His research interests include:

 

  • Power Electronics
  • Electrical Machine Drives
  • Renewable Energy
  • Electric Vehicle, Traction and Propulsion

Areas of research expertise include power electronics and machine drives in the renewable energy, aerospace and automotive sectors. I have consulted for many global industrial companies in the UK, USA, China, Europe and Japan. I highlight the main research grants that I have held in the last 5 years which indicate the range of research I have conducted recently.

Electrical Machines and Drives:

ARC Discovery Project $380k              2013-2015                         CI3

Dynamic model and mechanical sensorless controller for a novel concentrated-winding interior permanent magnet machine for electric vehicles (DP130103760)

The FSCW IPM machine offers very high power density, efficiency and constant-power speed range; properties that are sought for electric vehicles. Its high performance control, which requires an accurate mathematical model, is still not available. This project seeks to develop this model and the sensorless controller for the FSCW IPM machine. The research work is undertaken collaboratively with CSIRO.

Proof of Concept          £195k                         CI1

Improved electrical generation systems for renewable energy and micro-generation (9-ENR-001) I contributed to the research and development of five-phase permanent magnet generator technology and manage the efforts of a team which includes 1 Research Fellow, 2 Technology Entrepreneurs, and 1 a Commercialisation Officer from RKES. The technology is in the process of achieving a commercial outcome through spin-out and licensing opportunities.

Renewable Energy:

Engineering and Physical Sciences Research Council          £523k                         CI1

Multi-terminal dc transmission micro-grid system for interfacing multiple wind turbines (DT/F006381/1)

I managed and contributed to the research effort of three PhD students and 1 senior Research Fellow on a £1.5M collaborative research and development project with Proven Energy and Scottish and Southern Energy.  The aim of the research is to develop a novel current-fed multi-terminal DC link system for the capture of energy generated by wind turbines.

SEEKIT RENEW-NET   £800k                         CI1

Renewable Energy Electrical System Technology Transfer Network – RENEW-NET

I supervised 1 Research Fellow at Strathclyde and contributed to the management of the collaborative project which includes 7 other researchers and staff. The project was to develop a Technology Transfer network in the renewable area to assist small and medium sized enterprises access knowledge and expertise in the university sector. The project assisted over 30 local companies developing new technologies in the sector and levered in excess of £2M in research grants and associated support mechanisms.

Engineering and Physical Sciences Research Council          £800k                         CI of 8

Techniques for Electric Power Systems with High Penetrations of Non-Thermal Generation (EP/G013616/1)

I was one of eight members of the research team managing this EPSRC project. The team facilitates new and emerging research themes, identifies funding opportunities, and approves the allocation of EPSRC funds for pilot projects. The projects enabled research fellows to dedicate time and resource to new and novel ideas in the generation sector.

ETI                                                                  

‘Nova’ and ‘Helmwind’ Consortium Projects

I contributed to the power electronics and drives research theme in this multi-partner collaboration which has 2 Research Fellows employed at the University of Strathclyde. The two projects aim to develop novel wind turbine technologies for offshore wind applications.

Engineering and Physical Sciences Research Council          £6.5M             

Doctoral Training Centre in Wind Energy Systems

I contributed to the delivery of a new Masters by Research programme to the 11 PhD students in the Doctoral Training Centre on Wind Energy Systems. The Doctoral Training Centre will support 50 PhD scholarships in the wind energy sector over the next 9 years.

Power Electronics:

Engineering and Physical Sciences Research Council          £330k                         CI1

High-temperature Silicon Carbide Electronics – HITSIC (TS/G000417/1)

I managed and contributed to the research effort of 1 senior Research Fellow on a £1.6M collaborative research and development project with Raytheon Systems. The research project developed a CMOS process for Silicon-Carbide that can operate at high temperatures.  

AWE                            £150k                         CI1

Modular MOSFET and IGBT pulsed-power systems

I supervised a PhD student on a project funded by the Atomic Weapons Establishment to develop power electronic-based pulsed-power systems for the next generation of X-ray generators liaise with applications in X-ray diagnostics and emerging medical applications.

Engineering and Physical Sciences Research Council          £173k                         CI3

High Voltage Igbt Series Connection (GR/R19762/01)

This project developed active gate drive control for the series connection of power IGBTs. The technology enables multiple power devices to series connected together such that their voltages share instantaneously at all times including during rapid turn-on and turn-off.

Engineering and Physical Sciences Research Council          £4.2M             

SUPERGEN HDPS Core Consortium (EP/G031681/1)

I contributed to the power electronics research theme in this multi-partner collaboration. The consortium includes 22 other university investigators.
