This includes multinational microelectronics giants, EDA start-ups, and world leading laboratories such as IMEC, where the group's students have three to nine month placements. All students have access to Europractice CAD tool training and chip fabrication facilities.Power electronics, drives and machinesThe group's activity is principally directed in the renewable energy, aerospace, automotive and consumer product sectors.Ê All aspects of power electronics and drive systems are covered including:
- stand-alone and grid-connected converters for renewable generation
- fault-tolerant machines and drives
- ultra high-speed machines/low cost drives
- exploitation of insulated, compacted iron-powder for novel and improved performance machines
- novel power converter topologies and thermal management
- novel energy storage systems
- sensors and drive controllers for safety-critical applications
- power semiconductors
- drive configurations
- advanced nonlinear modelling, control and optimisation strategies and applications
The group is recognised as one of the leading European research groups in this sector, working in areas from 'blue sky' research to product applications. Projects may involve one or more of the following themes: electrical machines, power electronics or control engineering.
