The isolated dc-dc converter along with energy storage is becoming a promising solution in versatile applications including renewable energy based micro grids, solid state transformers, hybrid electric vehicles, fuel cell and so on. Bi-directional power flow capability and galvanic isolation are considered as prime requirements of a Bi-directional Energy Harvester Interface (BEHI). This paper presents operational principles, simulation/implementation and comparison of an isolated BEHI using Double Active Bridge (DAB) and Isolated Boost Mode Full Bridge (IBMFB) configurations.
