Module summary

The teaching and assessment methods shown below will be kept under review during 2020-21. In particular, if conditions allow for alternative formats of delivery, we may amend the timetable and schedule appropriate classes in addition to (or in place of) the Online Learning Workshops. For Semester 2 (from January 2021), we anticipate that this will be most likely, in which case online teaching will be substituted for traditional face-to-face teaching methods, including lectures and practical classes. ‘Independent online learning’ will involve watching pre-recorded lecture material or screen-casts, engaging in learning activities such as online worked examples or remote/virtual laboratory work, etc. Students will be expected to fully engage with all of these activities. The time commitment for independent online learning, and also the frequency and duration of Online Learning Workshops, are approximate and intended as a guide only. Further details will be confirmed when the module commences.


Power electronics is the technology involving controlled conversion of electrical power. It is used extensively in many applications ranging from mili-watts (those used in portable electronics) to giga-watts (those used in the power transmission through high DC voltages). Whilst power electronics continues to be the vital component for motor drives in automation/robotics and transportation, it is also a key enabling technology for power management in renewable energy systems, future electricity networks and energy storage systems. This module gives students an opportunity to appreciate how power electronics can play an important role in many engineering systems as well as to develop the knowledge and skills required by an engineer working in power electronics.

Objectives: This module gives students an opportunity to explore the applications of power electronics for machines and other conventional electrical systems. It provides students the skills in analysing, designing, simulating and evaluating power converters for the control of various applications.

Learning outcomes
On completion of this module students should be able to:

1. Comprehend the principles of a switch-mode power supply and its associated components; explain and analyse how isolated DC-DC converters are used in a switch-mode power supply.
2. Understand the structure of a DC drive system; analyse chopper controlled and thyristor controlled drives; explain qualitatively and quantitatively the dynamics of a variable speed drive for DC machines.
3. Develop full understanding on a three phase bridge converter and its control method.
4. Understand the structure of an AC drive system; apply a three phase bridge converter to control an AC machine under variable-frequency and variable-voltage operations.
5. Comprehend the principles of grid connected power electronics; develop understanding on the grid interfacing and control methods for various electrical systems.
6. Develop the skills in analysing various power electronics systems through simulation models implemented in contemporary computer software.


Topics may include, but are not limited to:

Switched-mode power supplies with transformer isolatio
DC machine drive
Three-phase DC-AC converter
AC machine drive
Power electronics for grid connected systems
