This paper focuses on proximity losses prediction in conductors of power electronics transformers. The method is based on the concept of equivalent complex permeability applied to rectangular conductors. A 1-D analytical model is analyzed. It has been shown that the 1-D model does not take into account edge effects. Two complementary approaches have been proposed. One treats scattered conductors; other deals with package of conductors. Both approaches are compared with a good accuracy and economic computation time
