摘要：

<P>PROBLEM TO BE SOLVED: To provide a power supply system capable of effectively utilizing electric power that a decentralized power source generates even when electric power supply from a commercial power system to a load is stopped. <P>SOLUTION: There is provided a power supply system 10 including: a first inverter 100 which converts a DC current generated by a PV power generation part 30 into an AC current, and operates as a voltage source to supply electric power to a load 70; a second inverter 200 which converts a DC current generated by an FC power generation part 40 into an AC current, and operates as a current source to supply electric power to the load 70; a PV connection switch 300 which switches an electric power line connecting the first inverter 100 and the second inverter 200 between a conductive state and a non-conductive state; and a control section 400 which electrically connects the electric power line to the PV connection switch 300 while electric power supply from a commercial power system 80 to the load 70 is stopped so as to make the second inverter 200 output the DC current to the first inverter 100 through the electric power line. <P>COPYRIGHT: (C)2013,JPO&INPIT
