Title:
DC VOLTAGE CONVERSION CIRCUIT AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/225418
Kind Code:
A1
Abstract:
Provided are a DC voltage conversion circuit capable of converting a DC voltage by means of a simple configuration and control, and a power supply system. The DC voltage conversion circuit (1) includes a DC voltage selection circuit (10), an inductor (30), and a rectification circuit (20). The DC voltage selection circuit (10) electrically connects a plurality of voltage input portions (TM1 to TMN), to which a plurality of mutually different DC voltages are supplied, to a converging node (NDM) in a time-divided manner. The inductor (30) is connected between the converging node (NDM) and a voltage output portion (TMout). The rectification circuit (20) is connected between a reference node (NDref) to which a reference voltage is supplied and the converging node (NDM).
