Module summary

Power electronics is the technology involving controlled conversion of electrical power. Whilst many new topologies and their control methods are still being developed, the understanding of their basic principles and their effects on the existing electrical systems is particularly desirable as they are becoming more popular among many engineering systems. This module gives students the right level of analytical skills and knowledge to design and apply a power converter for various applications.

Objectives

To learn the basics of three-phase circuits, connections, voltage and current analysis and real and reactive power calculations.
To learn the fundamentals of electricity conversion from the form supplied by the source to the forms required by the load.
To understand power electronic conversion techniques, including the basic converters (DC-DC, AC-DC and DC-AC) and their power switching and control methods.
To learn the methods of circuit analysis applicable to switched mode circuits.
To gain familiarity with the essential properties of the relevant semiconductor devices.
To be able to design simple converters for practical applications.

Learning outcomes
On completion of this module students should be able to:

1. To understand the principles of power control by switching; demonstrate the benefits of switched mode circuits; familiarise with the commonly used semiconductor switching devices;
2. To demonstrate a full understanding on several DC-DC converters; perform analysis on their operation principles; develop design equations for selecting their components;
3. To be able to explain how the steady-state AC voltage and current are related to each other in power circuits using phasor analysis;
4. To understand and be able to quantify active, reactive and apparent power;
5. To comprehend the operation principles for several thyristors based rectifiers; quantify the current harmonics and the average power drawn by a rectifier;
6. To understand the H-bridge based inverters and their several control methods; develop the skills in analysing the different modes of operations for the inverters; gain the understanding on how the power is delivered or absorbed by grid-connected inverters.
