Japanese Patent JP3330407

B2

PURPOSE:To feed the power to a radio frequency power supply system and an uninterruptible power supply system by one power supply apparatus for a building in which a commercial power supply system and a new distributed power supply system are interconnected to each other. CONSTITUTION:An uninterruptible power supply system 8 to which the AC power of a commercial power supply system 2 is supplied and a bidirectional inverter 7 which converts the AC power of the commercial power supply system 2 into a DC power to DC-interconnect the commercial power supply system 2 to a new distributed power supply system 3 and to a power supply storage apparatus 4 for emergency power feeding when the commercial power supply system is operated normally and converts the DC power from the new distributed power supply system 3 and from the power supply storage apparatus 4 into a commercial frequency AC power and supplies the power to the uninterruptible power supply system 8 when the service of the commercial power supply system 2 is interrupted are provided. Further, a radio frequency inverter 10 whose input side is connected to the DC side of the bidirectional inverter 7 and which is driven only when the commercial power supply system is operated normally and converts the DC power into a radio frequency power and a radio frequency power supply system 15 which is connected to the output side of the inverter 10 and to which the radio frequency AC power is supplied is provided.
