Chair of Power Electronics

Design of Power Electronics Converters


Prof. Dr.-Ing. Marco Liserre and staff

Target group:

Students of the master courses “Electrical and Information Engineering” and “Electrical and Information Engineering and Business Management”

Recommended prerequisites:

Introduction to electrical energy technology, Power Electronics I


4 SWS (3 SWS lecture, 1 SWS exercise), 6 ECTS
English (lecture), English/German (exercises)


The course is a basic course for developing a career in power electronics. The current drivers in power electronics design are efficiency, reliability and cost. For this reason the course will guide the students in selecting the different components of the power electronics converters with attention paid to efficiency and reliability and as a consequence to the management of the temperature.
The impact of PWM on these subjects will be highlighted together with the more classical study of harmonic behavior and linearity.

Topics overview:

  • Design of a Power Electronics Converter (Semiconductors and Drivers, Soft and hard switching, passive components, Busbar design, EMC problems and remedies, Thermal model)
  • Topologies of PWM power converters (dc/dc, dc/ac, ac/ac): single-cell and multi-cell converters, matrix converters etc
  • PWM modulation (single-phase, three-phase, space-vector, multilevel, interleaving, continuous/discontinuous, optimized)
