Power supply device, and control method of power supply device

Abstract

A power supply device according to an embodiment comprises a plurality of power sources 10 each including an antenna and an AC/DC conversion unit, a plurality of consolidating units 13—1 to 13—i, and a power supply unit 15. The consolidating units 13—1 to 13—i respectively include consolidating circuits 14—1 to 14—i that selectively consolidate a plurality of DC signals 21—1 to 21—n supplied by the plurality of power sources 10. The power supply unit 15 includes a consolidating circuit 16 that selectively consolidates the DC signals 21—1 to 21—i output from the plurality of consolidating units 13—1 to 13—i, and a voltage conversion circuit 17 that converts a DC signal 23 resulting from consolidation in the consolidating circuit 16, to a predetermined voltage.
