Résumé
This article presents the design of a three-port, three-phase Multi-Active Bridge converter. This converter aims to interconnect various renewable energy sources with electrical loads, using hydrogen as an energy storage medium for domestic applications. Photovoltaic panels will serve as the primary energy source; any excess energy produced will be stored as hydrogen using an electrolyzer. When the photovoltaic panels are unable to meet consumption needs, electrical energy will be generated from the stored hydrogen using a fuel cell. The Multi-Active Bridge consists of three three-phase inverters magnetically coupled through a transformer. The objective of this converter is to regulate the energy flow among the different components of the structure, operating through a ’phase-shift’ control method applied between the three inverters.
