Subject Overview:


The aim of this subject is to understand the fundamental concepts and basic theory involved in modelling and analysis of the power electronic components that comprise power electronic devices such as power supplies, inverters, converters and their control systems. It is expected that at the end of this subject the student has a sound understanding of the physical concepts and mathematical models behind each of the basic components and of their functionality within a system, such as a high voltage DC transmission system. Furthermore this subject seeks to combine the fields of electronics, semiconductor devices, power system operation, power system measurement and control. It is expected that through this subject the students are exposed to examples of real electrical engineering systems where the three disciplines of electronics, power systems and control come together.


Topics covered in this subject include: introduction to power semiconductor switches; discussion on the role of power electronics in the operation of electric power systems; models of power semiconductor devices and circuit components, including diodes, Thyristors, IGBT, Snubber circuits. Also basic concepts of single- and three-phase diode bridge rectifiers; single- and three-phase converters and inverters; operation and design of DC-AC inverters with emphases on switch-mode inverters, i.e. single- and three-phase inverters. Finally, the acquired knowledge of power electronic devices is applied to wind and PV solar systems where the design of voltage source converters and associated control loops are used to interface the wind/solar system with the power grid.

Learning Outcomes:


It is expected that on completing this subject the students should be able to:

  1. Apply physical principles, fundamental abstractions and modelling techniques in the analysis of power electronic components and devices
  2. Develop and demonstrate basic electrical engineering laboratory skills through simulation of practical real life electrical electronics devices and systems using software tools and analyse the performance and characteristics of each of its components
  3. Compare the performance of physical power systems obtained through simulation with theoretical analysis.

  • Continuous assessment of laboratory workshop outcomes in small groups (2-3 students) in weeks 2-12, requiring approximately 25-30 hours of work per student (20%)
  • One 90-minute mid-semester test held in week 6 or 7 (20%)
  • One written examination, not exceeding three hours, held during the end of semester examination period (60%).

Hurdle requirement: Students must pass the end of semester written exam to pass the subject.

Intended Learning Outcomes (ILOs) 1 - 3 are assessed in the final written examination, the mid-semester examination, and assignments. ILOs 2-3 are assessed as part of the laboratory workshops outcomes and written reports.

Prescribed Texts: None
Breadth Options:

This subject is not available as a breadth subject.

Fees Information: Subject EFTSL, Level, Discipline & Census Date
Generic Skills:

On successful completion of this subject, students will have developed the following skills:

  • Ability to apply basic fundamentals of science and engineering to solve real life problems associated with power systems
  • Ability for in-depth technical competence in power systems engineering discipline
  • Ability to identify, formulate, analyse and solve practical engineering problems
  • Capacity for independent critical thought, rational assessment and self-directed learning
  • Ability to communicate and work effectively with teams
  • Ability to write technical reports in a clear and concise manner
  • Ability to present results of technical investigation to a large audience.


This mode of delivery of this subject is through lectures supported by tutorial s and practical hands-on workshops.


Full set of lecture notes, tutorial sets and model solutions as well as workshops reports are provided.


Guest speakers from power industry are usually invited to give seminars on technical issues related to their respective companies and how these issues relate to the content of this subject.
