Abstract Accurate understanding of losses and frequency‐dependent winding parameters have been an important aspect for selecting the right configuration of stranded conductors in power‐electronic inductors. An approach for modelling frequency‐d

Finite element analysis of transformers with stranded conductors can be computationally heavy due to the fine mesh required for winding domains. In this paper, a domain decomposition method with subdomain pre-processing is proposed to overcome with t
