摘要
在光伏发电系统的可靠性方面,逆变器是整个系统中的关键环节也是薄弱环节,为此进行了一系列对逆变器可靠性的研究。为了给逆变器设计者提供更多的可靠性研究信息,文章综述了逆变器可靠性的研究现状。文章揭示了影响光伏发电系统可靠性的关键环节,介绍了影响逆变器可靠性的各种因素,从拓扑结构、组成元器件、可靠性设计以及IGBT模块的寿命预测等方面进行了对比分析,最后讨论了逆变器可靠性研究所面临的问题和挑战。
In the photovoltaic power generation systems reliability, inverter is a key link in the whole system is also a weak link, therefore made a series of research on the reliability of the inverter. To provide inverter designers with more information on the reliability of the research, the article summarizes the research status of inverter reliability. Article reveals the influence key link in the process of photovoltaic power generation system reliability, this paper introduces the factors affecting the reliability of the inverter, the topology structure, composed of components, reliability design and life prediction of IGBT module and so on has carried on the contrast analysis, finally discusses the problems and challenges facing inverter reliability research institute.
