A complete transformer electric model, including frequency and geometry effects

Abstract

An electric model for transformers, including both frequency and geometry effects, is presented. From Maxwell's equations an electric circuit which represents the transformer behavior is obtained. Expressions for calculating the circuit parameters from the winding layer geometry are given. The model's inclusion in simulation programs and its limitations are discussed. Experimental results showing the accuracy of the model are provided.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
