Forms of Teaching
Lectures are organized through 2 teaching cycles. The first cycle consists of 7 weeks of classes and mid-term exam, a second cycle of 6 weeks of classes and final exam. Classes are conducted through a total of 15 weeks with a weekly load of 3 hours.Exams
Examination consists of mid-term exam and final exam in which numerical problems are solved, and the writing of reports on laboratory exercises.Exercises
On the oral exercises the process of solving complex medium and complex problems is shown to students.Laboratory Work
Laboratory exercises are organized in 3 cycles of thematically linked to the 3 main areas of the lectures (electrical machinery, electronic power converters, motor drives).
