Abstract: An appliance includes a driver to drive a load, the load requiring AC power or DC power. A power supply receives one of external AC power, back-up AC power and back-up DC power and outputs at least one of AC power or DC power to the load. An operation mode of the home appliance is one of normal operation when receiving external AC power, normal operation when receiving one of back-up AC power and back-up DC power during a power interruption, and a power save mode when receiving one of back-up AC power and back-up DC power during the power interruption. The power supplies a first power level when there is no power interruption, a second power level when there is power interruption and a third power level when there is power interruption and the power save mode is selected, where the second power level is between the first power level and the third power level. The power save mode is automatically selected when the second power level falls below a reference power level.
