Abstract
A power supply apparatus for applying a method of supplying a loading with an electric power within a predetermined range of a default power, which includes a driving unit, a voltage sensing unit, and a feedback control unit. The driving unit receives power from a power source, and supplies the loading with a working voltage and a working current; the voltage sensing unit detects the working voltage; the feedback control unit keeps a plurality of reference voltages, wherein each two neighboring reference voltages are defined to have a voltage section therebetween. The feedback control unit sends a current signal to the driving unit according to the working voltage and a slope parameter of the voltage section which the working voltage falls in, and the driving unit supplies the working current according to the current signal to maintain the electric power in the predetermined range of the default power.
