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 Use knowledge of real and reactive power and power factor when analysing electric circuits in single and 3-phase circuits.
2 Calculate the performance of the single-phase transformer using equivalent circuit model.
3 Evaluate the performance of DC and AC machines when loaded.
4 Compute the basic operation of 1-phase rectifiers and 1-phase controlled rectifiers.
5 Use the understanding of transformer and DC machine characteristics in a laboratory setup or by using a software package.

Indicative Module Content
1-phase and 3-phase circuits, real and reactive power, principle of three phase generation. Characteristics of single-phase ideal and practical transformers. Principle of operation, concept of leakage inductance and influence on transformer operation, use of equivalent circuit for performance analysis. DC machines, equivalent circuit, emf and torque equations, motor drive characteristics, motor control. 3-phase induction motor, construction and operating principle, basic drive characteristics.
