<P>PROBLEM TO BE SOLVED: To provide a power conversion apparatus that supplies generated power of power generation means formed from at least one of a solar battery 1, a fuel battery 2 and a wind power generator 4 to a commercial power supply system 15 and implements power conversion for charging a storage battery 2 with the power generation means and the commercial power supply system 15, by switching a circuit for common use of a reactor L1 and switching means Tr1, Tr3 for step-up and step-down. <P>SOLUTION: The power conversion apparatus includes: a voltage conversion circuit 101 having a reactor L1 through which a current from power generation means runs from the primary side to the secondary side, and interruption switching means Tr1, Tr3 for performing voltage conversion by controlling electric conduction into the reactor L1; a DC-AC conversion circuit 10 that performs DC-AC conversion on an output of the voltage conversion circuit 101 for output to a commercial power supply system 15; and circuit changeover switching means SW1-SW5 that selectively guide the current running through the reactor L1 inside the voltage conversion circuit 101 to a storage battery 2 side or to the commercial power supply system 15 side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
