Electrical and Electronics Research Group

The Electrical and Electronics Research Group has expertise in electrical insulation and dielectric phenomena, a wide range of electronic systems, power electronics, novel electrical machines, and electrical propulsion. Work ranges from fundamental research to industrial consultancy.

Described below are the principal research areas, the facilities and the staff in the research group.

Electrical Insulation and Dielectric Phenomena

Research in the "High Voltage Lab" at Leicester is on electrical insulation and dielectrics - materials that respond (either in a useful or detrimental way) to electric fields. The main applications are in high voltage or high field systems, such as polymeric power cables and transformer bushings, capacitors and printed circuit boards.

Electronics, Machines, Propulsion Systems and Renewable Energy

Research in the Electronics, Machines, Propulsion Systems and Renewable Energy Labs is related to many aspects of practical electronics, including the generation and utilisation of electrical power. The Group has an established reputation in electrical and hybrid propulsion, including the development of electric racing engines. A common factor in the research is the increasing use of power electronics and micro-controllers for the efficient conversion of electrical power, such as in spacecraft power supplies. Extensive facilities are available for simulation, design, prototyping and experimental verification of new circuits, machines and systems. Practical electronics expertise is also a key area of industry engagement and consultancy.

Facilities

Following a £1M refurbishment, the Group is now accommodated in a large laboratory suite, comprising three dedicated laboratories.  There are a wide range of laboratory resources and specialist equipment including:

  • High voltage testing equipment up to 400kV DC, 80kV AC 50Hz
  • Broadband dielectric spectroscopy (mHz to MHz)
  • Space charge measurement using pulsed electroacoustic (PEA) techniques
  • High sensitivty electrical treeing and electroluminescence equipment with application in electrical treeing detection and partial discharge interpretation
  • Equipment for the development of electronically controlled drives and generators
  • 50 kVAp PV array
  • Equipment for the development embedded generation systems, including: photovoltaic, wind power and variable speed generation and a large scale wind turbine simulator
  • Electrostatic and magnetodynamic modelling and CAD facilities
  • Large and small electrical machines and drives test facility with a 200kVA 3 phase supply
  • 3000 amp pulsed power generator
  • large battery charge/discharge unit designed for fork-lift truck and submarine batteries.

The group has access to a wide range of other facilities around the University including those of the Advanced Microscopy Centre, and engine and propulsion test facilities.
