Abstract

Several studies have proved that the use of Ferrite Core (FC) power inductors operating in moderate saturation allows volume and weight of Switch-Mode Power Supplies (SMPSs) to be reduced. Thus, a reliable analysis of non-linear FC inductors operating in moderate saturation is fundamental for the design of high-power-density SMPSs. This paper suggests the application of a Pulse Compression procedure for the Hammerstein model identification of the inductance versus current characteristic of FC inductors. The proposed approach allows a reliable model of FC inductors to be obtained up to moderate saturation non-linearity. Several simulations in cases of practical interest are presented, with comparisons to an established literature behavioral model and its Taylor and Padé numerical approximations.
