- Profile
-
I studied Electronic Engineering at the University of Sheffield from 1982 - 1985, and graduated with a 1st class BEng (Hons) before moving to Liverpool University to study my PhD.
I graduated from Liverpool University in 1989 with a PhD in Automatic Weld Penetration Control, having developed a vision system and power electronics capable of controlling the penetration of a TIG welding arc through the workpiece.
After graduating with a PhD, I joined the University of Sheffield as a member of academic staff in the Electrical Machines and Drives (EMD) Group where I have been working to date, having been promoted to Professor in 2013.
My research interests include Power electronics and Energy storage, and currently, through CREESA, we operate the largest grid connected lithium titanate electrical energy storage system in the UK.
- Research interests
-
- Simulation and modelling of energy generation and storage, including Hybrid energy storage systems - combinations of flywheels & different battery technologies for optimal storage
- Modelling of energy systems related to transport systems, including trams systems, freight vehicles, public transport system and private vehicles
- Development of ‘smart’ battery packs for all-electric and hybrid-electric vehicles, based on both Li-based chemistries, Ni-MH and VRLA cells containing cell state-of-charge monitoring and conditioning electronics to extend the lifetime of the cells. Incorporation of observer techniques into state of function monitoring for cells to increase operation lifetime and consumer confidence in battery technology
- Investigation into second life operation of EV batteries for Grid support and localised energy storage
- High efficiency EV-contact less battery charging
- Investigation into high frequency, high power, resonant converters for induction heating applications. Continuing work is now looking at the use of high frequency matrix converters (operating above 150kHz) for direct ac-ac conversion for heating applications
- High voltage power supplies
