This paper presents an equivalent circuit of high frequency/high power planar transformers obtained using the Finite Element Method. The main transformer parameters: resistances, inductances and capacitances are computed considering different winding arrangements, evaluating and comparing their equivalent circuits and behaviors. In order to validate the proposed procedure that computes the planar transformer electrical parameters, a prototype has been realized. A real application is proposed and the numerical results are compared to the measured ones. The good agreement between them confirms the accuracy of the extracted equivalent circuit of the planar transformer.

Abstract

This paper presents an equivalent circuit of high frequency/high power planar transformers obtained using the Finite Element Method. The main transformer parameters: resistances, inductances and capacitances are computed considering different winding arrangements, evaluating and comparing their equivalent circuits and behaviors. In order to validate the proposed procedure that computes the planar transformer electrical parameters, a prototype has been realized. A real application is proposed and the numerical results are compared to the measured ones. The good agreement between them confirms the accuracy of the extracted equivalent circuit of the planar transformer.
