The more-electric revolution is transforming the way that non-propulsive power is generated, distributed and used on-board an aircraft, whilst more radical future concepts anticipate partial or full electric propulsion.

These innovations promise significant reductions in emissions, but require highly efficient, light-weight generators, motors, power converters and electrical systems. These system will be highly dynamic with peak powers of several MW, requiring techniques for the overall system control / management, including energy storage. 

Research focus

  • Hybrid energy storage systems
  • Super-conducting machines, converters and systems
  • Platform level power management and protection
  • Advanced generator control
  • DC bus power quality and stability
  • Emulation of mechanical prime movers

Key applications

  • More-electric aircraft
  • Electric and hybrid vehicles
  • Marine / ship power networks
  • DC smart grids

Collaboration with industry

The Group has several active grants on electrical system integration in collaboration with Rolls-Royce through the Rolls-Royce UTC, including the EPSRC project Analysis of Power Quality in Complex DC Power Networks. The Group is also involved in the EPSRC-funded Vehicle Electrical Systems Integration (VESI) project.
