EJ2300 Power Electronics 7.5 credits

Effektelektronik

Electricity plays a vital role in supplying energy to computers, electronics, industrial processes, trains and many other applications. They all have in common that the electrical energy has to be converted and controlled in a precise manner.
This course provides in depth knowledge of power converter topologies, their characteristics and principles for their control. The course also covers the basics of modern power semiconductors.

Electricity plays a vital role in supplying energy to computers, electronics, industrial processes, trains and many other applications. They all have in common that the electrical energy has to be converted and controlled in a precise manner. This course provides in depth knowledge of power converter topologies, their characteristics and principles for their control. The course also covers the basics of modern power semiconductors.

Intended learning outcomes *

Aim of the course is to give the students tools to be able to analyse and understand the main circuits that are used for power electronic converters.
After completed course the student should be able to

  • describe the operating principle for a general power converter by using the basic equations for an inductor and capacitor.
  • calculate important measures like average value of output voltage and fundamental content of line current.
  • explain different operating conditions.
  • outline the control of power converters.
  • describe modern power semiconductors, their control and protection.
  • dimension and analyze a simple converter both electrically and thermally.
