摘　　要：多功能并网逆变器不但能完成常规并网逆变器实现可再生能源并网的基本功能,而且还复合了治理电能质量问题的功能,可以显著提高并网逆变器的性能价格比、降低系统的体积和成本,尤其适合于微电网和分布式发电系统应用。针对多功能并网逆变器的拓扑进行了综述。从单相和三相系统的角度阐释了多种多功能并网逆变器拓扑,并从系统参数、容量、开关频率、复合功能和应用场合等方面对各拓扑进行了比较和评价,并认为新型电力电子拓扑、先进控制策略、软开关技术、大功率应用以及电力电子集成系统中的稳定性等将会是多功能并网逆变器未来可能的研究方向。The multi-functional grid-connected inverter not only reahzes the grid-connection ot CtlStnbutect energy sources,but also improves the power quality. With higher performance-price ratio,it lowers the system cost and size,more suitable for the microgrid and distributed generation system. Its topologies are overviewed from the aspects of single-phase and three-phase systems, and compared and evaluated in view of system parameter, capacity, switching frequency, auxiliary function, application, etc. The novel topologies, advanced control strategies,soft switching technique,large power applications,integrated power-electronic system stability,etc, are considered as its possible future research fields.
