<P>PROBLEM TO BE SOLVED: To provide an electricity control device, an electricity control method, and an electricity supply system capable of performing control so as to maintain a maximum operating point of an electricity generating element, such as solar battery and of avoiding electricity losses. <P>SOLUTION: The electricity control device includes an electricity path switch unit 32, to which a plurality of electricity generation elements 20-1 and 20-2 can be connected, and a voltage transformer unit 31 for transforming a voltage level which is supplied via the electricity path switch unit 32 and is generated by the electricity generating elements. The electricity path switching unit 32 includes a first connection switching function for switching between series connection and parallel connection of the plurality of electricity generating elements and a second connection switching function for switching between connection and non-connection to the input side of the voltage conversion unit, of the electricity generating elements that are connected in series or in parallel. <P>COPYRIGHT: (C)2011,JPO&INPIT |
