Abstract

A power supply system includes: a switching power supply and a rectifying/smoothing circuit, the switching power supply configured to output a first output voltage in a normal output mode; a step-down circuit; a control device that controls the switching of the switching power supply between the normal output mode, a low output mode, and an off mode; and an electric storage unit charged by the output of the step-down circuit in the normal output mode and supplies power to the control device in the off mode, wherein, when charging is needed in the mode other than the normal output mode and the low output mode, the control device controls the switching power supply to output the third output voltage, thereby charging the electric storage unit.
