A New Dual Input Boost Converter with Zero Voltage Switching

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.
