<p>The purpose of the present invention is to improve power conversion efficiency of a power converter for a solar panel while, minimizing fluctuations. The power supply system is provided with: a solar power generation device; a first power converter connected at the direct current side to the solar power generation device; a solar power generation system having capacitors connected in parallel between the solar power generation device and the direct current side of the first power converter; a plurality of second power converters respectively connected in series at the alternating current side; and a control device that controls an electric storage system having an electric storage device connected to each of the plurality of second power converters at the direct current side thereof, and that controls the first power converter and the plurality of second power converters. The system synthesizes voltage generated at the alternating current side of the first power converter and voltage generated at the alternating current sides of the second power converters, and supplies power to a system through a reactor. The control device changes the output voltage ratio of the solar power generation system and the electric storage system.</p> |
