Electro-thermal simulation study of different core shape planar transformer

Using Finite Element Method this paper performs analysis over different type of magnetic core shapes from both electromagnetic and thermal perspectives. In this article,the planar transformer modeling and simulations intend to reveal the aspects that help the designer to choose between types of core shapes considering a more efficient use of copper, a better use of board space and an improved thermal dissipation. Using Solidworks application two planar transformer models have been developed taking into account both rectangular and a round centre post. For the FEM analysis 3F3 and 3F4 magnetic material properties were applied to models and the secondary top and bottom winding were used.
