DIRECT-CURRENT POWER SUPPLY UTILIZING SYSTEM AND DIRECT-CURRENT MICROGRID NETWORK UTILIZING SAME

摘要

A direct-current power supply utilizing system includes: at least one direct-current power supply that produces a direct-current output; an alternating-current commercial power supply; a direct-current converter that converts the alternating-current commercial power supply into direct-current power; and a direct-current load device that receives supply of direct-current power from both at least one direct-current power supply and the commercial power supply which has been converted into direct-current power, where a back-flow prevention diode is individually connected between the at least one direct-current power supply and the direct-current load device and between the direct-current converter and the direct-current load device, and a power supply priority supply device that preferentially supplies power to the direct-current load device from the side of the direct-current power supply is connected.
