Description

一种太阳能逆变器
技术领域
本发明涉及太阳能发电系统技术领域,尤其是涉及一种太阳能逆变器。 
背景技术
随着我国光伏发电应用规模与范围的不断扩大,光电市场对逆变器的需求量迅速增加。与此同时,高质量、低成本的逆变器产品逐渐成为光电系统开发人员和广大用户所关注的问题。逆变器是电力电子技术的一个重要应用方面。电力电子技术是电力、电子、自动控制及半导体等多种技术相互渗透与有机结合的综合技术。因此,逆变器所涉及的知识领域和技术内容十分广泛, 
近年来,随着“小家电”产品的日益增多,愈来愈多的人在使用可充电电池,许多家庭都备有小型蓄电池充电器。充电器的核心部件是整流器,它的功能是将50周波的交流电整流成为直流电。逆变器与整流器恰好相反,它的功能是将直流电转换为交流电。这种对应于整流的逆向过程,称之为“逆变”。太阳电池在阳光照射下产生直流电,然而以直流电形式供电的系统有很大的局限性。例如:日光灯、电视机、电冰箱、电风扇等均不能直接用直流电源供电,绝大多数动力机械也是如此。此外,当供电系统需要升高电压或降低电压时,交流系统只需加一个变压器即可,而在直流系统中升降压技术与装置就要复杂得多了。因此,除特殊用户外,在光伏发电系统中都需要配备逆变器。逆变器还具有自动调压或手动调压功能,可改善光伏发电系统的供电质量。综上所述,逆变器已成为光伏发电系统中不可缺少的重要配套设备。
