In this paper, a model for nonlinear ferrite power inductors based on the αNet neural network is proposed.

The modeling procedure can be easily extended to inductors with different sizes and core materials due to the features of the αNet network and the hybrid approach to retrieve data.

Abstract
In this paper, a model for nonlinear ferrite power inductors based on the αNet neural network is proposed. The model is able to reproduce the ferrite power inductors inductor behavior up to saturation, considering the core temperature. The αNet neural network was used for its generalization capability considering a hybrid approach encompassing a classical weighted interpolation. The model’s effectiveness was experimentally verified by calculating the current flowing through two inductors in an electric circuit in different operating conditions, and has been compared with the two main models found in literature to show the improvement both in terms of the maximum value of the estimated current and the root mean square error. The modeling procedure can be easily extended to inductors with different sizes and core materials due to the features of the αNet network and the hybrid approach to retrieve data.File | Dimensione | Formato | |
