Mechanism Investigation and Analytical Modeling for Winding Loss of Flyback Transformer

摘要

Modeling and analysis for winding loss of Flyback transformer is a focus. Although there are many literatures[1-6] on the work, some disreputations still exist. In this paper, Flyback transformer winding loss mechanism was deeply analyzed by winding current decomposition and magnetic motive force (MMF) analysis firstly. Then a novel analytical winding loss model is proposed.
