Class Power Electronics

The aim of this course is to provide students with advanced scientific, technological, and technical knowledge in the field of Power Electronics. The theoretical component of the course is delivered in successive stages. The first stage provides students with the fundamental concepts concerning the static and dynamic behaviour of power electronic devices. The subsequent stages focus on developing students' ability to analyse power electronic circuits commonly used in energy conversion applications. These include AC/DC converters, DC/DC converters, DC/AC converters, and AC/AC converters, covering their various topologies, comparative analysis, and the advantages and disadvantages associated with each topology. During the course, fundamental electromagnetic principles of electrical machines are also introduced to facilitate the understanding of these types of loads, which are commonly supplied by power electronic converters.

Not applicable

Semiconductor devices commonly used in Power Electronics: static and dynamic operating characteristics; characterization and definition of the Safe Operating Area (SOA); di/dt and dv/dt protection. Static power converters. Transient phenomena in circuits employing diodes and thyristors. Uncontrolled diode rectifiers. Thyristor-controlled rectifiers. AC/AC converters Characteristics of the appropriate electronic switching devices. Analysis of the operating principles of AC/AC converters. Study of their application in real-world case studies. AC/DC converters The same analyses and case studies. DC/DC converters The same analyses and case studies. DC/AC converters The same analyses and case studies.

The course combines traditional lectures with learning activities designed to promote continuous learning. Laboratory sessions provide students with opportunities to apply the theoretical concepts through integrated practical assignments supported by simulation tools. Each laboratory assignment requires the submission of a preliminary report, which contributes to the continuous assessment. Continuous assessment consists of homework assignments, intermediate summative assessment, and laboratory assessment, in accordance with the ULP Assessment Regulations, and is calculated as follows: Final Grade = 0.45 × Final Examination + 0.45 × Laboratory Assignments + 0.10 × Participation/Attendance Students taking the resit examination will have their final grade calculated as: Final Grade = 1.00 × Final Exam
