Wind Energy Conversion Systems Based On a DFIG Controlled By Indirect Vector Using PWM And SVM

A well-prepared abstract enables the reader to identify the basic content of a document quickly and accurately,). This work presents consideration and use of the asynchronous generator in the production of wind energy. To do this, a model of the wind turbine has been established, the mathematical model of the doubly fed induction generator (DFIG) variable speed is presented and the control quantities used when integrated with a wind system. A modeling in a diphasic reference mark related to the stator field and a strategy vector control active and reactive power are offered with a PWM and SVM technique for inverter control is considered in our work

Performance Analysis of the Multi-Level Boost Converter (MLBC) connected in a Photovoltaic System

The paper concentrates on a comparison between two DC/DC converters topologies, the conventional Boost and the Multi Level Boost Converter (MLBC), for connecting into PV systems. Several performance criteria are included as part of this comparison process for both converters under varying climatic conditions (irradiation and/or temperature). The DC/DC converters' function is to serve as an interface between PV generator and load. We apply MPPT (Maximum Power Point Tracking) control with duty cycle adjustment using PWM technique for extracting the highest achievable output power from PV generator. The multilevel boost converter (MLBC), which is capable of monitoring and maintaining an equal voltage on all N output levels, along with controlling the input current. MATLAB/Simulink simulation results highlight the performance of the Multi-Level Boost Converter (MLBC) converter topology, to match the GPV voltage to the load
