Description

This unit explores energy conversion, switching converter concepts, dc-dc converters, rectifiers, inverters, PWM (Pulse Width Modulation) and modulation strategies, ac-ac converters. General issues in power electronics such as discontinuous mode of operation, real sources and loads, power semiconductors and interfacing, magnetics fundamentals and control issues are also investigated.

Prerequisite Rule

For Honours level students only, must pass ENS1253

Equivalent Rule

Unit was previously coded ENS4205

Learning Outcomes

On completion of this unit students should be able to:

  1. Analyse the performance of power switching components and their application in power converters.
  2. Apply knowledge of power electronics to the sustainable design and development of electronic systems.
  3. Formulate designs for simple power electronic systems including dc-dc, single and poly-phase ac-dc, dc-ac and ac-ac converters.
  4. Analyse and verify designs for power electronic systems using appropriate software tools.

Unit Content

  1. Feedback control in converters.
  2. Power semiconductors in converters: diodes, thyristors, power-FET, power bipolar transistors.
  3. Concepts of magnetics for power electronics: transformer and inductor design.
  4. Real sources and loads, resistors and capacitors.
  5. Converters in discontinuous modes.
  6. Inverters and Pulse Width Modulation and ac-ac conversion.
  7. Diode-capacitor circuits and rectifiers.
  8. Dc-dc converters: buck, boost, flyback, buck-boost and boost-buck converters.
  9. Switching converter concepts, switch matrix, Fourier analysis, regulation, distortion.
  10. Energy conversion, efficiency and reliability objectives.

Learning Experience

Students will attend on campus classes as well as engage in learning activities through ECU's LMS

Assessment

GS1 GRADING SCHEMA 1 Used for standard coursework units

Students please note: The marks and grades received by students on assessments may be subject to further moderation. All marks and grades are to be considered provisional until endorsed by the relevant School Progression Panel.

Due to the professional competency skill development associated with this Unit, student attendance/participation within listed in-class activities and/or online activities including discussion boards is compulsory. Students failing to meet participation standards as outlined in the unit information may be awarded an I Grade (Fail - incomplete). Students who are unable to meet this requirement for medical or other reasons must seek the approval of the unit coordinator.

Disability Standards for Education (Commonwealth 2005)

For the purposes of considering a request for Reasonable Adjustments under the Disability Standards for Education (Commonwealth 2005), inherent requirements for this subject are articulated in the Unit Description, Learning Outcomes and Assessment Requirements of this entry. The University is dedicated to provide support to those with special requirements. Further details on the support for students with disabilities or medical conditions can be found at the Access and Inclusion website.

Assessment

Students please note: The marks and grades received by students on assessments may be subject to further moderation. Informal vivas may be conducted as part of an assessment task, where staff require further information to confirm the learning outcomes have been met. All marks and grades are to be considered provisional until endorsed by the relevant School Progression Panel.

Academic Integrity

Integrity is a core value at Edith Cowan University, and it is expected that ECU students complete their assessment tasks honestly and with acknowledgement of other people's work as well as any generative artificial intelligence tools that may have been used. This means that assessment tasks must be completed individually (unless it is an authorised group assessment task) and any sources used must be referenced.

Breaches of academic integrity can include:

Plagiarism

Copying the words, ideas or creative works of other people or generative artificial intelligence tools, without referencing in accordance with stated University requirements. Students need to seek approval from the Unit Coordinator within the first week of study if they intend to use some of their previous work in an assessment task (self-plagiarism).

Unauthorised collaboration (collusion)

Working with other students and submitting the same or substantially similar work or portions of work when an individual submission was required. This includes students knowingly providing others with copies of their own work to use in the same or similar assessment task(s).

Contract cheating

Organising a friend, a family member, another student or an external person or organisation (e.g. through an online website) to complete or substantially edit or refine part or all of an assessment task(s) on their behalf.

Cheating in an exam

Using or having access to unauthorised materials in an exam or test.

Serious outcomes may be imposed if a student is found to have committed one of these breaches, up to and including expulsion from the University for repeated or serious acts.

ECU's policies and more information about academic integrity can be found on the student academic integrity website.

All commencing ECU students are required to complete the Academic Integrity Module.

Assessment Extension

In some circumstances, Students may apply to their Unit Coordinator to extend the due date of their Assessment Task(s) in accordance with ECU's Assessment, Examination and Moderation Procedures - for more information visit https://askus2.ecu.edu.au/s/article/000001386.

Special Consideration

Students may apply for Special Consideration in respect of a final unit grade, where their achievement was affected by Exceptional Circumstances as set out in the Assessment, Examination and Moderation Procedures - for more information visit https://askus2.ecu.edu.au/s/article/000003318.
