Abstract
Provided are a DC power supply device and a DC power supply system for supplying multiple DC powers having variable voltages using a power line communication (PLC). The DC power supply device includes an AC/DC converter, a DC/DC distributor, a plurality of output voltage regulators, a voltage control module, and a PLC modem. The AC/DC converter converts an inputted AC voltage into DC voltage, and the DC/DC distributor distributes the DC voltage according to number of external devices. The output voltage regulators output the distributed DC voltage to the external devices. The voltage control module controls the output voltage regulators to output voltages according to the voltage request information of the external devices. The PLC modem transmits/receives the real-time voltage request information of the external devices through a power line.
