Abstract
A control system for an automatic shutdown of a power supply constructed with a switching mode power supply (SMPS) receiving an AC voltage and converting the AC voltage into a DC voltage; a main board receiving the DC voltage output from the switching mode power supply; and a control circuit controlling and maintaining the supply of power from the switching mode power supply to the main board until a shutdown process is performed when power is turned OFF, wherein the control system enables the automatic shutdown of a power supply while preventing a file or a system from being damaged by automatically cutting off power after performing the shutdown process by the power control system even though the power switch is turned OFF due to the carelessness of the user or an external factor.
