This course is about power processing using control, signal processing and electronic systems. The application can be from many megawatts in an electric train or a wind farm to less than a few watts in a digital camera or a mobile phone. For modern power electronics system, computer simulation tools are used to analyse and optimise a design before any prototyping. Topics covered in this course are a) power electronic systems and applications such as motor drive, renewable energy and power supply systems; b) energy conversion topologies; c) modelling and control; d) design factors and computer simulations.
ELEC4410 covers the application of electronics to process or control power. The power electronic applications cover wide range that spans from megawatts in an electric train to less than one watt in a digital camera or mobile phone. The integration of power electronics has become unavoidable in electrical or electronic equipment. For modern designs, computer simulation tools are used to fully test and optimise a design prior to manufacture. The principles learnt in this course can be applied to many other areas of electronics too. Topics covered include:
• Overview of power electronic systems andﾠapplications: motor drive, renewable energy, power quality
• Semiconductor switches
• Diode rectifiers
• Controlled (SCR) rectifiers
• DC-DC converters: non-isolated
• DC-DC converters: isolated
• Single and three-phase inverters: topology and modulations
• Multi-level inverters: topology and modulations
• Averaging methods to model power converters
Based on the previous year's student feedback, the hardware experiment has been added as a new part of this course to enhance the understanding of the theories in power electronics. This will also provide students with more hands-on experience in power electronics design.
Course requirements
Assumed background
The only official prerequisite is ELEC3400 (Electronic Circuits)ﾠ This is not essential, but you may find some of the contents difficult without it. However, ELEC2003 (Electromechanics & Electronics) and ELEC2004 (Circuits, Signals & Systems) are certainly expected.ﾠIf you need to, remind yourself of the material from ELEC2003 and ELEC2004.
It will also be helpful to have some knowledge of power and machines from Electrical Energy Conversion & Utilisation ELEC3300 and some of control from Introduction to Control Systems METR4201. These are not necessary, but certainly desirable.
Prerequisites
You'll need to complete the following courses before enrolling in this one:
ELEC2400 or ELEC3400
Incompatible
You can't enrol in this course if you've already completed the following:
ELEC4400, ELEC7402

Additional course grading information
Your final mark will be calculated from your marks on the following assessment items:
(a) Tutorial question submission
(b) Computer Labs using Matlab/Simulink
(c) Experiment Labs based on hardware
(d) Final Examination
- The marks will be rounded to the nearest whole number before the grade cutoffs are applied. For example, 84.9 will be rounded to 85 and will receive a grade of 7 and 74.4 will be rounded to 74 and will receive a grade of 5.
- Furthermore, to get a grade of 4 and above, you are required to get at least 40% from the final exam (i.e. you must get at least 20 marks from 50 marks). If 40% (20 marks) in the final exam are not achieved, then the grade will be capped to 3.
