Non-linear inductor modelling for a DC/DC Buck converter   G. Lullo, D. Scirè and G. Vitale   2017/04/25

Abstract

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.
