Title:
SYSTEM USING DIRECT-CURRENT POWER SOURCE, AND DIRECT-CURRENT-TYPE MICROGRID NETWORK USING SAME SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/046244
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is particularly to provide a system using a direct-current power source, capable primarily of priority supply of direct-current power from a solar cell, and maximizing utilization of generated electric power from the solar cell even when the amount of solar irradiation has changed. [Solution] The present invention is characterized in comprising at least one direct-current power source for outputting a direct current, an alternating-current commercial power source, a direct-current converter for converting an alternating-current commercial power source to a direct-current power source, and a direct-current load for receiving a direct-current supply of power from at least one direct-current power source and both commercial power sources converted to direct current, a backflow prevention diode being attached each between at least one direct-current power source and the direct-current load and between the direct-current converter and the direct-current load, and a power source priority supply device being attached for performing priority supply of power to the direct-current load from the direct-current power source side.
