A reliable analysis of Ferrite Core (FC) inductors operating with moderate saturation is a fundamental requirement in the design of high-power-density switch-mode power supplies. This paper discusses the application of a Pulse Compression procedure to identify the Hammerstein model of the saturation characteristic of FC inductors.

Abstract

A reliable analysis of Ferrite Core (FC) inductors operating with moderate saturation is a fundamental requirement in the design of high-power-density switch-mode power supplies. This paper discusses the application of a Pulse Compression procedure to identify the Hammerstein model of the saturation characteristic of FC inductors. The ability of the modeling approach to obtain a reliable model of non-linear FC inductors is tested through simulations in a case of practical interest, with comparisons to a literature behavioral model and its Taylor and Padé numerical approximations.
