1. A power supply apparatus with a standby power cut-off structure, the power supply apparatus comprising:
a power supply unit configured to:
receive external power supplied through a plug to convert the external power to power suitable for a power supply target apparatus, andgenerate its own operation power of the power supply apparatus, the power supply unit including the plug connected to an outlet to receive the external power; a connector unit including:
a power supply terminal connected to a connection terminal of the power supply target apparatus to supply power to the power supply target apparatus, anda switching unit configured to establish or block an electric conduction of a power supply path through which the external power is provided to the power supply unit by a drive of a solenoid according to a switching driving signal provided from the power supply unit and a mechanical movement according to the drive of the solenoid, the switching unit being installed in the corresponding power supply path between the external power and the power supply unit; and a cable configured to connect the power supply unit and the connector unit, wherein the power supply unit is further configured to:
identify a supply state of power provided through the switching unit,output the switching driving signal to the switching unit when it is determined, through the identified supply state, that a battery of the currently connected power supply target apparatus is fully charged and/or a power supply is turned off, andallow the switching unit to cut off the power supply. |
