This paper presents a novel approach for measuring losses in magnetic components intended for medium-frequency power electronic applications. The proposed method enables accurate determination of core losses in power inductors using only voltage and current measurements. Real inductors, consisting of a copper litz winding and low-loss core, are used to test the effectiveness of the method across multiple operating points. The estimation method is able to match the losses with 6.13% accuracy, showing that it is sufficient with only voltage and current measurements, and is efficient in estimating the losses with low overhead.
