Research Interestspower electronics: control/switching strategies and topologies for power converters in renewable energy systems; voltage and harmonic compensation; active filters; power quality; high-frequency power supplies
I completed my undergraduate degree in electrical engineering at the University of Science and Technology, Kumasi, Ghana and attended the University of Toronto where I obtained the M.Sc. and PhD degrees in electrical engineering in the area of power electronics. Following a one-year post-doctoral position at the University of Toronto, I joined Memorial University of Newfoundland in September 1982. I was the chair of the electrical engineering discipline from 1990 to 1999, associate dean of undergraduate studies from Sept. 2002 to Aug. 2008 and dean pro tempore from September 2008 to June 2011.
My undergraduate teaching activities are in the areas of electric circuit analysis, electronic circuit analysis and design, power electronics and energy systems. I also teach graduate courses in the area of power electronic systems, including modeling, analysis, control and design of power converters for various applications.
My current research activities focus on the development of control/switching strategies and topologies for renewable energy systems, including fuel-cell, wind energy, and tidal energy generation systems. My research is carried out with undergraduate and graduate students in an atmosphere that encourages continuous interactions among the group members and fosters the development of innovative techniques and generation of new ideas.

The focus of my research for a number of years has been the development of alternative control strategies for inverters in uninterruptible power supply and utility interface applications. A major contribution of the work was the successful development of a novel multi-loop, current controlled voltage regulated PWM scheme for dc-ac voltage source inverters, derived from small-signal models of the controllers, the output low-pass filter and the power converter. The work on the control scheme was one of the first systematic approaches to deriving a unified model of the controller and the power converter. It resulted in a number of publications, including an IEEE Transaction publication, which has made a significant contribution to the control of inverters and influenced research activities in inverter control.
