Abstract:
The present disclosure relates to a method and an apparatus for managing an input power supply of an electronic device. A method for managing an input power supply of an electronic device according to one embodiment 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 a preset fundamental wave table; calculating at least one of an index value and an index variance with respect to the input power supply using a difference value between the input voltage and the approximate fundamental wave; and determining a kind of the input power supply on the basis of at least one of the index value and the index variance. In accordance with the present disclosure as described above, there is an advantage in which a kind of the input power supply may accurately be determined for a short time without affecting controlling of basic functions of the electronic device.
