Influence of Non-Linearity in Losses Estimation of Magnetic Components for DC-DC Converters

In this paper, the problem of estimating core losses for inductive components is addressed. A novel methodology applied to estimate an inductor in a DC-DC converter time-domain. The addresses both non-linearity and dynamic behavior magnetic material non-uniformity field distribution device geometry. natively implemented using LTSpice simulation environment can be used include accurate behavioral model devices more complex lumped circuit. compared against classic estimation techniques such as Steinmetz Equation improved Generalized Equation. validation performed on practical Buck converter, which was utilized experimentally verify results derived by suitable losses. Both experimental test confirm accuracy proposed methodology. Thus, technique flexibly direct loss realization subsystem able simulate realistic within
