Curricular information is subject to change
On completion of this module students should;
• Have gained an advanced knowledge and understanding of the role which DC-DC converters play in powering electronic systems and a knowledge of the technologies which underpin such converters.
• Be able to identify and distinguish between different power converter circuit topologies, formulate the circuit equations which describe their operation and hence analyse their operation.
• Be able to perform detailed design of a DC-DC converter to meet a given specification including the design of the circuit, its closed loop controller, and the design or make appropriate selection of the components from which it is built.
• Be able to simulate using advanced circuit simulation, build and test a prototype DC-DC converter circuit including the ability to conduct experiments to analyse its performance.
• Gain an understanding of the importance of engineering standards and their relevance to aspects of dc-dc converter design.
• Effectively communicate their design approach and choices through written technical reports on the laboratory work.
The module is divided in to three major sections with content as follows:
1) Converter Circuits: A range of commonly used non-isolated and isolated DC-DC converter circuits are analysed including Buck, Forward, Half Bridge, Full Bridge, Boost, Buck-Boost and Flyback circuits. Analysis focuses on circuit operation and analysis of losses. A range of application focused design examples are provided. Active Power Factor Correction is also covered.
2) Closed loop control of DC-DC converters: This includes the derivation of small signal linear models for DC-DC converters and the design of analogue based controllers to ensure stability. Voltage mode and current mode control are covered. Numerous desing examples are provided.
3)Components: This sections covers the choice of converter components such as capacitors, inductors, diodes and switches. Design of inductors and transformers is also covered.

• Feedback individually to students, post-assessment
• Group/class feedback, post-assessment
Feedback on lab reports is provided by means of a grade and a breakdown of the grading approach. More detailed individual feedback will be provided by the module coordinator on request. General feedback to the entire class is provided after grading of the first set of lab reports to indicate common areas for improvement. Feedback on the continuous assessment assignments will be provided by means of an overall grade and a breakdown of the grading for various sections of the assignment.
