Mechanism Investigation and Analytical Modeling for Winding Loss of Flyback Transformer

Modeling and analysis for winding loss of flyback transformer is a focus. Although there are many literatures 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. Mechanism analysis for winding loss of flyback transformer.
