Research

My research began from dynamic modelling for linear induction motors (LIM), and industrial applications. My current research spans both the theory and applications of magnetic materials for future energy systems, e.g. electric vehicles and renewable energy systems. My major research interests are new magnetic materials for modern electrical machines, static and dynamic modelling of magnetic materials under complex magnetisation conditions, condition monitoring of magnetic cores of power transformers and rotating machines, and optimised design of linear motors for industrial applications. In this respect notable projects include, development of novel techniques for condition monitoring of magnetic cores, static and dynamic hysteresis modelling of magnetic materials for high frequency applications. These activities are approached from the phenomenological concepts of magnetic hysteresis and energy loss mechanism of magnetic materials.

I also have interests in reactive power control in renewable energy systems, dynamic modelling of grid connected renewable energy systems, high frequency and transient response analysis of grounding systems, and dynamic modelling of grounding systems for HVAC and HVDC systems under transient fault conditions.

I have published over 20 journal papers and 35 peer reviewed conference papers, and regularly present my work at international conferences.
