Title
Analysis and Design of Switched-Mode Power Converters Using Discrete Time Modeling
Abstract
Discrete time modeling of power electronics is a useful tool for small signal modeling and control design without requiring spectrum-limiting approximations. These same techniques are useful for the large signal, steady-state modeling and design optimization of power electronics. The modeling approach is general, accurate, and well-suited to numerical design optimization. This tutorial will review state space discrete time modeling of switching power converters with applications to steady-state and dynamic modeling and design optimization, ongoing efforts and resources being developed at the University of Tennessee, as well as application examples.
