Robustness Analysis of DC Distributed Power Systems by Means of Behavioral DC-DC Converter Models

Inhalt:
The aim of this paper is to determine the model requirements for dc-dc converters in order to analyze and evaluate the performance of different architectures of DC distributed power systems and to assure that all the specifications are met under all parameter variations. Based on these requirements a parametric model for the dc-dc converters is presented that can be identified as a function of the information given by the manufacturers in their datasheets. In this way, it is possible to make sensitivity and worst case analysis that can help the designer to evaluate the robustness of their architectures.
