What is Magnetic Core Effects on Transformers about?

This paper examines high-frequency transformer losses due to eddy currents in conductors and cores, presenting a detailed model that incorporates skin and proximity effects. It finds that while eddy current losses in the magnetic core increase winding resistance at low frequencies, their impact diminishes at high frequencies, making the impedance characteristics of windings with and without a magnetic core similar. The study utilizes analytical and finite element methods to validate these findings through s
