Unit Description and General Aims

This course will introduce you to the principles and practice of smart electrical energy conversion. The fundamental power electronic converter topologies are introduced, and you will learn about modulation processes (i.e. switching) and control techniques for these systems. Topics that are covered in this course include: elementary switching cells, diode rectifiers, thyristor rectifiers, DC/DC buck and boost converters, two-level DC/AC converters, three-level DC/AC converters. Moreover, the procedure for designing various controllers (closed loop DC and AC current regulation, linear regulators, non-linear hysteresis regulators) for such converters will be discussed. Finally, several real-world applications such as grid-tied power converters for renewable energy grid integration, variable speed drives, and UPS systems are presented as examples. The fundamentals presented in this course will assist you in range of further studies, including Variable Speed Drives, Switched Mode Power Supplies, Renewable Electrical Energy Systems, Power Electronic Converters, etc.
