Sample subject outline - Semester 2 2013
Note: Subject outlines often change before the semester begins. Below is a sample outline.
Rationale
Power processing or energy conversion can be considered as one of the major applications of electronics in industrial applications. A broad understanding of basic industrial electronic circuits and systems will provide the foundation not only to design advanced power processing circuits for complex systems but also to operate and maintain them properly. This type of background will be beneficial for all electrical engineering disciplines.
Aims
The aim of this unit is to introduce you to the principles of operation and raise awareness on system oriented designs and control aspects of basic power electronic circuits and systems used in industrial applications.
Objectives
On completion of this unit you should be able to:
- Interpret the characteristics of power semiconductor devices such as power diodes, thyristors, BJT, GTO, IGBT etc.
- Describe the principle of operation of commonly known power electronic circuits.
- Analyse and design common types of diode and thyristor converters, voltage source inverters, DC-DC choppers and switched mode power supplies.
- Use simulation tools to model and analyse simple power electronic circuits
- Perform experiments on power electronic hardware circuits; obtain measurements and observe various electrical parameters.
- Troubleshoot an unexpected behaviour of a simple power electronic circuit.
Content
The following topics will be discussed in this unit:
- Introduction to Industrial Electronics
- Power Semiconductor Switches and Driver Circuits
- Heat sink Design, Measurements and Interfacing
- AC to DC rectifiers
- AC to DC Controlled Rectifiers
- Switched Mode regulator Design (DC to DC)
- Flyback and Forward Converter Design (DC to DC)
- DC to AC Inverters
- PWM Theory
- DC Motor Drives
The unit content and associated activities have been designed to facilitate learning and develop professional capabilities of learners to:
- Plan and apply a problem solving approach to analyse and design a circuit for a given industry application.
- Work independently and collaboratively to improve learning outcomes.
- Communicate technical issues in verbal and in written form.
Approaches to Teaching and Learning
Teaching mode:
Total: 4 hrs/wk
Lectures: 2 hrs/wk
Tutorials: 1 hr/wk
Laboratories: 1 hr/wk
The main theoretical concepts with examples and applications are covered in lectures followed by a 1 hour interactive problem solving tutorial, and an average of 1 hour of laboratory work, per week to relate theory to practice.
Laboratory work comprises two computer laboratories and two practical laboratory exercises. These exercises will help you to develop practical skills while the oral questions will assist communication of technical issues as well as your understanding of the pragmatic aspects of the course material. All necessary learning resources will be made available online for student access.
Assessment
The assessment items incorporated in this unit comprises two computer laboratories, two laboratory experiments and one written examination.Computer Laboratories and Practical Laboratories will be assessed during the session itself and you will be provided with immediate feedback. Additionally, these marks will be uploaded to the blackboard site for your informationafter each session.
You will also receive formative feedback on your progress in the unit communicated verbally during lectures, tutorials, lab classes as well as in written form via blackboard discussions. Individual guidance will also be provided during lectures, tutorials and lab classes.

Problem Solving Task
Description:
In this task, you will gain experience on computer simulation of power electronics circuits. You will be given simulation files of circuits to study under the unit where you are required to run the simulations and complete a task sheet. This task sheet will be assessed during the session itself and the final mark will be based on written answers and oral justification. This assessment item is run on two different weeks as two separate components.

Risk assessment statement
You will undertake lectures and tutorials in the traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit.
You will be required to undertake practical sessions in the laboratory under the supervision of the lecturer and technical staff of the School. In any laboratory practicals you will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective items (e.g. closed shoes or steel capped shoes).
You will undergo a health and safety induction before the commencement of the practical sessions and will be issued with a safety induction card. If you do not have a safety induction card you will be denied access to laboratories.
Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
