Learning Outcomes
Having completed the course, the student recognises the applications of semiconductive components used in converter use and their use as part of modern converter connection. The student has basic knowledge on converter applications of controlled electric drives, such as the grid-connected rectifiers and inverters of a frequency converter in power production. The student has skills to dimension a converter for various loading conditions and recognises the network effects of converters, such as the mechanisms of the generation of current harmonics and reactive power.
Student's Workload
135 hours, of which in addition to lectures, 4 x4x hours for laboratory assignments, 2 hours for the exam.
Prerequisites / Recommended Optional Courses
