Abstract
A plug for a DC appliance includes an input unit including anode and cathode terminals, an output unit including anode and cathode terminals to allow a DC current input through the input unit to be output to an electric device, a connection unit to interconnect the input unit and the output unit, a rectifier unit coupled between anode and cathode terminals of the input unit to rectify the input DC current, an inductor unit connected in series to the rectifier unit so that an internal current of the plug is gradually increased in response to an increase of the input DC current, and a condenser unit connected in series to the inductor unit, which is charged with voltage in response to a current passing through the inductor unit, and discharges the charged voltage to the output unit when the input of the DC current from the input unit is interrupted.
