Abstract
A power supply system includes: a switching power supply configured to rectify and smooth an alternating current voltage of an alternating current power supply and generate a direct current voltage; a small-capacity power supply having a power supply capacity smaller than a power supply capacity of the switching power supply; a sensor configured to output a detection voltage corresponding to a detection target; and a control device. The control device comprises: a reference voltage generation circuit configured to be fed with power from the small-capacity power supply and generate a reference voltage, a comparison circuit configured to compare the detection voltage output from the sensor with the reference voltage and generate a comparison voltage corresponding to the comparison result of the comparison circuit, and a monitoring unit configured to monitor the detection target based on the comparison voltage during the switching power supply is stopped.
