Aim

The aim of the course is to provide the basic knowledge for the requirement of Power Electronics in the modern day life. In this regard, the course aims to equip the student with the basic understanding of the power semiconductor devices, their operating principles along with their control circuitry together with the review of electric and magnetic circuits. Several important converter topologies applicable for various low - high power applications such as the switch mode power supplies (SMPS) with hand held devices, computers and high voltage DC transmission, PV systems, power supplies for telecommunication equipment etc., will be covered with detailed analysis. With this course, the student will be equipped with the knowledge in the wide range of power electronic converter circuits for AC-DC, DC-DC and DC-AC power conversion which are generally employed in various consumer and industrial electronic applications.

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
- Understand and analyze the quality of the input/output waveforms in different converter circuits which are a major concern with respect to its surroundings
