Abstract
A bottleneck in optimization procedures of magnetic components is the calculation of the electric field strength (e.g. for an optimized insulation design) since this is based either on a slow numerical field simulation or on rough approximations. Hence, a fast and accurate method for the electric field calculation in the winding window is crucial for a fast optimization process. This paper presents a novel electric field calculation method that combines a variable potential function with a Schwarz-Christoffel (SC) mapping. This leads to accurate results, that match Finite Element Method (FEM) simulations as close as 5 %. The proposed method is more than 200 times faster than FEM and robust against parameter changes.
