Originální abstrakt

The paper explains basic ideas how to model dynamical properties of switched DC-DC regulators by means of so-called generalized transfer functions (GTFs). These functions were originally developed for modeling the real switched capacitor filters. However, they can be also used for modeling general linear systems with periodically varying parameters. Switched DC-DC converters like bust or bust-buck types exhibit some properties of continuous- and discrete-time characters. These systems can be globally modeled by mixed s-z description, utilizing both the Laplace and z-transform operators. Then the resulting line-to-output and control-to-output transfer functions and the corresponding frequency responses can model some system behavior more truly than the classical s-domain zeros/poles location, including special effects above the Nyquists frequency.
