【摘要】 光伏发电系统主要由光伏电池板、变换器、控制器、蓄电池和负载等构成。由于光伏电池板所转化的电能与光照强度有关,而光照强度在一天中的变化很大,所以其转化的电能很难直接供给负载使用,这就需要由电力电子器件构成的变换器对电能进行变换,变成适合负载使用的电能。另外,在系统充电、放电以及逆变等环节加入变换器,可以实现多种不同的控制方法,为提高系统的整体效率带来可能。本文主要对光伏发电系统中的直流变换电路进行介绍和研究。更多还原

【Abstract】 Photovoltaic generating system consists of the solar panels,converter,controller,battery,load and so on. For the reason that the energy transformed by solar panels is related to the light intensity,and light intensity vary greatly during the day. It is difficult to directly supply electricity to the load,which requires the converter making up by the power electronic devices to transformed electrical energy into electrical energy suitable for the load. In addition,by adding converter to the system’s charge,discharge,and other sections,we can get a variety of different control methods,thus to improve the overall efficiency of the system. This paper focuses on the introduction and research of D.C. converter circuit in photovoltaic generating system.更多还原
