<P>PROBLEM TO BE SOLVED: To increase the use efficiency of converters. <P>SOLUTION: A two-way power conversion apparatus 10 of distributed power supply equipment 4 comprising step-up/down converter devices 11, 21 connected in parallel, has a first power input/output section (junction Pc1) capable of power input/output and a plurality of second power input/output sections (junctions Pc2,3) capable of power input/output, and converts power input from the first power input/output section or second power input/output sections to a preset voltage value to be output to the second power input/output sections or first power input/output section. A selector switch SW1 switches to connect the first power input/output section to either a DC power generation apparatus 2 or a storage battery 3, and selector switches SW2, SW3 switch power transmission paths to connect the second power input/output sections to either an AC power system 6 or the storage battery 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
