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
This module develops the appropriate analytical skills and knowledge to design electrical power converters nd an understanding of power electronic conversion techniques, including the basic converters (DC-DC, AC-DC and DC-AC). Students will learn the methods of circuit analysis applicable to switched mode circuits, and gain familiarity with the properties of the relevant semiconductor devices.This module also covers the fundamental principles of three-phase circuits and connections, voltage and current analysis and real and reactive power calculations.Learning outcomes
On completion of this module students should be able to:
1. Explain the principles of power control by switching, recognise the typical semiconductor devices used in switching circuits and discuss the benefits of switched-mode circuits.
2. Perform circuit analysis and calculations, and select suitable components, for a range of standard DC-DC converter circuits.
3. Use phasor analysis to solve standard AC power circuit problems and use instantaneous power theory to define real, reactive and apparent power.
4. Perform circuit analysis and calculations for a range of thyristor-based rectifiers and quantify the current harmonics and the average power drawn by a rectifier.
5. Perform circuit analysis and calculations for H-bridge inverters and use phasor analysis to calculate the power delivered and absorbed by grid-connected inverters.
Syllabus
Topics may include, but are not limited to:
Characteristics of power devices
DC-DC converters
AC Current, Voltage and Power
Effects of power electronics on AC power
Rectifiers (AC-DC converters)

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.Methods of assessment
