ENAX12001 - Power Electronics Applications

General Information

Unit Synopsis

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.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Written Assessment 20%
2. In-class Test(s) 20%
3. Practical and Written Assessment 20%
4. Take Home Exam 40%

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%).
