Unit description Unit description

This unit develops fundamental knowledge and skills in the area of power electronics converters and their typical applications. Foundation knowledge in semiconductor devices, passive components and general circuit analysis is assumed. The unit extends those fundamentals to electrical energy conversion systems operating with relatively high current and voltage levels. Topics covered include: an introduction on power semiconductors and converters; power computations essential in analysing and designing power electronics circuits; dc-dc converters and dc power supplies; single and three phase inverters and rectifiers; and power electronics applications. This unit uses problem/team based learning approach, where students have to choose a project topic and their team members, and then design, simulate, build and test a converter prototype. PLECS simulation tool and a control board are used in the development of the project.

General Assessment Information

Grading and Passing Requirement for Unit

  • In order to pass this Unit a student must obtain a mark of 50 or more for the Unit (i.e. obtain a passing grade P, CR, D, or HD).
  • For further details about grading, please refer below in the policies and procedures section.
  • If you receive special consideration for the oral presentation and demonstration of the Project, a supplementary conventional exam will be scheduled by the faculty during a supplementary exam period, typically about 3 to 4 weeks after the normal exam period. By making a special consideration application for the oral presentation and demonstration of the Project you are declaring yourself available for a conventional exam during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to applying. Approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.

Hurdle Requirements

  • Students must attend and participate in at least 6 of the 7 weekly PC Labs (Weeks 1-7) to pass this unit.
  • Students must attend and participate in at least 5 of the 6 weekly Project Labs (Weeks 8-13) to pass this unit.

Late Submissions and Re-submissions

  • Online quizzes, in-class activities, or scheduled tests and exam must be undertaken at the time indicated in the unit guide. Should these activities be missed due to illness or misadventure, students may apply for Special Consideration.
  • All other assessments must be submitted by 5:00 pm on their due date.
  • Should these assessments be missed due to illness or misadventure, students should apply for Special Consideration.
  • Assessments not submitted by the due date will receive a mark in accordance with the late submission policy as follows: 
    • A 12-hour grace period will be given after which the following deductions will be applied to the awarded assessment mark: 12 to 24 hours late = 10% deduction; for each day thereafter, an additional 10% per day or part thereof will be applied until five days beyond the due date. After this time, a mark of zero (0) will be given. For example, an assessment worth 20% is due 5 pm on 1 January. Student A submits the assessment at 1 pm, 3 January. The assessment received a mark of 15/20. A 20% deduction is then applied to the mark of 15, resulting in the loss of three (3) marks. Student A is then awarded a final mark of 12/20.
  • Re-submissions of work are not allowed.

Students are reminded of the University policies regarding assessment, academic integrity and disruption to studies.

Requests for extension on assessable work are to be made to the Unit Coordinator but will only be considered in the event of illness or misadventure.
