Augmented models of High-Frequency Transformers for SMPS [PDF]
2009 20th International Zurich Symposium on Electromagnetic Compatibility, 2009 The modeling of high-frequency transformers via augmented equivalent circuits is addressed. The augmented models are composed of a low-frequency equivalent and a supplemental element modeled via real rational fitting. They offer both high accuracy levels and a physical meaning that helps the interpretation of simulation results.

Winding Considerations on the High Frequency Transformers [PDF]
Energy Procedia, 2011 AbstractHigh frequency transformers, used in switching power supplies, carry high amount of current. High frequency effects like skin, proximity and edge effects are discussed in this paper. Multi stranded or litz wires are used for reducing skin effect, but it will be shown that they are not effective in transformer normal winding.

High frequency model of transformer winding
Electrical Engineering in Japan, 2003 AbstractA high frequency model of transformer winding is used to analyze the voltage oscillations due to various excitations such as the very fast transient overvoltage which occurs at the time of disconnecting switch operations. Usually, a circuit of interlinked inductances and capacitances is used for this purpose, in which circuit parameters have to
