Aims of Module
To provide the student with an understanding of electric power circuits and the ability to apply fundamental electromechanical energy conversion principles to drive problems.

Learning Outcomes for Module
On completion of this module, students are expected to be able to:
1 Solve electric circuit problems involving real and reactive power and power factor in single and 3-phase circuits.
2 Describe the physical structure of a single- phase power transformer and use an equivalent circuit model to analyse the performance of the transformer.
3 Explain the principles of operation of dc and ac machines and analyse their performance when loaded.
4 Explain the basic operation of 1-phase rectifiers and 1-phase controlled rectifiers.
5 Solve simple electric circuit problems that demonstrates understanding of transformer and dc machine characteristics in a laboratory setup

Indicative Module Content
