Abstract

Power generating elements output electromotive force. A path switching unit switches a path for connecting arbitrary power generating elements among the power generating elements. A voltage converting unit is a DC-DC converter that converts voltage levels of outputs of some of the power generating elements. A path switching control unit controls the path switching unit such that a set of power generating elements where a sum of maximum power point voltages falls within a range of an appropriate charging voltage of a storage element is connected to a short-circuit path and the other power generating elements are connected to a transformation path. A voltage conversion control unit controls a transformation rate of voltage conversion in the voltage converting unit such that a voltage in the transformation path and a voltage in the short-circuit path become equal to each other.
