Short Description

This is an advanced course in power electronics, providing insight into the devices, circuits and software used to control electric motors and generators. Students are prepared to design such systems, along with their cooling techniques, and associated dc-dc convertors and power converters for various applications.

Main Assessment In: December

Are reassessment opportunities available for all summative assessments? Not applicable

Reassessments are normally available for all courses, except those which contribute to the Honours classification. For non Honours courses, students are offered reassessment in all or any of the components of assessment if the satisfactory (threshold) grade for the overall course is not achieved at the first attempt. This is normally grade D3 for undergraduate students and grade C3 for postgraduate students. Exceptionally it may not be possible to offer reassessment of some coursework items, in which case the mark achieved at the first attempt will be counted towards the final course grade. Any such exceptions for this course are described below. 

Course Aims

This aims of this course are to:

■ provide students with an appreciation of the range of power electronic devices and circuits in modern, practical, high power electrical systems;

■ develop a solid understanding of the operation of electronic control systems in high power electronics;

■ prepare students to design such systems.

Intended Learning Outcomes of Course

By the end of this course students will be able to:

■ design and construct dc-dc converters with power ratings of ~10-100 W;

■ evaluate the performance and efficiency of a range of advanced dc-dc converter designs;

■ explain how to exploit the behaviour of dc-dc convertors for maximum power point tracking;

■ identify different thermal management techniques in current industrial use;

■ assess the performance of cooling systems in steady state;

■ predict the thermal behaviour of power systems during transient events;

■ list common power amplifier classifications;

■ assess high power linear amplifier suitability with reference to specified load characteristics;

■ contrast the performance and efficiency of power amplifiers using differing topologies;

■ identify motor drive topologies for a range of practical motors-including brushless dc, permanent magnet ac (embracing vector control), and induction machines;

■ analyse and design optimal drive systems for a range of applications, selecting the appropriate motor type;

■ critique different motor types and control options for fan, pump and actuator purposes;

■ illustrate the benefits of various generator topologies-including permanent magnet generators and induction generators (embracing doubly-fed induction generators);

■ contrast convertor topologies in terms of power quality, cost and efficiency;

■ select and integrate drive convertor components for a given turbine specification and electrical load;

Minimum Requirement for Award of Credits

Students must attend the degree examination and submit at least 75% by weight of the other components of

the course's summative assessment.

Students must attend the timetabled laboratory classes.

Note that these are minimum requirements: good students will achieve far higher participation/submission

rates. Any student who misses an assessment or a significant number of classes because of illness or

other good cause should report this by completing a MyCampus absence report.
