This module is an introduction to Power Electronics and it is assumed that the student has studied circuit theory and electrical machines prior to embarking on this course. Considerations of static and dynamic characteristics of power semiconductor devices including thermal aspects are followed by the analysis and design of principal types of power converters. Key applications are also considered so that the module provides a broad knowledge and skills in the field of power electronics.

Power semiconductor devices: Static and Dynamic Characteristics, loss mechanisms, thermal aspects, heat sink selection, interfacing control electronics with power devices.

Naturally commutated converters: Single phase and three phase converter topologies, operation with passive and active loads, inverter operation, and qualitative treatment of overlap.

Self-Commutated Converters: basic concepts, pulse width modulation, application to motor drives and power systems.

Waveform Distortion: Power electronic sources of waveform distortion, Displacement and Distortion factors.

This module is taught over one semester with a mixture of taught lectures, tutorials, and laboratory sessions, supported by independent student learning, research, guided reading, and on-line webcast/videos.

1. Explain the capabilities and limitations of power semi-conductors devices and use them in a variety of power electronic circuits. (AHEP 3: SM1b, P1, P2)

2. Analyse and design power electronic circuits. (AHEP 3: EA2, EA3b, EA4b, D3b, P2, P8)

3. Investigate a power electronic system experimentally and communicate results orally and by a written report. (AHEP 3: EA2, EA3b, D3b, P8)

You will be required to complete two elements of summative assessment as follows:

Examination (2 hours): 70% assessing LO 1 and 2. Meeting AHEP 3 Outcomes SM1b, EA2, EA3b, EA4b, D3b, P2, P8.
Technical Report (1,000 word approx.): 30% assessing LO 3. Meeting AHEP 3 Outcomes EA2, EA3b, D3b, P8.

Practice formative class tests will be undertaken during the module and formative guidance and feedback will be provided in tutorial sessions within the class.
