Power management apparatus and method thereof and power control system

Abstract: A power management apparatus includes: a service request monitor block for receiving service requests by service groups to provide load information of service platforms belonging to the respective service groups; a platform information collection block for collecting a configuration information of the service platforms and collecting load information of the service platforms in a predetermined cycle; a platform power state alteration block for altering power states of the service platforms by request; and a management interface block for providing a setup interface for a load-based and a time-based power control and providing platform profile information generated based on the load information.

Dc power supply device and metod for variable voltage multiple output using power line communication

Abstract: 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.
