abstract

  • This paper presents the numerical comparison in ANSYS Maxwell between nanocrystalline, Vitroperm 500F, and ferrite, 3C90, cores to be used in power electronic converters (PECs) transformers. The converter topology used is the doubled switch Forward, due to its characteristics and its power range (<500W). The transformer model development, the characterization and the BH measure curves from the material, as well as its validation and the excitation type implemented in the numerical model are described in the methodology. The exposed results show an improvement in comparasion with the ferrite, in addition to a better flexibility in the magnetic design methodology, given by the nanocrystalline magnetic characteristics.
