A closed-form formula for 2-D ohmic losses calculation in SMPS transformer foils.

A closed-form formula for 2-D ohmic losses calculation in SMPS transformer foils.

A new formula aimed at calculating ohmic losses in switch-mode power supply (SMPS) transformers is presented. It is based on intensive two-dimensional (2-D) finite element method (FEM) simulations, the results of which have been summarized in a closed-form formula following a ?semi-empirical? approa...
