Abstract
A power supply system includes a switching power supply configured to rectify and smooth an AC voltage of an AC power to generate a DC voltage, a controller configured to control the switching power supply to start or stop operating, and a low-capacity power supply comprising a power supply capacity smaller than that of the switching power supply. The low-capacity power supply is configured to supply power to the controller. The power supply system can further include a detecting circuit configured to detect an output voltage of the low-capacity power supply, and a permission circuit configured to permit a startup of the switching power supply when the output voltage detected by the detecting circuit is greater than or equal to a predetermined value.
