<p><P>PROBLEM TO BE SOLVED: To provide a power conversion apparatus for supplying power stably regardless of the amount of natural energy, such as wind power. <P>SOLUTION: The power conversion apparatus 101 includes a rectifier circuit 11 including a rotary machine rotated by the natural energy and rectifying an AC voltage received from a power plant generating an AC power by rotation of the rotary machine, a plurality of voltage conversion circuits 13 to 15 that convert voltage rectified by the rectifier circuit 11 to a DC voltage at a prescribed level, supply the converted DC voltage to a load, and are composed so that either the minimum voltage that can be input and the maximum voltage that can be input, or the minimum current that can be input and the maximum current that can be input become large in order, and a voltage conversion control unit 12 for selectively operating the plurality of voltage conversion circuits 13 to 15 based on the AC voltage received from the power plant. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
