This PhD project will propose new topologies and control strategies for high-speed machines and active magnetic bearing drives targeting sustainable and cost-effective aerospace propulsion. The main aim of this project is to develop techniques for power electronics control and high-speed sensing for Active Magnetic Bearing drives considering the use of wide bandgap power semiconductor devices. The project will be closely linked with NEMA's high speed motor/generator control and active magnetic bearings development. Innovative functional integration between different components of the drive converter will enable a cost-effective and compact solution.
