This article presents a fast numerical calculation method of realistic power losses for high-frequency litz wires. Explicitly, the imperfect structure of litz wires is considered when calculating losses due to an excitation current (skin losses) and

Due to the necessary minimization of the magnetic stray field generated by power electronic circuits the various ways on PCB-level to reduce these stray fields become more and more important. Therefore in the context of a laboratory for power electro

The proximity losses in high-frequency transformers strongly depend on size and position of the air gaps as well as on the position of the turns inside the winding area. This paper demonstrates the analytical calculation of the two-dimensional field
