Abstract

A power supply system includes: a switching power supply to be connected to an AC power supply, the switching power supply rectifying and smoothing an AC voltage to generate predetermined DC voltage; a first capacitor including a first electrode connected to one end of the AC power supply, and a second electrode; a second capacitor including a first electrode connected to the other end of the AC power supply, and a second electrode; a surge-voltage suppressing circuit connected between the second electrode of the first capacitor and the second electrode of the second capacitor; a rectifier circuit connected to a first contact node between the first capacitor and the surge-voltage suppressing circuit and a second contact node between the second capacitor and the surge-voltage suppressing circuit; and an output-signal generating circuit connected to the rectifier circuit, and uses the rectified current to generate a predetermined output signal.
