The unit begins by considering electrical machines, looking at DC machines, induction motors, synchronous motors and other types of motors under fixed and variable speed operation. Then thyristor rectifiers and switched power converters are presented, looking at their use for electrical energy conversion in general and variable speed motor control in particular. Finally, single and three phase AC networks, power factor correction, and electrical power generation, transmission and distribution networks are explored. Particular focus is given here to three phase transformers, transmission line modelling, quality of electrical supply, electrical protection systems, and power system control.


At the successful completion of this unit you will be able to:

  1. Analyse a 3 phase AC network.
  2. Describe DC/AC and DC/DC power conversion techniques.
  3. Apply power conversion techniques to a renewable energy system.
  4. Describe electromechanical conversion systems.
  5. Use power convertors to drive induction and synchronous machines.


Continuous assessment: 40%

Examination (2 hours): 60%

Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

Workload requirements

3 hours lectures, 3 hours laboratory and practice classes and 6 hours of private study per week
