摘　　要：太阳能并网发电技术日益成为研究热点,并网逆变器作为光伏阵列与电网的接口设备,其拓扑结构决定着整个光伏并网发电系统的效率和成本,是影响系统经济可靠运行的关键因素.在简要介绍光伏并网逆变器常用拓扑方案基础上,重点分析了其有代表性拓扑结构的特点、效率及适用场所,并给出了并网逆变器拓扑结构未来可能的发展趋势.Photovoltaic （PV） grid-connected power system is becoming a hot research area. As the interconnection of the PV arrays and the power grid, the topology structure of the grid-connected inverter is very important. Because it determines the system efficiency, cost and reliability. The artof-the-state topologies for grid-connected power system was classified and introduced. Furthermore, the performance, the efficiency and the applications of the main grid-connected inverters were analyzed. At last, the future trend of the grid-connected inverters were given and summarized.
