ABSTRACT:
In order to prevent a device serving as a load from being destroyed or causing an operation error while assuring an optimum operation voltage of a solar cell, and to stably, efficiently obtain power, a DC source system, in which a solar cell (1) and a DC source (3) are connected to an output terminal connected to a load (2) in parallel with each other, includes a first switch (5) arranged between the load (2) and the solar cell (1), a second switch 7 arranged between the load (2) and the DC source, and a capacitor (6) arranged between the load and the first switch in parallel with the solar cell.
