Abstract An efficient method for modeling the global magnetic properties of the transformer under dc-biased condition based on a laminated core model (LCM) of product level is proposed. However, the dc bias magnetic flux can not be measured directly in the experiment, and then a simulated method is proposed to calculate the dc magnetic flux in the iron core. The calculation program is developed based on the commercial software Matlab, thus the hysteresis loops of the iron core under biasing magnetization are obtained. Experimental study on the iron loss of the transformer is carried out, the different iron loss curves under various dc-biased magnetic field strength are determined. They are necessary for the analysis of dc bias magnetic field and electromagnetic design of products.

Key words： DC biasing power transformer laminated core model DC magnetic flux hysteresis loops iron loss curves
