Overview
This is a higher level unit that aims to introduce the principles of operation of basic power electronic circuits and systems used in industrial applications. This unit enables the learner to understand, interpret and compare the characteristics of power devices such as power diodes, thyristors, BJT, MOSFET, IGBT etc.; analyse common types of diode and thyristor converters, inverters, and DC-DC converters; use simulation tools to model and analyse simple power electronic circuits; perform experiments on power electronic hardware circuits; obtain measurements. Power processing can be considered as one of the major applications of electronics in industry applications. A broad understanding of 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. Such knowledge is essential for a graduate electrical engineer who intends to work in industry.
Learning Outcomes
On successful completion of this unit you will be able to:
- Describe the principles and concepts of power electronics, including characterising and comparing power semiconductor switches, passive devices and converter topologies at a mastered level.
- Describe, analyse and design power electronic circuits and systems comprising microcontrollers, semiconductor devices and power semiconductor switches considering factors such as efficiency, power factor, and reliability at a mastered level.
- Acquire hands-on experience through laboratory work and projects, allowing application of theoretical knowledge to practical applications using circuit design software and laboratory experimental setups.
- Develop skills in component acquisition, thermal design and technical documentation in view of improving the power quality of electronic systems, addressing issues like harmonic distortion at mastered level.
Content
- Overview of power electronic systems and application areas
- Power semiconductor switches and switch driver circuits
- Review of basic circuit components and computer simulation techniques for power electronic design
- Non-isolated DC-DC converters, isolated DC-DC converters
- Switched-mode inverters, AC & DC Motor drive applications
- Controlled (thyristor) and uncontrolled (diode) rectifiers
- Power Electronics Applications in FACTS/HVDC, renewable energy, residential & industrial sector.
Key concepts introduced are the use of inductors and capacitors as energy storage components, the operation of semiconductor devices as power switches, and steady-state switching circuit analysis.
Learning Approaches
The unit places an emphasis on practical learning, with two 3-hour laboratory practicals and computer simulations. Students will work in groups using circuit design and analysis software and laboratory experimental setups to apply theoretical knowledge to practical appliations.
Learning &Teaching Approaches: 4 hours per week contact: 2 hrs - lecture. Preparatory study from set textbook and/or online notes. 2 hr tutorial (independent working on problems with assistance, where possible linked to prep for labs). In addition there will be 6 hrs practical laboratory work. In groups, students will conduct tests on a real power electronic hardware circuitry on the power electronic testbed and observe and measure input and output parameters using the data acquisition system. Students will submit a draft and then final copy of preparation, results, analysis and discussion. Students will simulate given power electronic circuits, analyse, discuss and report the results.
Feedback on Learning and Assessment
Students will receive formative feedback on your progress in the unit communicated verbally during lectures, tutorials, and lab classes and through QUT Canvas. Written feedback will be provided on completion of the project and practical laboratory work. Individual guidance will also be provided during lectures, tutorials and lab classes.
Assessment
Overview
The unit will be assessed based on three items:
1. Project
2. Practical laboratory/simulation work
3. Examination (written)
Unit Grading Scheme
7- point scale
Assessment Tasks
Assessment: Project
Students will design a pulse width modulated converter. They will use simulation tools for their design and submit progress reports and a final technical report. Peer and self assessment will be used for the moderation of grades in addition to other means.
This assignment is eligible for the 48-hour late submission period and assignment extensions.
The use of generative artificial intelligence (Gen AI) tools is allowed for the purpose of understanding this assessment task and summarising information when cited appropriately. As part of your submission, attach a copy of all assessment related Gen AI prompts along with the generated responses as a separate .pdf file.
Assessment: Practical laboratory work
Several laboratory experiments will run during semester. Students will submit their preparation records, experimental setup, experimental results, and analysis and discussion of results. Peer and self assessment will be used for the moderation of grades in addition to other means.
The late submission period does not apply and no assignment extensions are available.
The use of generative artificial intelligence (Gen AI) tools is allowed for the purpose of understanding this assessment task and summarising information when cited appropriately. As part of your submission, attach a copy of all assessment related Gen AI prompts along with the generated responses as a separate .pdf file.
Assessment: Examination (written)
A set of questions on major concepts and problem solving from all the unit material.
“On Campus invigilated Exam. If campus access is restricted at the time of the central examination period/due date, an alternative, which may be a timed online assessment, will be offered. Individual students whose circumstances prevent their attendance on campus will be provided with an alternative assessment approach.”
Academic Integrity
Academic integrity is a commitment to undertaking academic work and assessment in a manner that is ethical, fair, honest, respectful and accountable.
The Academic Integrity Policy sets out the range of conduct that can be a failure to maintain the standards of academic integrity. This includes, cheating in exams, plagiarism, self-plagiarism, collusion and contract cheating. It also includes providing fraudulent or altered documentation in support of an academic concession application, for example an assignment extension or a deferred exam.
You are encouraged to make use of QUT’s learning support services, resources and tools to assure the academic integrity of your assessment. This includes the use of text matching software that may be available to assist with self-assessing your academic integrity as part of the assessment submission process.
Breaching QUT’s Academic Integrity Policy or engaging in conduct that may defeat or compromise the purpose of assessment can lead to a finding of student misconduct (Code of Conduct – Student) and result in the imposition of penalties under the Management of Student Misconduct Policy, ranging from a grade reduction to exclusion from QUT.
Resources
The primary source of information will be the weekly lectures. All lectures will be recorded and released as videos. Lectures will be supported by weekly presentation files (powerpoint / pdf) and other supplimentary materials.
Each major topic will be supported by recommended reading either from the list of recommended texts, or specific chapters or other material made available ahead of time.
Freely available software tools (for example circuit simulators) will be recommended along with example circuits released to students to allow them to explore concepts delivered in the unit.

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 have to do practical work for the project in the laboratory under the supervision of technical staff of the School. You will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective clothing (e.g. closed shoes). You will undergo a health and safety induction before being allowed access to laboratories.
QUT has a formal risk assessment process which can be used to determine the types or risks and how you should handle them.
