In this paper, we discuss about the accuracy and robustness of a time domain model for the analysis of soft ferrite core inductors, particularly applicable in the design of power converters. The model is based on the division of the magnetic field into three components, which are suitably defined on the basis of the static and dynamic behavior of a magnetic material and are identified by experimental data. A detailed description of the model and the obtained results are presented in the paper. The results obtained are also compared with the ones calculated from different approaches, known in literature. The model is applied to the prediction of losses and peak current of a family of ring shape core inductors.
