Influence of Non-Linearity in Losses Estimation of Magnetic Components for DC-DC Converters [PDF]
Energies, 2021 In this paper, the problem of estimating the core losses for inductive components is addressed. A novel methodology is applied to estimate the core losses of an inductor in a DC-DC converter in the time-domain. The methodology addresses both the non-linearity and dynamic behavior of the core magnetic material and the non-uniformity of the field ...
