Learning activities and methodology
-Master classes, where will be the knowledge that students need to acquire. To facilitate its development students will receive the transparencies of class and will have basic texts of reference enabling them to complete and deepen the topics in which they are most interested. -Practical classes aimed at the resolution of exercises. These classes are complemented with the problem solving by the student who will serve as for self-assessing their knowledge and acquire the necessary capabilities. -Laboratory practice, where the student designs, assembles and test or simulate a power electronic system. These classes allow students to manage teams of electronic instrumentation, a commercial software for circuit simulation and the main electronic components that are object of study. -There will be sessions of group tutorials, focused on the questions of each of the educational units of the subject after the partial exams and before the final exam.
