Personal profile

Biography

Dr. Neo Lophitis is a Senior Lecturer at the School of Computing, Electronics and Mathematics, Coventry University. Also, he is an associate with the Research Institte for Future Transport and Cities, Coventry University, and an Academic Collaborator with the High Voltage Microelectronics and Sensors Group, University of Cambridge. 

Neo received the Bachelor of Arts with Honours (BA Hons) in Electrical and Information Science (2008), the Master of Engineering (MEng) in Electrical and Electronic Engineering (2009) and the PhD in Power (2014) from the University of Cambridge, Cambridge, UK.

His research includes addressing issues associated with the functionality, efficient performance and reliability of power and photovoltaic semiconductor devices by means of modelling, simulation, design, fabrication and evaluation of novel concepts both in Silicon and wide bandgap materials such as Silicon Carbide and Gallium Nitride.

Active Projects

Underpinning Power Electronics (UPE) 2: Switch Optimisation Theme  (EP/R00448X/1)

Dr. Neo Lophitis is participating in one of the Engineering and Physical Sciences Research Council’s (EPSRC) five flagship Underpinning Power Electronics (UPE) projects. Each of the three-year £1.2-£1.4 million projects focuses on a different aspect of the power electronics supply chain with the aim of creating new devices and applications to fully realise the energy saving potential of this emerging technology.

Partnering Cambridge, Newcastle and Warwick on the ‘switch optimisation’ theme, we will be developing ultrahigh voltage silicon carbide (SiC) n-IGBTs. With voltage ratings over 10 kV, nearly 10 times the voltage rating of any SiC device on the open market, SiC insulated-gate bipolar transistors (IGBTs) have the potential to make considerable gains in efficiency for the National grid, e.g. when connecting off-shore wind power to the network. 

Open Research Positions

PhD in Reliable power conversion through condition monitoring of power semiconductors and electronics

Power Electronics Converters are exceptionally important in systems that operate in changeable, isolated, challenging environments or where the degradation of operation can potentially be life threatening. Practical examples of scenarios which would benefit from the integration of Condition Monitoring include; offshore wind turbines, aerospace power supplies, traction drives and electric vehicles.

MRes in Reliable and compact high performance power electronics in electric and hybrid vehicles through power semiconductor engineering

Master in power semiconductor engineering for the development of high performance and reliable power semiconductor devices. The focus of the project will be to design devices that mitigate from issues that cause reliability problems and fully exploit the advanced characteristics of wide band gap semiconductors.
