Abstract :
An efficient method for modeling the global magnetic properties of the transformer under dc-biased condition based on a laminated core model of product level is proposed. The magnetic property data of the core under dc-biased condition are obtained, such as the Bm-Hb curve and hysteresis loops, which can be used in the analysis of dc-biased field and electromagnetic design of products. The exciting currents of dc-biased laminated core model are calculated and validated with the measured ones.
