Even for litz wire conductors consisting of the same amount of strands, the frequency-dependent power losses on system level differ significantly between different bundle structures. The multi-scale problem consisting of electromagnetic effects in the dimension of microns which influences a power electronic system on macroscopic level has been examined by a coupled simulation approach based on the FEM and PEEC method. Common PEEC approaches have been adapted to highly complex litz wires by enhanced mathematical methods for sparse-matrices. The simulation results have been verified by measurements up to 1 MHz.
