Advanced Power Electronic Converters and Devices

(15 Credits)

Aims:

Practically all electronic equipment, whether domestic or industrial, requires power conditioning to deliver the energy for it to operate correctly. This is using electronics for power processing, not information processing. The applications vary widely from power supplies for laptops and mobile phone chargers, through industrial motor drives, hybrid and electric vehicle drives, electric rail transport, to solar and wind energy systems and power transmission and distribution systems. With the foundation of studying the module ES3E0 Power Electronics, ES4E8 is to give students a wide range, in-depth and advanced knowledge of Power Electronics and Devices.

The module aims are:
• To introduce the advanced power electronics as power processing and control, and to present the power electronics converters used for switch-mode power supplies, connection of renewable energy to the power grid and electrification of transportation.
• To introduce advanced power semiconductor device design concepts for industry-ready power electronic converter components, and describe the theory of their operation.
• Advanced packaging and reliability considerations for power electronic converters, taking into account thermal and switching budgets.
• To introduce emerging and future power semiconductor devices utilising new materials such as silicon carbide and gallium nitride.
• To introduce power electronic converters/inverters and control for various applications and give design examples of applications.
• To develop an understanding of the issues of power quality and EMC present in converter and device design.

Learning Outcomes:

At completion, students will be able to:
• Understand the operation and conceptual design principles for current source converter and voltage source converter.
• Systematically analyse and design multilevel power electronic converters including Neutral-point-clamped configuration, Flying capacitor configuration, cascade configuration and modular multilevel converters.
• Design advanced power converters for different applications.
• Practically conduct power quality, harmonic and EMC analysis in converter design.
• Apply advanced concepts through the use of device physics in the context of device design (forward, reverse characteristics and switching) for use within a power converter.
• Design a power semiconductor device for a specific application with the aid of a finite element simulation package.
• Conduct complex packaging and reliability analysis of power semiconductor devices.
• Analyse systematically new materials for power semiconductor devices; silicon carbide and gallium nitride.
