Title: POWER SUPPLY SYSTEM, POWER SUPPLY DEVICE, AND CONTROL DEVICE
Abstract:
A power supply system 1 is provided with: a plurality of power supply devices 10-1 to 10-n connected in parallel, for supplying power to loads 3; and a control device 20 for notifying a plurality of variable resistances, which are determined on the basis of the current distribution ratio of the plurality of power supply devices, to the respective corresponding power supply device. The plurality of power supply devices 10-1 to 10-n respectively have: power converters 12-1 to 12-n that convert direct current power to alternating current power, and output the alternating current power to a load; and control units 13-1 to 13-n that control the output voltage of the power converters 12-1 to 12-n on the basis of the virtual resistances notified from the control device 20.
