POWER ELECTRONICS - 2019/0

Module Overview

Expected prior learning: Modules EEE2033 – Electronics III: Circuits, Control and Communications (5-elC), and EEE2038 – Electronics IV: Electronics and Power Systems (5-epw), 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 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 written examination will assess the analytical and problem solving skills, background understanding of electrical power systems and power conversion techniques and extend of transferable and professional skills that are relevant to the power industry.

 

Thus, the summative assessment for this module consists of a 2-hour, closed-book written examination.

 

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

          ·         Via peer assessed in-class quiz and discussions on AC to DC, DC to AC and DC to DC converters in week 10.

 

Module aims

• This module aims to build on the concepts of power electronics by introducing power electronic switching devices and 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 Week 10.
  


• 
  Prepare for summative assessment through intensive in-class revision in Week 11.
  


• 
  Lecture notes will be provided and students are expected to do independent learning in addition to attending lectures and tutorials.
  

• 
  3 hours lecture per week x 10 weeks which includes class discussion and problem solving sessions.
  


• 
  3 hours in-class revision in Week 11.
  

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.
