Abstrakt:	The paper presents the concept of a medium frequency transformer built with thin grain oriented electrical steel (GOES) sheets and high temperature windings; this transformer will be associated with power converters for building a solid-state transformer (SST) used in DC grids. The aim of the study is to bring answers about the maximum operating frequency and flux density that provide the maximum power density and efficiency. A thermal model built from tests on the prototype is presented. This thermal model gives a prediction of the transformer performance for the initial choices of frequency and flux density. It opens perspectives for designing high power density medium-frequency (MF) transformers. [ABSTRACT FROM AUTHOR]
