The aim of the course is to provide basic understanding of the need for power electronics in modern society. The course provides students with basic understanding of power semiconductor devices, their operating principles and necessary control circuits and how they are used in different applications. Several important converter topologies for different applications such as power supply from the grid, voltage converters in an electronic system, motor drives, high voltage direct current transmission, etc., are described and analyzed. After completing the course the student possesses knowledge about various types of circuits in power electronics, its pros and cons and for what applications each circuit is used. The student can furthermore analyze the function of various power electronics applications and on a principal level construct a power electronics application.

Course objectives

After the course the student should be able to:
- Understand the importance of Power Electronics and its applications in modern day life
- Describe the modern power semiconductor devices such as Power Diodes, BJTs, MOSFETs, Thyristors, GTO, IGBT etc., their operation and control along with their protection schemes
- Calculate the power dissipation in the Power electronic component and design a cooling system.
- Understand the importance of magnetics (such as inductors, transformers) in power converter circuits.
- Dimensioning of magnetics for various applications.
- Select a suitable power converter topology depending on application
- Design a power converter for a given application
- Analyze the quality of the input/output waveforms in different converter circuits which are a major concern with respect to its surroundings
- Describe the basic principles behind HVDC systems and FACTS controllers


The course is an introduction to power electronics and covers the following areas
- Power semiconductor devices
- Gate/base drive circuits
- Review of electric and magnetic circuit concepts
- Heat dissipation in components and cooling
- Diode bridge rectifiers
- Line frequency phase controlled rectifiers along with Thyristor circuits and control
- Non-Isolated and Isolated DC/DC converters
- DC-AC converters (Inverters)
- Resonant (soft switching) converters
- Syncronous rectification
- HVDC (High Voltage Direct Current)
- FACTS (Flexible Alternating Current Transmission Systems)
