Abstract
A motor driving apparatus and a home appliance including the same. The motor driving apparatus includes a temperature sensing unit to sense a compressor temperature, an inverter including a plurality of switching elements to convert a direct current (DC) voltage into an alternating current (AC) voltage and to supply AC voltage to a motor used to drive the compressor, and a controller to control the inverter. The controller performs control to apply motor preheating current for preheating of the motor during a first period before startup of the motor, and varies depending on the sensed temperature a time during which the motor preheating current is applied or a current application level. A reduction in power consumption during the preheating of the compressor is achieved.
