Abstract
This work presents a multi‐input converter (MIC) that can build a DC microgrid having renewable energy resources, balanced sources, and energy storage devices. After analysing its operation modes, a design procedure for the converter considering three different cases is provided. This procedure includes the semiconductor elements selection and design of the inductors. After this step, a detailed efficiency analysis is carried out for the studied cases. Finally, a 1 kW prototype creating a photovoltaic–battery system is built. Through several experiments based on this set‐up, it is shown that the theoretical analysis is accurate and the studied MIC can be successfully utilised to create DC microgrid.
