摘　　要：随着新能源的开发和利用,多输入直流变换器(Multiple-input converter,MIC)以其电路结构简单、元器件数量少而越来越受到关注。本文提出了一种单原边绕组电压型多输入全桥变换器,该电路拓扑的变压器只有一个原边绕组,与传统多输入变换器相比较具有结构简单,元器件数量少,既可以单独向负载供电又可以同时向负载供电等优点。本文详细阐述单原边绕组电压型全桥MIC的拓扑生成方法、控制方式和特点,并以单原边绕组双输入全桥变换器为例,分析其工作原理和控制策略,最后通过原理样机进行实验验证。With the development and utilization of new energies, multi-input converter （MIC） has attracted more and more attentions due to its simple circuit structure and small number of components. This paper presents a kind of multi-input full bridge voltage converter with a single primary winding. Compared with traditional MIC, it has the advantages of simple circuit structure, small number of components, capability of separate and simultaneous supplies to the load, etc. Its topology generation, control methods and features are described in detail. An example of two-input full bridge voltage converter with a single primary winding is taken with the analysis of its working principle and control strategy, and the prototype test it passes.
