Resumen : With the current trend towards greener energy sources, the integration of Energy Storage Systems (ESS) is the key to sustain the grid against fluctuations of energy generation. This raises a major concern for the inclusion of an efficient, fully controllable power conversion stage to allow an intermediate processing of energy flow. The Dual-Active-Bridge (DAB) converter provides full controllability as well as galvanic isolation. DC-DC Isolated conversion is a critical process in some applications such as Electric (EV) and Hybrid Electric Vehicles (HEV). Also linking ports up in a Multi-port DAB converter via multiport transformer allows for the integration of additional energy sources to the system. This converter can thus be employed in applications ranging from a front-end converter in points of common coupling at facilities, to a high power modular structure used on distribution system levels. The motivation behind the thesis is to study the Dual-Active-Bridge bidirectional dc-dc converter topology, and validate its operation for a 2kW rated power setup. A starting approach for the design procedure, covered in this work, is to employ the converter as a unidirectional power flow converter, supplying a load that resembles the behavior of a typical micro-grid, such as a resistance in parallel with a DC link. Thus, the operation of the converter at rated power can be analyzed, studied and optimized.
