Medium Frequency Transformer Design with Ārtap Framework

Nowadays, there is a huge interest in the design of medium frequency transformers. Due to their high power density and relatively good efficiency. These transformers are still used in wind farms and traction, where not only the efficiency, but the overall size and weight of the transformer are important design criteria. However, the determination of the load losses is based on analytical or pseudo-empirical formulations during the design optimization process. In this paper, an open-source robust design optimization framework process based medium frequency transformer design process is introduced. During the solution of this process, the magnetic field is calculated directly by the builtin FEM solver.
