    • The present invention provides a power supply apparatus which can suppress a raising and hunting of output (DC voltage) to a load which is light. The power supply apparatus comprises an AC-to-DC converter for supplying a load with a DC voltage, and a switching operation controller for correcting a power factor and controlling a switching element so that an output or a DC voltage of the AC-to-DC converter becomes a predetermined target value. The switching operation controller has a low-pass filter for smoothening the DC voltage with a variable cut off frequency. By varying the cut-off frequency of the low-pass filter, it is possible to recognize a rising of the DC voltage to suppress and stabilize a boost and hunting of the DC voltage in a light load state.
