In order to reducing number of elements and increasing voltage gain in renewable energy systems, the multi-input converters are used. In this paper, a new soft switching multi-input boost converter is presented. In the proposed converter number of extra elements that be used to achieve soft switching is reduced and only one auxiliary switch is used. The main switches are turned on and off at zero voltage switching conditions, and the auxiliary switch is turned on and off at zero current switching conditions. This converter is analyzed, and its operating modes are explained. Design considerations for the proposed converter is presented in the paper. The simulation and experimental results for a 200 W prototype converter confirm the theoretical analysis.

具有零电压开关的新型双输入升压转换器

为了减少可再生能源系统中的元件数量和增加电压增益，使用了多输入转换器。在本文中，提出了一种新的软开关多输入升压转换器。在提议的转换器中，用于实现软开关的额外元件数量减少，并且仅使用一个辅助开关。主开关在零电压开关条件下导通和关断，辅助开关在零电流开关条件下导通和关断。分析了该转换器，并解释了其操作模式。论文中介绍了所提议转换器的设计注意事项。200 W 原型转换器的模拟和实验结果证实了理论分析。
