家用太阳能光电系统控制器

The Regulator Applied in Household Solar PV System

我国家用太阳能光电系统已占太阳能光电系统销售总量的 40 % ,而照明是家用电器中最基本的用电器。本文阐述了家用太阳能光电系统控制器设计工作中应考虑的一些问题 ,着重讨论了可靠性设计原则以及各种蓄电池充、放电保护电路的工作原理和各自的特点。介绍了具有代表性的两种家用太阳能光电系统控制器的实例。

The regulator is usually applied in household solar PV system,which accounts for about 40% of the total amount of installed solar PV system now in our country.The lights are one of the most essential domestic appliances used in the solar PV system.The paper presents on some measures in design of the regulator,especially in design of reliability.It focuses in the battery overcharging protect circuits and the battery overdischarging protect circuit.The working principle and main features of the different types of the protect circuits are respectively discussed.The circuit diagrams of two typical regulators are also given in the paper.
