Course Description

The aim of the course is to give the student knowledge of principles for power electronics such as voltage conversion and power control. After completed course shall the student know how to:

  • explain and analyze the function of DC-DC, AC-DC and DC-AC converters

  • calculate the waveforms in DC-DC, AC-DC. and DC-AC converters

  • describe the function of common semiconductors used in power control

  • describe and model thermal effects

  • describe various pulse width modulation principles

  • describe the control of DC-DC, AC-DC and DC-AC converters

  • know about drive and protection circuits for power control

  • define the base requirements for selection of components in converter design

Course setup

The course is given through lectures where theory and exercises are mixed. Three labs are given for practice through computer simulation and also through operation and measurement using real circuits.


Course content

Power electronic application overview (switch-mode power supply, variable speed drive, high voltage applications (HVDC, SVC)), diode rectifiers, thyristor rectifiers, switch mode converters (DC-DC, AC-DC and DC-AC), power semiconductors, semiconductor rating and thermal effects, converter control and protection

Laborations

The laboratory work consists of two computer lab sessions and one measurement lab session, where each session is 4 hours. One additional lab session is offered as an option to complete any of the computer or measurement labs. The laboratory work is carried out in groups of one or preferably two students each.

The tool to use for computer labs is Multisim, which is also available from the student portal (in the National Instruments package). A short introduction to Multisim and the laboration is now available here (57k pdf).

The measurement lab will be done using the National Instrument ELVIS platform and Labview control software.
