Losses within the ferromagnetic core are one of the main effects limiting the efficiency, power capacity and power density of electrical power transformers. Some of the promising newer technologies/materials used to realize the transformer core are still not so well understood and a proper characterization and standardization does not exist yet. In that respect, a proper characterization and modeling of the losses within the ferromagnetic core of a transformer is one of the essential tasks needed for a good design. To that end, this project deals with experimental testing, characterization, and modeling of the core losses. This research aims to generate a much-needed insight into the real behavior of ferromagnetic cores in exact conditions and geometry setups as encountered in transformers, thus properly exposing all the relevant effects. Finally, firm guidelines are to be established, defining the good and bad practices, allowing to achieve the most efficient transformer design for the given application. The duration of the internship is 6 to 12 months.
