Multi-input converters play an important role in integrating the independent energy sources utilized in the grid-connected system and electric vehicle (EV) applications. In this scenario, several types of multi-input converters 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 sources utilization and output voltage. To overcome the aforementioned limitations, a multi-input single-output (MISO) boost converter is proposed. It can improve the utilization of energy sources and output voltage with a reduction in the part count. To verify the feasibility of the proposed scheme, a 200 W prototype circuit is developed; simulation and experimental results are validated. © 2023 The Authors.
