1. A power source system, which is configured to receive an electric power from a power generation apparatus having a varying output, and to output the electric power which is received to a converter, and the power source system comprising:
a power storage device, configured to store the electric power of the power generation apparatus, and to discharge the electric power which is stored; a first switch portion, provided on a wiring line connecting the power generation apparatus and the converter; a second switch portion, provided between a point between the power generation apparatus and the first switch portion on the wiring line, and the power storage device; and a control unit, configured to control a connection or disconnection operation of the first switch portion and the second switch portion, wherein the control unit is configured to:
disconnect the first switch portion and connect the second switch portion, so as to perform a charging to the power storage device with the electric power output from the power generation apparatus, when an output current of the power generation apparatus is a low current; andcontrol the connection or disconnection operation of the first switch portion and the second switch portion, so that each of the first switch portion and the second switch portion is put into a connected state to output the electric power stored in the power storage device to the converter, when a voltage of the power storage device becomes higher than an operating voltage of the converter as a result of the charging. |
