Abstract
A power supply system includes: a switching power supply configured to convert an AC voltage from an AC power supply into predetermined DC voltages, and outputs the DC voltages; a switch circuit provided on an AC input line, the switch circuit being configured to be switched on and off and supply AC power to the power supply when the switch circuit is turned on; a low-capacity power supply circuit connected. to the AC input line at a front stage of the switch circuit, the low-capacity power supply circuit being configured to supply electric power to the switch circuit if the power supply is active and supply predetermined electric power if the power supply is not used; and a control device configured to receive the predetermined electric power from the low-capacity power supply circuit. When the power supply is not used, the control device turns off the switch circuit.
