Module summary

The teaching and assessment methods shown below will be kept under review during 2021-22. 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) any online activities/sessions. Where learning activities are scheduled to take place on campus, it may be possible and/or necessary for some students to join these sessions remotely. Some of the listed contact hours may also be optional surgeries. Students will be provided with full information about the arrangements for all of these activities by the module staff at the beginning of the teaching semester.‘Independent online learning’ may involve watching pre-recorded lecture material or screen-casts, engaging in learning activities such as online worked examples or mini-projects, 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 sessions are approximate and intended as a guide only. Further details will be confirmed when the module commences.Where assessments are shown as Online Time-Limited Assessments, the durations shown are indicative only. The actual time permitted for individual assessments will be confirmed prior to the assessments taking place.

Objectives

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. Discuss the principles of a switched-mode power supply and its associated components.
2. Perform circuit analysis and calculations for isolated DC-DC converters used in a switched-mode power supply.
3. Explain, qualitatively and quantitatively, the structure of a DC drive system including the use of chopper-controlled and thyristor-controlled drives, and the dynamics of a variable speed drive for DC machines.
4. Use a simulation model to analyse a DC drive system.
5. Explain the structure of an induction machine drive system under variable-frequency and variable-voltage operations.
6. Use mathematical and simulation models to investigate induction machines under variable-frequency and variable-voltage operations.
7. Analyse the power flow, interfacing, and control methods for grid-connected inverters.
8. Use a simulation model to analyse a grid-connected inverter.

Private study

Students are expected to use private study time to consolidate their understanding of course materials, to undertake preparatory work for seminars, workshops, tutorials, examples classes and practical classes, and also to prepare for in-course and summative assessments.


Opportunities for Formative Feedback

Students studying ELEC modules will receive formative feedback in a variety of ways, including the use of self-test quizzes on Minerva, practice questions/worked examples and (where appropriate) through verbal interaction with teaching staff and/or post-graduate demonstrators.
