Decoupled control scheme of grid-connected split-source inverters
2017
Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…
Vers un environnement informatisé d'évaluation de la qualité ergonomique d'interfaces multimédia : Étude exploratoire
2000
Our objective is to encourage the human-computer interface designers to be more interested in the uses made of their product by taking into account to a higher degree the human-factor in the testing phase which often is too focused on technical aspects. We want to facilitate the integration of the user as a source of evaluation during the testing phase. Our aim is to offer the designer a software environment of practical tests that allow them to have their own products evaluated by their users. We undertook an experiment to explore the feasibility of this project.
