Stratégie de pré-dimensionnement de convertisseurs statiques : Application à une alimentation 42V-14V réversible pour l'automobile.

Abstract : This thesis deals with a new design methodology for power converters. It is based on the development of simple analytical models on which the compromise precision-speed was imposed. An analysis of the different methods of modelling was carried out for the various physical phenomena in presence (Electromagnetic Compatibility EMC, ripple, dynamics, thermal limitations, volume.). A synchronous rectifier dedicated to automotive has been used to carry out a validation of this methodology. Several optimization strategies have been investigated, as well as their influence on the used models. This new methodology allows to find a viable technological solution but also permits to look back and improve the specifications.
