摘　　要：在采用两个甚至多个输入源的新能源联合供电系统中,用单个多输入直流变换器MIC代替原有的多个单输入直流变换器,可以简化电路结构,降低系统成本。MIC可分为无缓冲单元和带缓冲单元的两类,文中讨论了无缓冲单元的MIC电路拓扑的生成方法。首先给出构成无缓冲单元的MIC电路拓扑的基本单元,提出生成MIC时基本单元之间的组合级联规则,由此推导出一系列无缓冲单元的MIC电路拓扑。In the renewable energy power system with two or more sources, the application of multiple-input converter（MIC） instead of several single-input converters can simplify the circuit and reduce the cost of the power system. MIC can be categorized into two lists, MIC without buffer cells and MIC with buffer cells. In this paper, a new method for synthesizing MICs without buffer cells is proposed. By analyzing the topologies of the single-input DC-DC converters, the basic cells of MIC are proposed. According to the presented synthesizing rules, a series of MICs without buffer cells are generated.
