Module Aims | |||||||||||||||||||||||||||||||||
To impart an introductory understanding of power electronics and, working from first principles, to introduce the techniques of analysis and design of power semiconductor controlled circuits and systems. The semiconductor devices are assumed ideal, thus allowing the focus of attention to be on the energy converter topologies used and their application.

Contribution to Programme Outcomes:
Teaching & Learning Strategies/Assessment Methodology: The module is delivered using lectures, tutorials and lab sessions. In each lab session, the circuits that are introduced, and whose operation are described in the lectures, are further examined by the students using Pspice. The exam involves explaining the operation of various power electronics circuits and solving relevant problems (85% of overall mark). The assignment involves the design of a controller for a buck converter (15% of overall mark). It involves working as an individual. Pspice and MATLAB are employed in the design and verification of the controller. Each student must submit a report detailing their work. | |||||||||||||||||||||||||||||||||
