Design and modeling of integrated octagonal shape inductor with substrate silicon in a buck converter

The paper discusses the design and modeling of an integrate octagonal shaped inductor with silicon substrate. A validated equivalent electrical model of the integrated octagonal shaped spiral inductor is developed. The model is used to analyze and evaluate the quality factor and the inductance of the inductor structure proposed under different physical parameters setting. These include the number of turns, spacing between turns and the inner diameter. The simulation results show that an appropriate selection of physic a parameters can achieve an enhanced quality factor and improved inductance. PSIM simulator is used for the implementation of the integrated inductor in a micro buck converter. The simulation results demonstrate that our proposals are very promising approaches for the monolithic integration of DC-DC converters

Modeling and Control of multimachines System Using Fuzzy Logic

International audiencehis work is devoted to modeling and vector control by fuzzy logic of a multimachines system connected in series. A six-phase asynchronous machine connected in series with a three-phase asynchronous machine fed by a single inverter and controlled independently. Thanks to the powerful means of calculation, which made possible the control of such a system and this allows its integration in applications where the constraints of space and weight require a particular attentio

An improved INC-MPPT algorithm based on passivity approach for photovoltaic system

International audienceNew robust algorithm of Maximum Power Point Tracking (MPPT) for an extraction system solar energy by photovoltaic effect is tackled in this paper. Indeed, the algorithms available today, suffer from non-robustness against climate change as well as system settings. This requires a deep study of the simulation of a robust controller system. Therefore, it is proposed, the Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) application for maximum power point tracking (MPPT), which shows its efficiency and robustness compared to other methods (such as Incremental Conduction), as fast and the decrease against climate perturbations and variationsof system parameters
