Abstract: Switched-Mode Power Supplies (SMPS) are the backbone of modern power electronics due to their efficiency, compactness, and versatility. This paper
presents an in-depth exploration of dynamic modeling techniques for SMPS, emphasizing mathematical formulations, linear and nonlinear system representations, state-space averaging, and frequency-domain analyses. The
goal is to provide researchers and practitioners with a comprehensive reference that covers theoretical foundations, practical modeling strategies, and simulation insights. Tables and figures are used to distill complex
concepts into digestible formats. The paper also discusses control strategies, stability considerations, and design optimization methods. Finally, future research directions and challenges in modeling modern SMPS topologies are
presented.

Keywords: Dynamic modeling, switched-mode power supplies, state-space averaging, small-signal analysis, control design, stability
