Power control apparatus for solar power generation system

摘要

A power control apparatus for supplying a load with power output by a solar cell comprises converting means for converting output power of the solar cell to power conforming to the load; first sensing means for sensing output power of said converting means; second sensing means for sensing output voltage and output current of the solar cell; setting means for setting operating voltage of the solar cell based upon the sensed output voltage and output current of the solar cell; and control means for controlling the output voltage of the solar cell by controlling operation of said converting means based upon the set operating voltage and sensed output power of said converting means. As a result, excessive power is prevented from being output by the power control apparatus.
