MODULE DETAILS

Power Electronics and Variable Speed Drives DEEPEV616

NOMINAL DURATION IN HOURS

60 hours total time commitment

This time commitment includes the structured activities, preparation reading, and attendance at each webinar, completing exercises, practical assessments and proctored assessments.

It is also expected that students spend additional time on readings, personal study, independent research and learning, practicing on remote labs and required software and working on any projects and assignments.

This module covers applications of power electronics and devices in power industry, designing/sizing of switched mode power supply (SMPS) and their components, variable speed drives (VSD) for motor speed control and their applications, control and protection of VSD, electro-magnetic compatibility issues, troubleshooting of VSD equipment. The problems that can be introduced by SMPSs and VSDs such as ripple, harmonics, electrostatic discharge and electromagnetic compatibility/ electromagnetic interference (EMC/EMI) problems are also covered.

MODULE PURPOSE

The purpose of the module is for participants to develop knowledge of the applications of power electronics and variable speed drives, building a broad comprehension of the different types and designs that have become essential for reliable operation of complex electrical equipment.

ASSESSMENT STRATEGY

METHODS OF ASSESSMENT

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, structured assessments, samples and questioning. This will include short answer questions on the knowledge content, the use of remote and virtual labs, and writing tasks to apply the learning to academic tasks.

CONDITIONS OF ASSESSMENT

Assessor Requirements:

Assessors must satisfy the assessor requirements in the standards for registered training organisation (RTOs) current at the time of assessment.

Assessors must also hold a tertiary qualification in engineering or related field.

The RTO must also ensure that trainers and assessors keep their industry knowledge up to date through ongoing professional development.

Assessment Conditions:

Questioning techniques should not require language, literacy and numeracy skills beyond those required in this module. The candidate must have access to all tools, equipment, materials and documentation required.

The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Assessments may be open book assessment and may be completed off campus. Invigilation software will be used for some assessments to ensure authenticity of work completed.

Model answers must be provided for all knowledge-based assessments to ensure reliability of assessment judgements when marking is undertaken by different assessors.
