Overview
In this unit, you will learn to select power electronics solutions for industrial problems and simulate selected power electronic circuits. You will also learn the practical applications of power electronics circuits in complex systems such as renewable energy integration and electric/hybrid vehicle energy management systems. This unit is based on your knowledge of electronics and electrical machines you previously studied. In this unit, you will learn about power semiconductors such as Diacs, silicon controlled rectifiers (SCR), metal oxide silicon field-effect transistors (MOSFET), isolated gate bipolar junction transistors (IGBT), their symbols, and theory of operation and limitations. You will be introduced to the concepts DC to DC, and DC to AC circuits, and pulse width modulation (PWM) control circuits. You will also learn about different types of motor control and drive systems including DC motor control, AC motor control, and stepper motor control schemes. Students enrolled in online mode are required to attend a compulsory residential school.

Assessment Overview
Assessment Grading
This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%). Consult the University’s Grades and Results Policy for more details of interim results and final grades.

3 Practical and Written Assessment
Laboratory sessions are to be held during Residential School, currently only on the MACKAY campus. Refer to the Handbook for dates.
This assessment item consists of a series of laboratory experiments on plug-and-play power electronic circuits and drives.
Teams of 2 students should be formed, and only ONE combined report needs to be submitted by BOTH students.
Each student should submit a personal signed cover page declaring the team work done, specifying the other team member's name.
Each heading of the report should show the responsible team member's name in brackets.
Team reports must be professional and typed, including references.
Photographic evidence is required to prove that the various circuits were constructed and measurements were obtained - for this reason it is required that a team member's hand or fingers be included in all your photographs as a 'signature'.
Laboratories are compulsory and all students must attend and pass all laboratory assessments in order to pass the unit.
Detailed explanations of these experiments and how to carry them out will be posted on the unit website at the start of the term.
Week 12 Thursday (1 June 2023) 11:00 pm AEST
Each student should submit a .PDF copy of their combined 2-person professional team report.
It is endeavoured to provide feedback within 2 weeks of submission.
Laboratory Exercise Reports will be graded using the following criteria:
- Correct description of laboratory concepts and procedures;
- Correct calculations, analysis and thinking;
- Photographic evidence that circuits were constructed by the team;
- Correct measurements, answers and units;
- Photographic and other evidence that correct results / measurements were obtained by the team;
- Discussion and understanding of laboratory results;
- Team reports must be professional and typed, including references;
- All laboratory exercises must be attempted.
- Compare and select power electronic components, converters, and drives for renewable energy integration and electric vehicles
- Analyse and model the operation of single-phase and three-phase power electronic circuits, including alternating current (AC) to direct current (DC), AC to AC, DC to DC, and DC to AC topologies

4 Take Home Exam
The End of Term Online Test will be released via Moodle at 09:00 am AEST on the day (timetable to be published towards the end of term).
This will be an 'open resource' exam including the internet, but you will be required to sign a declaration of individual work done.
No contact is allowed with fellow students or any person proficient in the field, i.e. neither virtual contact via the Moodle forums, nor using any communications technology to exchange information etc.
5 Hours will be allowed (due 14:00), but this includes scanning and uploading.
It is strongly advised to take one or more break during the 5-hour period and also to eat and drink something.
Late penalties will be deducted at 20% per hour (or proportional part).
Questions during the 5-hour period will be taken via email and where necessary, responses will be sent out to everyone via Q&A emails.
To be written during the exam period. Please consult the unit Moodle page closer to the time.

As a CQUniversity student you are expected to act honestly in all aspects of your academic work.
Any assessable work undertaken or submitted for review or assessment must be your own work. Assessable work is any type of work you do to meet the assessment requirements in the unit, including draft work submitted for review and feedback and final work to be assessed.
When you use the ideas, words or data of others in your assessment, you must thoroughly and clearly acknowledge the source of this information by using the correct referencing style for your unit. Using others’ work without proper acknowledgement may be considered a form of intellectual dishonesty.
Participating honestly, respectfully, responsibly, and fairly in your university study ensures the CQUniversity qualification you earn will be valued as a true indication of your individual academic achievement and will continue to receive the respect and recognition it deserves.
As a student, you are responsible for reading and following CQUniversity’s policies, including the Student Academic Integrity Policy and Procedure. This policy sets out CQUniversity’s expectations of you to act with integrity, examples of academic integrity breaches to avoid, the processes used to address alleged breaches of academic integrity, and potential penalties.
What is a breach of academic integrity?
A breach of academic integrity includes but is not limited to plagiarism, self-plagiarism, collusion, cheating, contract cheating, and academic misconduct. The Student Academic Integrity Policy and Procedure defines what these terms mean and gives examples.
Why is academic integrity important?
A breach of academic integrity may result in one or more penalties, including suspension or even expulsion from the University. It can also have negative implications for student visas and future enrolment at CQUniversity or elsewhere. Students who engage in contract cheating also risk being blackmailed by contract cheating services.
Where can I get assistance?
For academic advice and guidance, the Academic Learning Centre (ALC) can support you in becoming confident in completing assessments with integrity and of high standard.
