Phil Mellor“The Bristol Electrical Energy Management Research Group investigates advanced energy conversion for low-carbon electrical systems that require optimised efficiency, and high power or energy density. Our well-equipped laboratories include high-power test cells, state-of-the-art measurement capabilities for advanced power electronics, and rapid manufacturing facilities.

Prof. Phil Mellor, Head of Group.


The Energy Management Group undertakes research into low carbon electrical systems that are enabled by advanced, compact and highly efficient electrical machines and power electronic conversion. The management of electrical power is the core challenge, with a focus on the systems employed in aircraft, automotive drive systems, renewable energy plant and micro-grids. The group is a core member of the UK Centre for Power Electronics, and a Competence Centre of the European Centre for Power Electronics (ECPE). The group has around 40 researchers, with specific expertise in:

  • High-performance, mission-optimised electrical machine design synthesis.
  • Supporting technologies for GaN and SiC power devices: novel gate drivers, switching-aid circuits, new circuit topologies, control methods, sensors.
  • Ultra-low loss (<1%) mains-rated converter development using superjunction devices.
  • Multi-level converters for wind power, advanced topologies, control and testing.
  • High-performance passive component design: multi-physics design optimisation, thermal and loss analyses, new mixed-material structures, novel integrated magnetic components.
  • Power electronic systems for the managing of energy at sub Watt levels for use in energy harvesting and HV supplies; novel circuit topologies, exploitation of non-linear behaviour.
  • Coupled electromagnetic/thermal/electrical system modelling, multi-objective optimisation, accurate reduced order/functional modelling of power electronic system elements.
  • Robust minimal sensor control methods, design for fault tolerance.
  • Wireless power transfer for moving targets (RF and inductive).
  • Integrated magnetics.
  • High-efficiency and high fidelity amplifier design.
