Module summary

The teaching and assessment methods shown below will be kept under review during 2020-21. In particular, if conditions allow for alternative formats of delivery, we may amend the timetable and schedule appropriate classes in addition to (or in place of) the Online Learning Workshops. For Semester 2 (from January 2021), we anticipate that this will be most likely, in which case online teaching will be substituted for traditional face-to-face teaching methods, including lectures and practical classes. ‘Independent online learning’ will involve watching pre-recorded lecture material or screen-casts, engaging in learning activities such as online worked examples or remote/virtual laboratory work, etc. Students will be expected to fully engage with all of these activities. The time commitment for independent online learning, and also the frequency and duration of Online Learning Workshops, are approximate and intended as a guide only. Further details will be confirmed when the module commences.

Objectives

Power electronics is the technology involving controlled conversion of electrical power. Whilst many new topologies and their control methods are still being developed, the understanding of their basic principles and their effects on the existing electrical systems is particularly desirable as they are becoming more popular among many engineering systems. This module gives students the right level of analytical skills and knowledge to design and apply a power converter for various applications.

Objectives: To learn the basics of three-phase circuits, connections, voltage and current analysis and real and reactive power calculations.To learn the fundamentals of electricity conversion from the form supplied by the source to the forms required by the load.To understand power electronic conversion techniques, including the basic converters (DC-DC, AC-DC and DC-AC) and their power switching and control methods.To learn the methods of circuit analysis applicable to switched mode circuits.To gain familiarity with the essential properties of the relevant semiconductor devices.To be able to design simple converters for practical applications.

Learning outcomes
On completion of this module students should be able to:

1. To understand the principles of power control by switching; demonstrate the benefits of switched mode circuits; familiarise with the commonly used semiconductor switching devices.
2. To demonstrate a full understanding on several DC-DC converters; perform analysis on their operation principles; develop design equations for selecting their components.
3. To be able to explain how the steady-state AC voltage and current are related to each other in power circuits using phasor analysis.
4. To understand and be able to quantify active, reactive and apparent power.
5. To comprehend the operation principles for several thyristors based rectifiers; quantify the current harmonics and the average power drawn by a rectifier.
6. To understand the H-bridge based inverters and their several control methods; develop the skills in analysing the different modes of operations for the inverters; gain the understanding on how the power is delivered or absorbed by grid-connected inverters.
