Non-linear inductor modelling for a DC/DC Buck converter


G. Lullo, D. Scirè and G. Vitale




The paper is focused on the modelling of an inductor to exploit its non-linear behaviour in the roll-off region when it is employed in a DC/DC converter. The model is set up on the basis of experimental data measured in operating conditions, which are fitted to a polynomial curve describing the
inductance variations. The analysis of the buck converter, performed by including the proposed model, is validated by experimental tests.
