Abstract :
This paper presents a model of large air gap transformer composed of two E cores. Approach is based on the magnetic equivalent circuit using reluctance network and considers two and three dimensions phenomena. Thanks to this analytic model, it is possible to determine rapidly and easily electrical parameters of a two windings transformer in order to design such magnetic devices. Finally, 2D and 3D finite elements method are used to demonstrate the accuracy of this model.
