Lecture/Tutorial Thursday 6pm - 8pm Online
Context and Aims
Power electronic circuits are an essential component of renewable and distributed energy sources including wind
turbines, photovoltaics, marine energy systems and energy storage systems. They are also finding increasing
use in other utility applications including active power filters, VAr compensator, dynamic voltage restorers and
HVDC transmission systems. Electronic processing of electrical power for these applications also provides the
means to control these elements of the electrical grid and its generation sources.

The course is aimed at students who have already been introduced to a first course in Power Electronics which
covers steady-state characteristics of various AC-DC, DC-DC, and DC-AC converter circuits. The fourth-year
elective course ELEC4614 – Power Electronics offered by EE&T, UNSW, is such a course. The objective of
ELEC9711 is to show how these converter topologies are utilised in renewable energy systems (wind and PV), in
utility applications (for example HVDC) and to further investigate the converters in terms of their efficiency, control
characteristics, description of dynamics and their closed-loop control. Some advanced converter topologies,
especially in the context of large and complex applications, which are beyond the scope of a first course in power
electronics, are also treated.

The course also introduces students to computer modelling of power electronic converters and their control
circuits using modern simulation platforms like LTSpice, PLECS, PSIM or SimPower in Matlab-Simulink.

graduate capabilities (listed in Appendix B). This course also addresses the Engineers Australia (National
Accreditation Body) Stage I competency standard as outlined in Appendix C.
Syllabus
The topics to be covered in this course will include: Grid integration of electrical power from renewable sources;
Current and voltage control; Advanced topics in DC-DC converters, inverters, AC-DC converters and AC-AC
converters for use in utility interfacing; resonant converters for DC-DC conversion; converter circuit and system
modelling using LTSpice or other simulation platforms, device selection and their modeling, component selection
and design, and case studies of converter system designs.

TEACHING STRATEGIES
Delivery Mode
The teaching in this course aims at establishing a good fundamental understanding of the areas covered using:
• Online lecture videos and screencasts which explain the important concepts for each topic of the course;
• Formal lectures/tutorials, which provide you with alternative explanations to aid your understanding. They
also allow for exercises in problem solving and allow for time for you to resolve problems in
understanding of lecture material;
ELEC9711 – Term 3, 2020 – Course Outline
Page 4

• Design and simulation work, which supports the lecture video material and also provides you with skills
necessary to perform a design task.
Learning in this course
You are expected to attend all lecture/tutorial classes in order to maximise learning. You should watch the
relevant online lecture videos before attending the lecture/tutorial classes. Reading additional texts will further
enhance your learning experience. Group learning is also encouraged. UNSW assumes that self-directed study
of this kind is undertaken in addition to attending formal classes throughout the course.
Tutorial classes
Five to six tutorial sheets may be expected. The problem-solving sessions will be on most recently covered
topics. Additionally, online PSIM or LTSpice sessions may be arranged. Students will be expected to participate
vigorously during these sessions, in the form of questions, suggested solutions and methods. Participation by
students and the tutor should be viewed as desirable aspects of these sessions.

You should attempt all of your problem sheet questions in advance of attending the tutorial classes. The
importance of adequate preparation prior to each tutorial cannot be overemphasized, as the effectiveness and
usefulness of the tutorial depends to a large extent on this preparation. Group learning is encouraged. Answers
for these questions will be discussed during the tutorial class and the tutor will cover the more complex questions
in the tutorial class. In addition, during the tutorial class, 1-2 new questions that are not in your notes may be
provided by the tutor, for you to try in class. These questions and solutions may not be made available on the
web, so it is worthwhile for you to attend your tutorial classes to gain maximum benefit from this course.

ASSESSMENT
The assessment scheme in this course reflects the intention to assess your learning progress through the term.
Ongoing assessment occurs through the three assignments.
Assignments

The assignments allow self-directed study leading to the solution of a design task or theoretical questions. Marks
will be assigned according to how completely and correctly the design problem or theoretical question has been
addressed.

The assignments will be released in week 2 (10%, submit week 4), week 5 (10%, submit week 7) and week 8
(20%, submit week 10). You are expected to submit any requested formal materials to the school office (or, if
specified by Moodle) by 3pm, Friday of the indicated week. Late submissions will attract a penalty of 10% per day
(including weekends).

You are expected to submit an individual solution/report/design for each assignment for ELEC9711 not a group
report. The marks from your assignments will contribute 40% of your final class mark. Late submissions will not
be accepted. You must include a signed cover sheet http://scoff.ee.unsw.edu.au/forms/assignmentcover.pdf
declaring that the work submitted is your own work and this must be the first page of the report.

Final Exam

The exam in this course is a two-hour written examination, comprising four questions from which students select
to answer only three questions. Only University approved calculators are allowed. The examination tests
analytical and critical thinking and general understanding of the course material in a controlled fashion. Questions
may be drawn from any aspect of the course unless specifically indicated otherwise by the lecturer. Marks will be
assigned according to the correctness of the responses. Please note that you must pass the final exam in order
to pass the course.

Student Responsibilities and Conduct
Students are expected to be familiar with and adhere to all UNSW policies (see
https://student.unsw.edu.au/policy), and particular attention is drawn to the following:
Workload
It is expected that you will spend at least 15 hours per week studying a 6 UoC course, from Week 1 until the
final assessment, including both formal classes and independent, self-directed study. In periods where you need
to complete assignments or prepare for examinations, the workload may be greater. Over-commitment has been
a common source of failure for many students. You should take the required workload into account when
planning how to balance study with employment and other activities.
Attendance
Regular and punctual attendance at all classes is expected. UNSW regulations state that if students attend less
than 80% of scheduled classes they may be refused final assessment.
General Conduct and Behaviour
Consideration and respect for the needs of your fellow students and teaching staff is an expectation. Conduct
which unduly disrupts or interferes with a class is not acceptable and students may be asked to leave the class.
Work Health and Safety
UNSW policy requires each person to work safely and responsibly, in order to avoid personal injury and to protect
the safety of others.
Special Consideration and Supplementary Examinations
You must submit all assignments and attend all examinations scheduled for your course. You can apply for
special consideration when illness or other circumstances beyond your control interfere with an assessment
performance. If you need to submit an application for special consideration for an exam or assessment, you must
submit the application prior to the start of the exam or before the assessment is submitted, except where illness
or misadventure prevent you from doing so. Be aware of the “fit to sit/submit” rule which means that if you sit an
exam or submit an assignment, you are declaring yourself well enough to do so and cannot later apply for Special
Consideration. For more information and how to apply, see https://student.unsw.edu.au/special-consideration.
Continual Course Improvement
This course is under constant revision in order to improve the learning outcomes for all students. Please forward
any feedback (positive or negative) on the course to the course convener or via the Course and Teaching
Evaluation and Improvement Process. You can also provide feedback to ELSOC who will raise your concerns at
student focus group meetings. As a result of previous feedback obtained for this course and in our efforts to
provide a rich and meaningful learning experience, we have continued to evaluate and modify our delivery and
assessment methods. This includes changing the content of the class to include more renewables and distributed
generation and revising the assessment scheme. For the course delivered in 2017, the assessment schedule and
weighting were adjusted such that the final exam represents 60% of the final mark, with assignments and
coursework representing 40% in total. In 2019, the course underwent digital uplift and received a huge
investment in the production of online materials, key concept videos and podcasts. These were used in 2020 for
the first time.
