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.
