摘　　要：化石燃料(煤、油等)排放温室气体,是污染大气环境的主要原因。大量发展可再生能源可保护大气环境、并在社会经济发展中起主要作用。清洁的可再生能源包括:水力和风力、太阳光伏和燃料电池、生物质能、海洋能等。太阳能光伏(Photo Voltaic)系统,将太阳光能转换为电能,技术上已较成熟。主要优点是:不排放有害气体、无温室效应、无噪音、可靠、寿命长等,是一种清洁的可再生能源。主要应用于为城乡住宅、荒漠地区供电,也可联网为工业供电。在无电或缺电地区,光伏和风力、微型透平发电可组成离网混合分布式电力系统。本文简要介绍光伏发电系统的发展进程、国内外发展概况、电力电子技术在光伏系统中的应用等。Fossil fuels are major cause of environmental destruction in pollutions. It has created much needed momentum for renewable energies, such as hydro, wind, solar, geothermal, biomass, fuel cell （hydrogen）, ocean, etc. Photo Voltaic （PV） turns energy produced from the sun light into electricity as so called solar power source, which is a sustainable source of energy, enabling 100% renewable, zero emissione-reliable and quiet electricity production. The historical evolution, the state of the art and developing trends, and classification of the Photo Voltaic （PV） power technologies are presented in this paper. Power electronics playing an important role in the utilization of the solar PV light energies are also introduced.
