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 operation and describe the theory of power switching devices and their application in power converters.
  2. Apply relevant knowledge of power electronics to sustainable design and development practice.
  3. Demonstrate knowledge of the theory and operation of dc-dc, and single- and poly-phase ac-dc, dc-ac and ac-ac converters.
  4. Propose relevant control techniques in power electronics.
  5. Research new developments in the field of power electronics and reflect critically on their significance to engineering practice.
  6. Undertake problem identification, formulation and solution in the design of power electronic systems.

Unit Content

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

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 plan 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.

Academic Misconduct

Edith Cowan University has firm rules governing academic misconduct and there are substantial penalties that can be applied to students who are found in breach of these rules. Academic misconduct includes, but is not limited to:

  • plagiarism;
  • unauthorised collaboration;
  • cheating in examinations;
  • theft of other students' work;

Additionally, any material submitted for assessment purposes must be work that has not been submitted previously, by any person, for any other unit at ECU or elsewhere.

The ECU rules and policies governing all academic activities, including misconduct, can be accessed through the ECU website.
