Overview
Power Electronics deals with the study of semiconductor devices and their applications in in the industry. Power semiconductor devices, such as the diode, thyristor, triac and power transistor, are used in applications as switching devices. The modern electrical engineer requires knowledge of these devices and their applications in rectification, inversion, frequency conversion, dc and ac machine control, renewable energy and switch-mode power supplies. Engineers need to be aware of the undesirable effects that any power electronic equipment imposes on both the supply system and the load, and how these effects may be minimised.
Course learning outcomes
The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:
- compare the characteristics of common power semi-conductor devices;
- evaluate rms and mean values of typical waveforms;
- analyse common power electronic circuits quantitatively;
- select motor torque ratings for particular applications;
- analyse DC adjustable speed drive systems quantitatively;
- select AC adjustable speed motor/drive combinations to meet specified requirements;
- design drive circuits for power electronic switches to meet required switching performance;
- evaluate the relative benefits of snubber circuits;
- analyse the performance of power electronic converters in renewable energy applications.
