| DESCRIPTION | - Multilevel Converters Multilevel converter configurations and their method of control and switching will be discussed. Their main advantages are smoother power delivery, greater power processing for a given size component, and modularity. High voltage and high power applications, with components such as fuel cells, solar arrays, and electric and hybrid vehicles will be discussed. - Matrix Converters This novel type of converter was developed to convert an a.c. source directly to another a.c. source of varying frequency and amplitude without the need to a d.c. link in between. The construction and control of these converters will be explained. - Grid Connected systems (p.v. and wind) and Distributed Generation The power electronic converters used in the grid connection of wind and p.v. systems will be discussed. PM synchronous generators and DFIM with back to back converters will be covered in detail. The construction and control of grid-connected inverters will also be considered and techniques to detect for 'islanding' will be discussed. Finally the basic concepts of how to operate and control a DG or 'smart' grid system shall be introduced. -Engineering Applications of Power Converters Various applications such as High Power Factor topologies, Active Filters, HVDC, Energy Storage. Objectives: This study-unit will lead to an understanding of advanced power converters used for energy conversion. Direct ac to ac conversion and dc to high voltage ac conversion will be covered in detail. Connection of renewable energy sources to the power transmission grid will be discussed with an international perspective. Study-unit Aims: The aims of the study-unit are to present the electrical engineering student with knowledge in the areas of advanced power converter topologies used for energy conversion. Direct ac to ac conversion and dc to high voltage ac conversion will be covered in detail. Connection of renewable energy sources to the power transmission grid will be discussed with an international perspective. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - identify various power electronic topologies (e.g. multilevel, matrix, grid-connected inverters and high power factor topologies). - implement control for the above mentioned topologies. 2. Skills: By the end of the study-unit the student will be able to: - Analyse circuit behaviour of power electronic topologies covered in this unit. - Perform design calculations to size appropriately specific components of these power electronic circuits. - Select suitably rated components for the implementation of power electronic circuits considered.
