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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
