Class Power Electronics

With this course students are expected to acquire scientific, technological and technical knowledge of advanced-level power electronics. Theoretical lecture develops in phases. In the first one, basic knowledge about the static and dynamic behavior of several power electronic components is conferred . The following phases are aimed at developing the capacity to analyze power electronic circuits normally used in energy conversion, namely, AC/DC converters, DC/DC converters, DC/AC converters, AC/AC converters, in their various topologies, comparison between them, as well as the analysis of the advantages and disadvantages associated with each topology. During the study, some electromagnetic principles of electrical machines will be introduced in order to better understand these types of loads normally applied to converters.
