  • Analysis for maximum energy transfer from existing DC-to-DC converter topologies. 
    Nagahapitiya, N. W. H. G. B.; Jayatissa, N. W. K. (International Research Symposium on Pure and Applied Sciences, 2017 Faculty of Science, University of Kelaniya, Sri Lanka., 2017)
    A voltage regulator is an electronic device, which maintains a constant output voltage for varying input voltages. There are different types of voltage regulators with various types of control schemes to achieve great ...
  • Design and performance investigation of a canonical circuit model for power converters 
    Sandanayake, P. S. D.; Jayatissa, N. W. K. (Research Symposium on Pure and Applied Sciences, 2018 Faculty of Science, University of Kelaniya, Sri Lanka, 2018)
    A “Switched Mode Power Supply (SMPS)” is an electronic device that involves switching regulation for efficient power conversion. They take power from an AC or a DC input, and produce a processed current/voltage output of ...
  • Improving the response time of an ultrasonic wind speed measuring system using a temperature measurement 
    Pieris, T. P. D.; Jayatissa, N. W. K. (Research Symposium on Pure and Applied Sciences, 2018 Faculty of Science, University of Kelaniya, Sri Lanka, 2018)
    Natural wind in the open air is a three-dimensional vector but vertical component of the wind is ignored in the most meteorological operations. Therefore, the surface wind is considered as a two-dimensional vector in this ...
  • Smart White Cane. 
    Kaushalya, K. W. A.; Fernando, A. P. N.; Ekanayake, H. M. P. K.; Jayatissa, N. W. K. (In: Proceedings of the International Postgraduate Research Conference 2017 (IPRC – 2017), Faculty of Graduate Studies, University of Kelaniya, Sri Lanka., 2017)
    Blindness or visual impairment affects many people around the world. There are nearly 14 % visual disables in Sri Lanka. Blind people use white canes to identify obstacles by moving the cane. Over the years, blind people ...
  • Thermal desalination process - Design perspectives. 
    Jayatissa, N. W. K. (International Research Symposium on Pure and Applied Sciences, 2017 Faculty of Science, University of Kelaniya, Sri Lanka., 2017)
    Urban areas, although better served than rural areas, are struggling to keep up with the population growth. Population increase on Earth, is directly related to the global food and energy demand. Expansion of the agricultural ...
