DC POWER SUPPLY DEVICE AND METOD FOR VARIABLE VOLTAGE MULTIPLE OUTPUT USING POWER LINE COMMUNICATION

摘要

PURPOSE: A multiple variable outputting DC power supplying device is provided to implement efficient power management and power dispersion by controlling an output voltage and a power supply through a power line communication. CONSTITUTION: An AC/DC transformer(110) transforms an AC voltage to a DC voltage. A DC/DC dispersing unit(120) disperse the DC voltage. A plurality of output voltage regulators(130_1~130_n) supplies the dispersed DC voltage to an exterior device. A power line communications MODEM(150) receives a voltage request-information of the exterior device through a power line. A voltage control module(140) controls the output voltage regulator for outputting the output voltage corresponding to the voltage request-information of the exterior device.
