Title:
DC POWER SUPPLY SYSTEM AND RECTIFIER
Document Type and Number:
Japanese Patent JP2015231327
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dc power supply system and rectifier capable of making effective use of surplus power by photovoltaic power generation while suppressing an increase in equipment cost.SOLUTION: A dc power supply system 1 includes: a rectifier 2 for generating a direct current; a storage battery 3; and a photovoltaic power generation device 4. The photovoltaic power generation device 4 can supply surplus power of generated power to the storage battery 3. The rectifier 2 adjusts an output voltage of the rectifier 2 so that a voltage of the storage battery 3 when SOC of the storage battery 3 is a predetermined target charge amount meets an output voltage of the rectifier 2.
