Discrete-time modeling tools for DC-DC converters

Abstract

The objective of the discrete-time modeling tools is twofold. First, they give an insight into the basic ideas of discrete-time modeling of dc-dc converters for university students and interested power electronics specialists. Second, as it is being presented below, the interactive calculation tools facilitate the fast and simple modeldevelopment in WEB browser after entering the basic circuit and load parameters. This feature can especially be useful for the practicing design engineers, since without long calculations with matrix functions the linearized discrete-time system model is immediately and automatically developed in both mathematical form (state-space equations and transfer functions in the Z domain) and also in graphical form (pole-zero map and bode plot).
