Abstract:
The present disclosure relates to a motor driving apparatus and a home appliance including the same. The motor driving apparatus in accordance with an embodiment of the present disclosure, comprises a DC-stage capacitor, a three-phase upper arm and lower arm switching element, an inverter to convert DC power from the DC-stage capacitor to an AC power by a switching operation and output the converted AC power to a motor, and a controller to control the inverter, wherein the controller controls the switching elements in the inverter based on a space vector-based pulse width variable, and controls a turn-on time of the switching elements to be shifted, wherein continuous first and second switching periods of the switching elements is changed to one switching period by shifting the a turn-on time of the switching elements. Accordingly, when the inverter is switched, noise can be reduced while reducing switching loss.
