Title:
UNINTERRUPTIBLE SOLAR POWER GENERATION SYSTEM
Document Type and Number:
Japanese Patent JP3216969
Kind Code:
B2
Abstract:
PURPOSE: To obtain an uninterruptible solar power generation system in which the power generated from a solar battery and commercial power can be utilized effectively and consumption of commercial power can be reduced.
CONSTITUTION: A solar battery 1, a battery 3 and a charge/discharge circuit 12, and a commercial power supply 2 and a rectifier 4 are connected through a capacitor 11 with a load 6. When the terminal voltage of capacitor 11 is higher than the output voltage of rectifier 4, the rectifier 4 is not operated. When the terminal voltage of capacitor 11 is lower than the output voltage of rectifier 4 and the voltage of commercial power supply is higher than a predetermined level, the rectifier 4 is operated. When the terminal voltage of capacitor 11 is lower than the terminal voltage of battery 3, the charge/ discharge circuit 12 is operated.
