INDOOR DC POWER SYSTEM WITH A POWER COMMUNICATION LINE FUNCTION CAPABLE OF REDUCING ENERGY

摘要

PURPOSE: An indoor DC power system with a power communication line function is provided to prevent a power factor improving circuit from being shared at each electric appliance by comprising a DC voltage line via the power factor improving circuit and a DC voltage control unit.;CONSTITUTION: An integrated rectification circuit unit(221) converts an AC voltage from an AC voltage line into a DC voltage. An integrated power factor improving circuit unit(222) is connected to the output of the integrated rectification circuit unit and improves the power factor of the load. A DC voltage line(230) is wired from the power factor improving circuit to an outlet and an electric withdrawal terminal. An integrated power line communication system(240) performs DC power line communication by using the DC voltage line. An individual power line communication control unit(260) separates the power line communication control signal from the DC voltage.;COPYRIGHT KIPO 2012
