Description

The aim of this unit is to understand the requirements of modern power networks in terms of energy conversion through power electronics and machines and demonstrate the benefit of full system integration.

This unit covers the requirements of modern power networks in terms of energy conversion through power electronics and machines. It discusses the basics of power semiconductor devices, converter topologies ranging from the switched-mode power supplies to MW-rated power converters in transmission systems, analysis of power systems and the synchronous machines that connect to these systems.

The unit will use a range of end-to-end case studies to allow students to experience first-hand and explore the design considerations and trade-offs that engineers must balance when prototyping innovative, efficient and integrated solutions to real-world problems.

Intended learning outcomes

Upon successful completion of the units students will be able to:

  1. Describe the fundamental elements (and their roles) of an electric drive system
  2. Explain the basic operation of power semiconductor devices as a switch and the role of diodes in providing current flow and commutation paths
  3. Implement and appraise, using appropriate modelling techniques over a range of applications and scale
  4. Calculate how power flow is managed in a multi-phase energy system, including stability under transient conditions and fault and unbalanced conditions
  5. Design and evaluate a full end-to-end electric drive using appropriate topologies for the various elements of the system
  6. Explore the impact of electro-mechanical drive integration at the system (application) level

Teaching details

Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, activities supported by self-directed exercises and by problem sheets.
