一种太阳能与市电混合供电装置设计与实现

The Design of Power Supply Equipment of Solar Energy and Commercial Power

文章介绍一种新型的供电装置,该装置由太阳能电池及其检测电路、蓄电池及其检测电路、单片机、充电电路等组成.它能充分利用太阳能,并在太阳能供电不足时自动转为市电供电,解决长期阴雨天情况下太阳能供电不足的问题.

In this paper, we will introduce a new power supply equipment. The system＇s circuit inlcueds four modules, i.e., the circuit of solar cells and it＇s detection circuit, the circuit of storage battery and it＇s dection circuit, microcontroller, the circuit of charging. The system can make full use of solar energy. The system supply power by commercial power when the solar energy is faint, then the problem of insufficient electricity supply is sloved when it＇s cloudy and rainy.
