| Abstract |
In this paper a method to calculate the thermal resistance of windings is presented and validated bymeasurements. Two formulas have been developed for widely used wire types in power electronicsbeing round and litz wire. With the presented approach it is possible to describe the thermal resistanceof arbitrary wire arrangements. This analytical approach can either be used in fast forward designs ofmagnetic devices, respectively can also be integrated in automatized optimization procedures to improvethe designs of magnetic components. The calculated results are showing good coincidence with themeasured values. |
