Accurately estimating the core power losses under the trapezoidal induction waveform, and analyzing its variation with the duty cycle, are essential for the elaborate design of high-frequency transformers used in dual-active-bridge (DAB) dc-dc converters. In this paper, core power losses under trapezoidal induction waveform are theoretically predicted by considering the specific role of hysteresis,...
The effect of the variation of B-H properties obtained by different means and data access modes on iron loss and flux in grain oriented (GO) silicon steel laminations is investigated under different exciting frequencies in order to determine an efficient numerical approach to model the lamination configurations. The computational and experimental results are demonstrated on benchmark models in which...
