Power electronics systems deal with the process of converting electrical power from one form to another. The syllabus reflects the learning objectives of curricular unit.The main learning objective of this curricular unit is to provide students with technical knowledge about energy conversion based on power electronics converters, including an understanding of the main conversion topologies, their operating principle and their applications, as well as of design and control. Students should acquire the necessary skills to simulate and study the classical converters under analysis, as well as be able to implement the same converters in a laboratory environment. With the knowledge provided in this curricular unit, the students will be able to have an integrated view of power generation and conversion systems, particularly from the power electronics point of view.
