Core loss behavior in high frequency high power transformers—I: Effect of core topology
TL;DR: In this paper, an overview of core loss computations performed in both time and frequency domains in order to evaluate their behavior in single phase transformers with different core topologies is presented, and the effects of non-sinusoidal waveforms on well-known core loss calculation methods are investigated with both analytically and finite element calculations.

Modification of empirical core loss calculation methods including flux distribution
E. Agheb,Hans Kristian Hoidalen +1 more
TL;DR: In this article, the spatial distribution of flux density inside the core was investigated and it was shown that non-even distribution of the flux results in higher maximum temperature of the core.
