the space vector modulation is in a non-linear region by determining whether each voltage of the space vector modulation signals is included in a predetermined range, generating a terminal voltage command by determining whether or not to apply an offset voltage to each of the space vector modulation signals based on the determination of the non-linear region, and controlling a turn-on state of at least one switch included in each of the plurality of legs by modulating the terminal voltage command based on pulse width modulation.
