POWER ELECTRONICS - 2022/3

Module Overview

Expected prior learning: Modules EEE2033 – Circuits, Control and Communications, or equivalent learning. Knowledge of linear systems and of the basics of control engineering is particularly helpful.

Module purpose: This module aims to develop a better understanding of transistor amplifiers, power semiconductor switching devices and various power converters. A detailed analysis of power converters like AC to DC phase controlled rectifiers, AC to AC, DC to DC converter & Pulse Width Modulated (PWM) inverters will be provided. In order to develop a broader understanding of this subject, a few domestic & industrial applications will be taught in this module.

Assessment pattern

Alternative Assessment

Not applicable: students failing a unit of assessment resit the assessment in its original format.

Assessment Strategy

The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes. The examination will assess the analytical and problem solving skills, background understanding of amplifiers, electrical power systems and power conversion techniques and extend of transferable and professional skills that are relevant to the power industry.

 

Formative assessment and feedback

Students will receive formative assessment/feedback in the following ways:

·         During lectures, by question and answer sessions

·         During tutorials/Problem based learning sessions
 

Summative assessment 

Summative assessment will consist of:

·         A 4-hour open-book examination submitted online

Module aims

• The module introduces analogue electronic device operation, including transistor amplifiers and power electronic switching devices. It covers power conversion techniques for various domestic and industrial applications.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to achieve the following aims.

• 
  Learning through regular lectures from Week 1 to 10. These lectures will include the problem solving sessions and in-class discussions.
  


• 
  Peer discussion and feedback session after formative assessment in latter weeks.
  


• 
  Prepare for summative assessment through intensive in-class revision during revision week.
  


• 
  Lecture notes and pre-recorded material will be provided, and students are expected to do independent learning in addition to ane ahead of attending lectures and tutorials.
  

• 
  2 hours lecture+tutorial in-person sessions per week x 10 weeks which includes class discussion and problem solving sessions.
  


• 
  2 hours in-class revision in revision week.
  

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
