Modeling of a self-oscillating peak-current controlled flyback converter is presented. Transfer functions describing the output dynamics of a flyback converter are obtained by applying partial derivatives to the nonlinear state equations that are derived using proposed modeling method. Loop gain of a practical 3-W flyback converter was measured and compared to predictions. The time delay in boundary mode showed not significant influence on the converter dynamics in the load range of interest. The non-minimum phase characteristics of a flyback converter will limit the achievable controller bandwidth also in a variable-frequency operation similarly to the fixed-frequency operation in CICM and DICM.
