Métodos de ensino e atividades de aprendizagem

The theoretical classes will have a component based on the exposition of the programmatic content of the curricular unit and another component based on the exemplification, in terms of applications and in solving problems. Each group of students will carry out a research work on one of the topics addressed in the curricular unit, which will be the subject of public presentation and discussion. In the laboratory part will be emphasized the test of photovoltaic systems, connected to the grid and isolated from the grid, with storage in batteries. The various types of electronic power converters used in a photovoltaic system will be tested and analyzed.
