Title:

DC POWER SUPPLYING AND DISTRIBUTING SYSTEM

Document Type and Number:

WIPO Patent Application WO/2021/229803

Kind Code:

A1

Abstract:

This DC power supplying and distributing system comprises: a plurality of distribution lines (1, 2) respectively connected to a plurality of loads (21, 22); a first converter (3) that converts an AC voltage supplied from a commercial AC power supply (23) into a plurality of DC voltages (V2, V3), and supplies the plurality of DC voltages (V2, V3) to the plurality of distribution lines, respectively; a second converter (4) that converts a DC power supplied from a power generating and storing source (24) into a plurality of DC powers (P12, P13), and supplies the DC powers to the plurality of distribution lines, respectively; and a controller (11) that enhances the efficiency of the second converter by controlling the first converter so that a ratio (V2/V3) between the plurality of DC voltages is a predetermined first ratio (N3/N2).
