Abstract
A power supply device having a standby power cutoff structure, comprises: a power supply unit which has a plug connected to a socket, converts an external power for a power supply target device, and generates self-operating power; a connector unit which includes a power supply terminal to supply power to the power supply target device, and opens or blocks a power supply path between the external power and the power supply unit in response to a switching driving signal received from the power supply unit; and a cable for connecting the power supply unit and the connector unit, wherein the power supply unit checks the state of power supplied through a switching unit to output the switching driving signal to the switching unit such that the switching unit cuts off a power supply when the power supply target device is fully charged or the power supply device is turned off.
