摘　　要：直流微电网是未来智能配用电系统的重要组成部分,对推进节能减排和实现能源可持续发展具有重要意义.其中DC-DC变换器是解决直流微网、分布式电源、储能装置等接入主电网的重要技术基础.分析了储能型非隔离双向DC-DC变换器的拓扑结构和数学模型,总结了5种DC-DC变换器的技术特点以及在直流微网中的应用,最后对直流微网的发展趋势和技术难题进行了讨论.DC microgrid is an important part of the future intelligent power distribution system,which is of great significance to promote energy saving and emission reduction and realize the sustainable development of energy. DC-DC converter is an important technical basis for the DC microgrid,distributed power,energy storage devices to get access to the main power grid. In this paper,the topological structure and mathematical model of energy-storage non-isolated bidirectional DC-DC converters are analyzed. Then,the technical characteristics of five DC-DC converters and their application in DC microgrid are summarized. Finally,their development trends and technical problems are discussed.
