Abstract
An approach of High Frequency Network Averaging (HFNA) is presented for analysis of Quasi Resonant Converters (QRC´s). The elements whose currents (or terminal voltages) vary very fast are replaced by dependent sources controlled by low-frequency variables and nonlinear structure-invariant equivalent circuits of QRC´s can be obtained. This new approach and its resulting models are circuit-oriented and helpful to the analysis and design of QRC´s
