Power electronics transformers (PETs) have better application in smart grid because they have more advantages than conventional transformers with a structure integrating the power electronic equipment and medium frequency transformers (MF transformers). As an important part of PET, the MF transformer undertakes significant functions of voltage conversion, energy transfer and electrical isolation. Its performance determines the efficiency and reliability of the overall system. This paper mainly discusses design procedure and efficiency optimization of MF transformers. The method of computing leakage inductance is also presented to achieve the series resonance. Finally the optimal MF transformer prototype is validated with finite element simulation.
