<P>PROBLEM TO BE SOLVED: To provide a power conversion device for inputting the power of a plurality of DC power supply sources each of which is connected between function units and which have different output characteristics, while independently controlling the output of a voltage regulator and the output of an inverter connected to the rear stage thereof. <P>SOLUTION: The power conversion device includes a maximum power follow-up control circuit 5 for regulating the power of the DC power supply source using a voltage regulating means 2a; inputting the output of the voltage regulating means to an inverter means 7 to convert it into AC power; and regulating the input/output voltage ratio of the voltage regulating means 2a, to follow the maximum power of the DC power supply source, and an output voltage control circuit 6 for controlling the output voltage in priority to the maximum power follow-up control circuit 5 so that the output voltage does not exceed predetermined maximum link voltage. The inverter means 7 uses an output power control circuit 14 for controlling input power to be a predetermined input operating voltage which is set to be a value lower than the maximum link voltage. <P>COPYRIGHT: (C)2009,JPO&INPIT |
