COURSE NAME: Power Electronic Converters

COURSE CODE: EEET2669

TEST TITLE: End-of-Semester Test

Learning Outcomes

Specific learning outcomes from the Course Guide

Select and design power electronic converter topologies for a broad range of energy conversion applications.

Analyse and simulate the performance of power electronic conversion systems

Experimentally evaluate the performance of power electronic conversion systems.

Design and analyse closed loop regulators for DC and AC converter applications.

Overview of Test | Exam:

There will be an end-of-semester test in week 11. The scope of this test will cover material ranging from three phase inverter modulation through to linear DC and AC current regulation. The test will contribute 15% of your final mark for this course.

The assessment criteria includes:

Topology identification. You will need to demonstrate an ability to recognise, sketch and manipulate different classes of inverter and DC-DC converter. You should be able to sketch their circuit topologies with the correct semiconductor devices, as well as describe their operating modes and discrete switched states.

Waveform sketching. You will need to draw operating converter and inverter waveforms. Marks will reflect:

o Identification of the correct switching modes, conduction intervals, DC bias levels, etc.

o Synchronisation and alignement of sub-waveforms (eg. current, voltage, power)

o Clear scales, axes and units

o Correct identification of waveform features (e.g. duty cycles, pulse-widths, vector sequences, etc.)

Waveform analysis. You will need to demonstrate an ability to develop analytical expressions for key converter waveforms using the formula sheet as a resource.

Computational ability. You will need to demonstrate your ability to calculate key properties of converter and inverter behaviour. Marks will be awarded based on identification of the correct methodology and numerical accuracy of the final results.
