Abstract
We demonstrate the need for treating switching converters as discontinuous systems in order to properly analyze their dynamics and stability. We also outline some concepts related to the stability analysis of these variable-structure systems. Using these concepts, we investigate the stability and dynamics of a stand alone and an integrated DC-DC buck converter, which represents a nonlinear dynamical system under closed-loop operation. We compare the results with some of the existing ones, which are based on small-signal analyses, and demonstrate the shortcomings of the latter.
