Analysis and experimental verification of a multi-input converter for DC microgrid applications

WOS: 000437312900006This 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 1kW 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.Scientific and Technological Research Council of Turkey-TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [113M088]This work is funded by The Scientific and Technological Research Council of Turkey-TUBITAK under grant no. 113M088
