Semi-numerical method for loss-calculation in foil-windings exposed to an air-gap field
- Conference Paper
The calculation of Eddy current losses in foil windings exposed to a 2-D fringing field is a complex task, due to the current displacement along the height of the foil. For model based optimization of magnetic components, the loss calculation with a 2-D FEM simulation is not an option, due to the high computational effort. The existing alternative calculation methods, which allow for loss calculation with low computational effort, rely on approximations applicable only for a certain geometrical arrangement of the windings and the air gap. Therefore, a new semi-numerical method is 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 is verified by measurements and the deviation of the model to the measured losses is below 15%. Show more
