Electrical Energy Management Research Group

RF engineering for high frequency power switching, and wireless power transfer.


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’s facilities include: Joint design and manufacturing of machines, drives, and power electronic converters. High-fidelity AC/AC power conversion equipment for the optimisation of drive efficiency. 200 kVA and 1 MVA dynamic testing, and hardware-in-the-loop simulation. Large pool of high-end test equipment, and advanced design and validation software.

Phil MellorThe 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.
