Abstract :
A small signal model for average current mode control based on describing function method is proposed. Modeling of average current mode control is more complicated than peak current mode control due to the additional current compensator. In this paper, two commonly used current compensators are considered as examples. The structure of average current mode control is compared with V2 control to find the similarity. Previous modeling result about V2 control is borrowed and modified for average current mode control. The proposed small signal model can be accurate up to switching frequency. The proposed model is verified using Simplis simulation and measurement.
