Abstract

Summary: Multi‐input converters (MICs) play an important role in integrating the independent energy sources utilized in the grid‐connected system and electric vehicle applications. In this scenario, several types of MICs are presented in the literature. Most of the MICs are operated using a time‐sharing scheme. This leads to a restricted duty cycle which limits the energy source utilization and output voltage. To overcome the above‐mentioned limitations, a multi‐input single‐output converter is proposed. The utilization of energy sources and output voltage can be improved with a reduction in the part count. A 400 W prototype is designed to check the feasibility of the proposed system, and the subsequent simulation and experimental results are validated.
