13. Output voltage and current tracking strategies of a voltage source converter. / Estudo de estratégias de rastreamento da corrente e da tensão de saída CA de um conversor do tipo fonte de tensão.
Este trabalho apresenta algumas estratégias de controle das malhas de rastreamento de tensão e corrente no lado CA de conversores do tipo fonte de tensão com filtro L ou LC. A topologia escolhida para o controle de tensão CA do inversor é a de duas malhas de controle em cascata: malha de tensão e malha de corrente, sendo esta última mais interna no si

14. Duble forward converter with two main and auxiliary switches and soft switching / Conversor duplo Forward PWM a duas chaves principais e duas chaves auxiliares com comutação suave
Converting a constant voltage in another constant voltage is necessary in many technological applications, starting from charging a cell phone battery to feed a DC motor in industrial plants. This work presents one more way to convert a Constant voltage based on a new circuit topology. This topology has its embryo in the simplest step-down configuration, the

16. CONTRIBUIÇÃO AO ESTUDO DA MÁQUINA ASSÍNCRONA TRIFÁSICA DUPLAMENTE ALIMENTADA APLICADA A AEROGERADORES DE VELOCIDADE VARIÁVEL
This work presents the analysis and implementation of a vector control applied to Doubly-Fed Induction Generators (DFIG) used in grid connected wind turbines. DFIGs are nowadays the more widely used concept for grid connected wind turbine, especially for rated power above 1 MW. The main reason is the low rotor PWM power converter rating. The present work dea

17. WIND TURBINE: MODELING, ANALYSIS AND CONTROL OF DOUBLY FED INDUCTION GENERADOR / TURBINAS EÓLICAS: MODELO, ANÁLISE, E CONTROLE DO GERADOR DE INDUÇÃO COM DUPLA ALIMENTAÇÃO
This thesis presents the main concepts and configurations used in wind turbine connected to the grid, as well as, an analysis, design and implementation of the control system for the Doubly Fed Induction Generator (DFIG). The DFIG has been selected since it is the concept frequently adopted by the wind turbine manufactures. In the thesis, it is presented a m
