電力供給装置
Document Type and Number:
Japanese Patent JP6923121
Kind Code:
B2
Abstract:
To provide a power supply device that can supply power by maintaining maximum output operation voltage of a solar battery that can always maintain voltage of a place taking-out power from the solar battery at voltage of a maximum power point, without adding a solar battery panel or a switching mechanism of a storage battery.SOLUTION: A power supply device comprises: a charging/discharging device input/output unit 2 that connects between a DC input unit 1 from a DC power generator and a DC charging/discharging device; a maximum power point acquisition unit 4 that detects a maximum power point of the DC power generator or a maximum power point neighborhood; a power synthesis unit 3 that synthesizes power from the DC power generator with power from the DC charging/discharging device; and a power supply unit 5 that supplies power to a load. The power supply device is characterized to have a conversion unit 6 that can perform bidirectional power distribution to and from the charging/discharging device input/output unit 2 and the power synthesis unit 3, between itself and the charging/discharging device input/output unit 2 and the power synthesis unit 3.SELECTED DRAWING: Figure 1
