One of the bottlenecks limiting the development of electric vehicles and more-electric-aircraft is the size and weight of the power electronic equipment that is needed to convert electrical energy between different voltage levels, for example between a battery or fuel cell and the traction system.
The Power Conversion Group is devising new power-dense converter topologies using the latest power electronic devices, advanced magnetic materials and high-speed control. Funding sources include the EPSRC Centre for Power Electronics, the EPSRC PowerGaN Programme Grant and industrial collaboratorsRolls-Royce plc and Lyra Electronics.
