<P>PROBLEM TO BE SOLVED: To reduce a loss in the power generation amount of a solar battery due to steep change in solar radiation. <P>SOLUTION: A control device of a solar power conversion unit comprises: power detection parts (41, 42) for detecting the output power of a solar battery (20); a solar radiation input part (46) to which an index indicating the solar radiation is input; a power correction part (47) for correcting an output power detected by the power detection parts (41, 42), based on the index indicating the solar radiation input to the solar radiation input part (46); and a voltage control part (45) for changing the output voltage of the solar battery (20) such that the output power of the solar battery (20) approaches a maximum power point, based on the output power corrected by the power correction part (47). <P>COPYRIGHT: (C)2012,JPO&INPIT |
