Department of Electronic and Electrical Engineering
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.

Qualifications
  • PhD, University of Liverpool
  • BEng, University of Sheffield
  • FIET
Research interests
  • 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
  • Modelling and control of novel fluorescent lamps to improve the efficiency of light generation. Incorporation of physical lamp models (based on electron energy level interactions) into both Simulink and spice based packages has led to novel lamp models based on the physical interactions within the plasma
  • Design, modelling and digital control of high-order resonant converter topologies for high frequency switched mode power supplies for use in ‘white goods’, and concentrates on the analysis and design of high order resonant converter topologies, with the inclusion of piezzo electric transformers where possible
  • 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
  • Design and digital control of matrix converters for aerospace and sub-sea applications in specialist environments
  • Power Electronics Packaging for high temperature and harsh environments, including high temperature gate drive design and thermal management of converters
  • High voltage power supplies
  • Grid connected energy storage first and second life battery packs on the grid for grid support
  • Hybrid energy storage systems - combinations of flywheels & batteries for optimal storage
