Abstract
A power supply system includes: a switching power supply operated in an on mode and an off mode; a mode controller for generating a pulse signal for designating the mode; an auxiliary power supply for feeding power to the mode controller; a power supply controller configured to be activated as the power is fed and to control an oscillation operation in accordance with the pulse signal generated by the mode controller; and a supply detector for detecting starting of the power feeding. The power supply controller executes: oscillating the switching power supply when the pulse signal is input during the oscillation stop; stopping the oscillation of the switching power supply when the pulse signal is input during the oscillation; and invalidating an input of the pulse signal for predetermined time when the supply detector detects the starting of the power feeding.
