Subject description

Prerequisits:

  • Formal condition: enrolment in the study year.
  • Lectures, laboratory excercises with previous study. Due to high voltage and currents the laboratory work must be carried out in small groups of students.
  • Students must succesfully finish all of their laboratory duties before they can apply for an exam.

Content (Syllabus outline):

  • Overview of power electronics main topics. A brief historical development of electrical switches. Semiconductor switches: physical principle, conventional and modern switches, static and dynamic characteristics, important parameters, selection, dimensioning, protection, cooling, future trends.
  • Uncontrolled rectifiers: operation, commutation, characteristics, dimensioning.
  • Controlled rectifiers: operation, commutation, characteristics, dimensioning, load influence. Control demands, design of control pulse devices.
  • Influence of controlled rectifiers on supply grid, phase shift, reactive power. Principles of reactive power reduction.
  • Inverter topologies, converters in ac and dc circuits. Principles of modulations, pulse width modulation, Voltage and current source inverters, characteristics, basic topologies. Applications of semiconductor converters in electrical drives, typical examples from the industry.
  • Transient loses, inductors and capacitors. Influence of converters on the grid, pasive and active filters, EMC compatibility and protection.

Objectives and competences:

To acquire knowledge on elements and devices of power electronics which are applied in controlled electrical drives, to understand their operation, to select and optimize them and include them in complex automated systems.

Intended learning outcomes:

Students will learn about components of power electronics circuits and their priciples of operation. They will be awared of importance to realize high efficiency at energy conversion from the technical, economical and ecological point of view.

Learning and teaching methods:

  • Lectures,
  • laboratory work with prior demonstration and computational excercises.
