ENEX13002 - Power Electronics
Term 2 - 2017


All details in this unit profile for ENEX13002 have been officially approved by CQUniversity and represent a learning partnership between the University and you (our student). The information will not be changed unless absolutely necessary and any change will be clearly indicated by an approved correction included in the profile.

Overview

This unit is based on your knowledge on electronics 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 also learn to calculate thermal dissipation requirements of power semiconductors and to choose suitable heat sinks. You will be introduced to the concepts of alternating current (AC) to direct current (DC), DC to DC, and DC to AC circuits, pulse width modulation (PWM) control, and chopper circuits. You will also learn about different types of motors and their control including DC motor control, AC motor control and stepper motor control schemes. You will learn to simulate power electronic circuits and develop power electronics solutions industrial problems. Students enrolled in distance mode are required to attend a compulsory Residential School.

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%). Consult the University’s Grades and Results Procedures for more details of interim results and final grades.
