Academic and Professional Background[edit | edit source]
I have completed BSc (Hons) Degree in Electrical and Electronic Engineering at Sri Lanka Institute of Information Technology in 2020. I am currently working as an Assistant Engineer in Rannara Engineering. I perform tasks related to harmonic tests for solar systems, design specifications for solar dehydrators, handling solar projects and handling automation systems. I'm highly interested in pursuing my graduate study and research in the areas of solar photovoltaic technology, solar-powered open-source 3-D printing and power systems control.
In my undergraduate research project, we designed a wireless power transfer device for cardiac pacemaker.

Wireless Power Transfer for Cardiac Pacemaker[edit | edit source]
Cardiac pacemaker is an electronic device used to regulate the heartbeat of patients suffering from congenital heart defects. Considering the limitations in the lifespan of current cardiac pacemaker battery, a wireless charging mechanism for the cardiac pacemaker is proposed in this work. The circuitry model and electromagnetic geometry is developed using Ansys Maxwell and Ansys High-Frequency Structure Simulator (HFSS) software to analyze three main technical issues such as implantation, efficiency and safety. Specific Absorption Rate (SAR) and induced electric field in a 3-D model human body is evaluated by numerical analysis and simulation to ensure that the developed system adheres to safety limits proposed by the Institute of Electrical and Electronics Engineers (IEEE) standard and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines.

Undergraduate Projects[edit | edit source]
IoT based smart energy meter for houses [3rd year project][edit | edit source]
Nowadays, people are wasting more electricity which results in energy wastage and increases in monthly electricity bills. In addition, the lifetime of electrical appliances reduces due to over usage. Hence, it is required to replace the appliances frequently which result in high cost and an increase in environmental pollution,
Therefore, to reduce energy waste, a smart energy meter is proposed in this work. It is designed to measure the power consumption of a household and provide a billing system through a mobile app so that the user will be aware of their upcoming monthly electricity bill. The smart energy meter is also designed to evaluate the power consumption in each room. Hence, the user can monitor the energy consumption in each room of the household and try to minimize it. This will result in the reduction of electricity bill as well as saves electric energy. Compared to the current smart meters available in the market which output live results, the smart energy meter proposed in this project is designed to collect and analyze energy consumption with the goal of reducing energy wastage.
Mini solar power plant [1st year design project][edit | edit source]
The mini solar panel power plant is designed to harness solar energy by rotating the solar panel for 180 degrees to charge a 12VDC battery. A motor is fixed to the rotating solar panel and controlled by Atmega 328 microcontroller. The micro controller is programmed to rotate the solar panel from one horizon to other in order to find the position where maximum amount of solar energy could be absorbed.
