摘要

PROBLEM TO BE SOLVED: To solve the problem that output voltage by which output power of a solar battery becomes maximum cannot often operate the solar battery.

SOLUTION: An output voltage control unit controls output voltage of a parallel connection circuit. A maximum value search part searches for maximum value of synthesized output power including output power of a first power supply and output power of a booster circuit. A maximum value search control unit causes the maximum value search part to search for maximum value while causing the output voltage control unit to change output voltage of the parallel connection circuit every first voltage value, increases output voltage of the parallel connection circuit just for second voltage value greater than the first voltage value after a predetermined period passes, and then causes the maximum value search part to search for maximum value while causing the output voltage control unit to change output voltage of the parallel connection circuit every first voltage value.
