Errors obtained when 1D magnetic component models are not properly applied

Since 1D magnetic component models are widely used, it is very important to understand the range of their application. This work presents an analysis of 1D magnetic component models in order to study their range of application. The errors that can result when these models are not properly applied have been quantified. Therefore, the results of this work provide the designer with information about the accuracy of the simulations when using 1D magnetic component models. Several simulations have been performed which compare 1D and 2D models and provide the reasons for the discrepancies in each particular case.
