要約(英語): The calculation of eddy current losses in foil windings exposed to a 2-D fringing field is a complex task because of the current displacement along the height of the foil. For model-based optimization of magnetic components, loss calculation with 2-D finite element method simulation is not an option because of the high computational effort. The existing alternative calculation methods with low computational effort, rely on approximations applicable only to a certain geometrical arrangement of the windings and the air gap. Therefore, in this study, a new semi-numerical method was developed to overcome these limitations. The method is based on the mirroring method and is applicable to arbitrary air gaps and winding arrangements. The accuracy of the new method was verified by measurements, and the deviation of the model results from the measured losses was found to be below 15%.
