Abstract

A first DC/DC converter is of a constant voltage control type and is controlled so as to keep the voltage of an electric generation bus at a predetermined target value. A second DC/DC converter is of a constant current control type and is controlled so as to keep input current or output current at predetermined target current. A control circuit determines an optimum target value of electric generation bus voltage, based on different algorithms, in accordance with all or some of modes A to C which are classified by the charging/discharging condition of a second electric storage device, and controls the first DC/DC converter so that the electric generation bus voltage becomes the determined target value.
