S. Ehrlich, H. Rossmanith, M. Sauer, C. Joffe, M. März, Fast Numerical Power Loss Calculation for High-Frequency Litz Wires, IEEE Transactions on Power Electronics 36 (2021) page 2018

The paper received a 2021 IEEE Transactions on Power Electronics First Place Prize Paper Award.

It 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 external magnetic fields (proximity losses). Calculations of complex litz wires were performed and have been validated by measurements. In the calculation, the impact of the bundle structure on skin and proximity losses is examined. The method allows one to select a suitable litz wire for a specific application or to design a litz wire considering realistic twisting structures.
