Abstract :
[en] In this work, the error made by frequency domain homogenization of windings in 2-D
magnetodynamics is quantified. To that end, the homogenized fields are combined with the analytical
solutions (a) of eddy currents flowing in a circular conductor placed in a uniform alternating magnetic
induction (proximity effect) and (b) of current density in conductors with non-zero net current (skin
effect). They are then compared to the fields from the fine model, taken as reference. It is shown that
error on resistance can reach 10\% at high frequencies for magnetic components with a limited number of
turns. Procedures to improve winding R, L parameters estimation from homogenized solution are introduced.
