Motor driving apparatus and home appliance including the same

A motor driving apparatus, comprising:

• a direct current (DC)-stage capacitor to store DC power;
• an inverter including three-phase upper arm and lower arm switching elements, the inverter to convert, based on a switching operation, the DC power from the DC-stage capacitor to an alternate current (AC) power, and the inverter to output the converted AC power;
• a controller to control the inverter, wherein the controller is configured to control the switching elements, and the controller is configured to control a turn-on time of the switching elements;
• an output current detector to detect an output current in a motor,
• wherein the controller is configured to:
• provide a voltage command value based on the output current in the motor,
• determine a position of a voltage vector based on the voltage command value,
• when the position of the voltage vector is within a first region of a space vector area and any one of the three-phase switching elements in the inverter is continuously turned on during a first switching period and a second switching period contiguous to the first switching period, control others of the three-phase switching elements in the inverter to shift turn-on time in a direction to a boundary between the first switching period and the second switching period during the first switching period and the second switching period, and control all the three-phase switching elements in the inverter to turn on during a first period including the boundary between the first switching period and the second switching period,
• when the position of the voltage vector is within a second region different from the first region of the space vector area and any one of the three-phase switching elements in the inverter is continuously turned off during the first switching period and the second switching period, control others of the three-phase switching elements in the inverter to shift turn-on time in the direction to the boundary between the first switching period and the second switching period during the first switching period and the second switching period, and control at least one of others of the three-phase switching elements in the inverter to turn on during a second period including the boundary between the first switching period and the second switching period.
