Analysis of Impedance Matching Technique for Novel Supercapacitor Assisted PV Systems

Piyumal, P.L.A.K.; Ranaweera, A.L.A.K.; Kalingamudali, S.R.D.; Kularatna, N. (IEEE Computer Society, 2020-10)

To extract the maximum power from a photovoltaic (PV) system, the maximum power point (MPP) of the PV array must be tracked continuously. A directly coupled load with the PV array does not track the MPP of the PV array ...
Designing and constructing a DC microgrid with uninterrupted power supply capability and optimizing its energy usage by smart controlling system

De Zoysa, H.B.H.; Guruge, P.A; Kalingamudali, S.R.D; Kularatna, N.; Kanishka, G. (2018 IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES), 2018)

Abstract: This paper outlines the methodology of designing and implementation of a solar powered system which can be used to make a human comfort zone during day time without using battery backup but with the use of ...
Improving the Energy Storage of Standalone PV Systems while Enhancing the Charging Efficiency using Supercapacitors

Piyumal, P.L.A.K.; Ranaweera, A.L.A.K.; Kalingamudali, S.R.D.; Kularatna, N. (IEEE Xplore Digital Library, 2019)

Usually a battery is used as the energy storage device in typical standalone solar photovoltaic (PV) systems. It is charged by a solar charge controller. The charging efficiency of the system depends on the efficiency ...
Maximum Power Point Tracking of an Off-grid Photovoltaic System Consisting of a Series Connected Supercapacitor with a Step-down Converter

Piyumal, P. L. A. K.; Ranaweera, A. L. A. K.; Kalingamudali, S. R. D.; Kularatna, N. (The Electrochemical Society, 2022)

An off-grid photovoltaic (PV) system's PV array is connected with a charge controller as the first power conversion stage. The average efficiency of the power stage of charge controllers is around 90%. Supercapacitor ...
Novel Approach for Harnessing Maximum Energy from PV Systems using Supercapacitors

Piyumal, P.L.A.K.; Ranaweera, A.L.A.K.; Kalingamudali, S.R.D.; Kularatna, N. (IEEE Xplore, 2018)

Typical standalone solar photovoltaic (PV) systems use battery bank as the energy storage device. The battery bank is charged by using a solar charge controller connected to a solar array. For similar PV systems, charging ...
Supercapacitor Assisted Hybrid PV System for Efficient Solar Energy Harnessing

Piyumal, K.; Ranaweera, A.; Kalingamudali, S.; Kularatna, N. (Electronics 2021, 2021)

In photovoltaic (PV) systems, maximum power point (MPP) is tracked by matching the load impedance to the internal impedance of the PV array by adjusting the duty cycle of the associated DC-DC converter. Scientists are ...
