An accuracy assessment of 2-D vs. 3-D finite element models for ferrite core, sheet wound transformers

This study examines the parameter estimates for representative high frequency transformer designs with a view to assessing the errors that might be expected when 2-D approximate finite element models are used for the purpose of parameter extraction. The assessment has been based on a comparison of parameter estimates obtained from the 2-D models, relative to values predicted by fully converged 3-D models. The study has shown that the widely used 2-D models provide parameter estimates that, at worst, are in the order of 25% greater than the 3-D results. In many instances, the agreement is found to be much closer than that.
