     Based on the method of “High Frequency Network Averaging”,an unified approach to modeling DC DC PWM converters in discontinuous inductor current mode operation is proposed. Low frequency behavior models are derived. These models,on the one hand,serve as a basis to derive differential equations of the converters,on the other hand,are very suitable for SPICE simulation,where DC and small signal characteristics can be easily obtained.

High Frequency Network Averaging(HFNA),in which the elements whose currents(or voltages) vary very fast are replaced by dependent sources controlled by low-frequency variables,is presented in this paper.A nonlinear invariant equivalent circuit of Quasi Resonant Converter(QRC) is obtained.This new approach and its resulting models are circuit-oriented and helpful to the analysis and design of QRC.
