Aims and Fit of Module

The aim of this module is to provide a good understanding of the power-electronic components and the behaviour of power-electronic converters by presenting systematically all important aspects of semiconductor devices and the common type of electric-power controllers. It is designed to explore the fundamentals of AC-DC, AC-AC, DC-DC, and DC-AC converters operation. The module also emphasize on the study of salient features of power diodes, power transistors, MOS-controlled thyristor, silicon controlled rectifier and other members of thyrstor family. With solid understanding of these concepts, students are expected to clearly present the operation, characteristics, and limitations of semiconductor-based converters that are being extensively employed in systems where power flow is required to be regulated.

Learning outcomes

A. Apply the operating principles of switched-mode converters to be used in various electronic devices.
B. Calculate and analyze the steady-state voltages and currents for different types of power converters, including step-down, step-up, and inverting converters, using appropriate mathematical techniques.
C. Conduct laboratory experiments on AC-DC and DC-DC converters and critically analyze the results under diverse circuit conditions to draw meaningful conclusions.

Method of teaching and learning

This module employs an integrated approach to teaching and learning, combining theoretical knowledge delivered through the formal lectures every week with hands-on practice via laboratory sessions to ensure students develop a deep and practical understanding of power electronic converters. The module is expected to deliver through a combination of interactive lectures including tutorials, practical lab sessions, and independent self-study. Lectures serve as the foundation for introducing basic power electronic converters such as AC-DC, DC-DC, AC-AC, DC-AC converters and their characteristics. Tutorials will be designed to practice the exercise problems that are associated with the topics delivered in formal lectures.
