Abstract
A method for managing an input power supply of an electronic device includes measuring an input voltage that is input from an input power supply; generating an approximate fundamental wave with respect to the input voltage using a maximum value of the input voltage and values of a fundamental wave; calculating at least one of an index value or an index variance with respect to the input power supply using differences between the input voltage and the approximate fundamental wave; and identifying a type of the input power supply based on the at least one of the index value and the index variance. When the input power supply is identified as an uninterruptable power supply, the electronic device may be controlled to operate in a minimum power consumption mode.

A method comprising:
- measuring an input voltage from an input power supply to an electronic device;
- generating a fundamental wave based on a maximum value of the input voltage and preset fundamental wave values;
- calculating at least one of an index value or an index variance with respect to the input power supply using one or more differences between the input voltage and the fundamental wave;
- and
- identifying a type of the input power supply based on the at east one of the index value or the index variance.
An apparatus comprising:
- a measuring sensor configured to measure an input voltage from an input power supply to an electronic device;
- a fundamental wave processor configured to generate a fundamental wave based on a maximum value of the input voltage and preset fundamental wave values;
- an index processor configured to calculate at least one of an index value or an index variance with respect to the input power supply using a difference value between the input voltage and the fundamental wave;
- and
- a controller configured to identify a type of the input power supply based on the at east one of the index value or the index variance.
