Abstract
Disclosed is power supply device and method having a spark prevention function. The power supply device having a spark prevention function includes output connectors to which an external device is coupled to be supplied with electric power; and an output controller for controlling a level of a voltage outputted to the output connectors depending upon whether the external device is coupled to the output connectors. Accordingly, damages to parts and malfunctions due to spark occurrences can be prevented, so an external device can be coupled to a power supply device in operation without any damage.
