New Computationally Inexpensive Power Cancellation Concept for Magnetic Core Loss Measurement Agote San Sebastian, Anartz Arruti Romero, Asier Garmendia Garcia, Adei Aizpuru, Iosu Lefevre, Guillaume Core loss Ferrites Phase discrepancy is a major source of error in the measurements of core losses, so reactive cancellation techniques are used to improve the measurement accuracy. To do so, an air core transformer is introduced in the measurement setups. In this work, an alternative methodology for correction of the phase discrepancy is presented, which makes use of the air core transformer introduced in previous techniques. Unlike reactive cancellation techniques, whose objective is to reduce the reactive voltage in the core under test, the proposed method directly addresses the phase discrepancy based on the fundamental assumption that there are no core losses on an air core transformer. The proposed methodology does not rely on Fast Fourier Transform algorithms, which minimizes the required computational resources for the post-processing of the measured waveforms. 2026-05-28T14:03:49Z 2026-05-28T14:03:49Z 2025 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=201101 https://hdl.handle.net/20.500.11984/14464 eng © 2025 IEEE IEEE
