Power electronics transformers (PETs) have the advantages of small volume and light weight, so they have promising applications in rail transit traction systems substituting traditional transformers. The PET consists of the medium frequency transformer (MF transformer) and power electronic converters on the primary and secondary sides. Among these components, the MF transformer efficiency affects overall system power transfer capacity, and plays an important role as it determines whether the PET system could work with high performance. This paper aims at efficiency optimization of MF transformers and studies the relation between efficiency and core materials, operating parameters, and geometric parameters to give MF transformer designs some useful references.
