摘　　要：多端口直流变换器(multi-port DC/DC converters,MPC)可应用于新能源供电系统与电动汽车供电系统,它将系统中原有的多个单向和双向直流变换器在电路结构上实现合并,具有结构简单、成本低、控制灵活等优点。对现有的MPC进行分类,指出每种类型变换器的特点。从基本的双向直流变换器中提取出双向单极性脉冲电源单元,提出采用脉冲电源单元和缓冲单元组合的方法构建MPC,给出脉冲电源单元组合规则及其与缓冲单元的级联规则,总结归纳出5种不同类型多端口变换器的生成规则,进而推导出一系列MPC拓扑。Multi-port DC/DC converters（MPC） can be combined with multiple uni-directional DC/DC converters and bidirectional DC/DC converters into one configuration,which are of potential interest in applications such as renewable power systems and electric vehicle power systems,featuring simpler structure,lower cost and more flexible control.In this paper,available MPC were classified into different types,and the characteristics of each type were illustrated.The unipolar pulsating source cells（UPSC） were extracted from the conventional bidirectional converters;the approach to construct MPC with UPSC and buffer cells was proposed;and corresponding rules for combination and cascade of PSCs and buffer cells were given.Finally,five synthesizing rules for MPC were generalized and a series of MPC topologies were derived.
