摘要：An object of the present invention is to prevent a failure of a power feedingdevice easily at low cost. A power supply apparatus includes a conversion unit (110) thatconverts a first AC voltage into a first DC voltage by rectifying a first AC voltage, andsmoothing the first DC voltage. The smoothing unit (120) that generates the second DC
voltage including the ripple voltage, the monitoring unit (130) that monitors the secondDC voltage (P6), and the second DC voltage and the allowable voltage range arecompared A determination unit (140) that determines the deterioration degree of thesmoothing unit (120) based on the comparison result, and an input control unit (150) thatcontrols the AC voltage input to the conversion unit (110) based on the deteriorationdegree And.
