摘要: A motor driving apparatus and a control method thereof, including a dc-link capacitor configured to store DC power, an inverter including a plurality of switching elements and converting the DC power stored in the dc-link capacitor into AC power to output the power to a motor, a dc-link resistor element disposed between the dc-link capacitor and the inverter; and a controller configured to control an operation of the inverter. The controller calculates a phase difference between a first reference voltage vector among a plurality of reference voltage vectors that are preset on the space vector and a voltage command, generates a switching frequency, determines a first operating point located in a dead band that is a one-phase current undetectable area in one switching cycle and a second operating point located at an outer position including a boundary of the dead band, and controls operation of the plurality of switching elements.
