<P>PROBLEM TO BE SOLVED: To provide a power conversion apparatus capable of attaining reduction in the number of components and more significant cost reduction. <P>SOLUTION: The power conversion apparatus 100 includes: a reactor L1 through which a current from a solar battery 1 runs from a primary side to the secondary side; a voltage conversion circuit 9a with interruption switch means that controls energization into the reactor L1 for voltage conversion; a DC-AC conversion circuit 10 that implements DC-AC conversion to an output of the voltage conversion circuit 9a for output to a commercial power supply system 15; circuit changeover switching means SW1-SW3 that selectively guide the current which runs through the reactor L1 in the voltage conversion circuit 9a from the primary side to the secondary side to a battery 2 side or the commercial power supply 15 side; and a motor 4 with a coil that permits a magnetic flux to run through a magnetic circuit therein. The reactor L1 is formed from a coil of the motor 4. Thus, the power conversion apparatus 100 can use a coil forming the reactor L1 in common. <P>COPYRIGHT: (C)2012,JPO&INPIT |
