Abstract

A simplified capacitive model for transformers with center-tapped windings has been developed. A Finite Element Analysis (FEA) tool is used to compute the electric energy in the windings of the transformer in order to obtain the required parameters of the model. Due to its reduced number of elements it can be easily used to model the capacitive effects in symmetrical (center-tapped) multi-winding magnetic components such as transformers for Push-Pull (PP), Half-Bridge (HB) and Full-Bridge (FB) applications. Some experimental results are compared with simulations.
