摘　　要：直流微网是一种连接分布式电源与主电网的微网形式,双向DC-DC变换器(BDC)作为直流微网中必不可少的接口电路,在直流微网中充当着重要的角色,能够有效提升分布式电源利用率和直流微网的电能质量。在简要阐述学者们关于直流微网结构研究成果的基础上,归纳出了BDC在直流微网中的四方面典型应用。主要呈现了面向直流微网的BDC研究成果,着重分析了直流微网中应用BDC作为接口电路的变换器拓扑选择。最后,基于研究现状的分析,结合直流微网的发展趋势和电力电子关键技术对BDC未来的技术发展进行了讨论。DC micro-grid is a grid form integrating distributed energy systems with utility powersystems. As the indispensable interface circuits, bidirectional DC-DC converters （BDC） play animportant role in DC micro-grids. It can effectively improve the distributed energy utilization ratio aswell as the performance and quality of DC micro-grids. After the brief introduction of DC micro-gridsystem architectures, the four typical applications of BDC in DC micro-grids are classified andaggregated. This paper concludes the current research achievements, and focuses on the applications ofBDC in DC micro-grids. Finally, the future development tends of BDC are discussed on the view of DCmicro-grid development trends and the key technologies of power electronics.
