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

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.
