| Abstract |
This work takes place within the frame of converters global operation study, study made thanks to SCRIPT software which is particularly well adapted to simulate electrical networks using switching semiconductor devices. Since interpretation of some physical phenomena requires a detailed analysis of local components comportments, the authors have to use circuit models that represent these elements more and more accurately. The models are adapted from similar studies established for the SPICE simulator which is based upon numerical semiconductor device modelling, thanks to direct solution of fundamental equations governing device behaviour. This paper aims to describe some semiconductor models, their hierarchy (Macro-Component notion) and their uses. This study offers the opportunity (and originality) of creating a close connection between two widely separated scientific fields: on the one hand, the physics of semiconductor device, on the other hand, the study of this same component from an electrical point of view. |
