Abstract
An apparatus and a method for power supply are provided. The apparatus for power supply includes a main power circuit, an auxiliary power circuit and a power switching control circuit. The main power circuit is configured to generate a main power suitable to be provided to a first load and a second load for use. The auxiliary power circuit is configured to generate an auxiliary power suitable to be provided to the second load for use. The power switching control circuit is configured to detect a voltage difference between the main power and the auxiliary power and determine whether the apparatus meets a normal power supply condition, so as to select one of the main power and auxiliary power as a power source of the second load.
