Abstract:
PROBLEM TO BE SOLVED: To provide a power supply device capable of suppressing shortening of life of a power storage unit resulting from an increase in burden on the power storage unit.SOLUTION: This power supply device 1 includes a plurality of AC/DC 10, a power storage unit 20 connected between a load 220 and the AC/DC 10 and storing DC power converted by the AC/DC 10, and a control unit 40 controlling the power storage unit 20 on the basis of an input of AC power input to the plurality of AC/DC 10, rated power of the load 220, and the amount of load power of the load 220. Then, in the case where some of a plurality of commercial power supply systems 200 have made a stop, and in the case where the total sum of DC power output from the plurality of AC/DC 10 is smaller than the amount of load power, the control unit 40 exerts control of supplying electric power from the commercial power supply systems 200 or from the commercial power supply systems 200 and the power storage unit 20, to the load 220.SELECTED DRAWING: Figure 1
