|Title:||Modified MISO DC-DC converter based PV water pumping system|
Multi-input single-output (MISO) converter
|Abstract:||In this paper an modified MISO DC-DC converter based Photovoltaic (PV) water pumping system is designed for population living in remote areas to fulfill their water pumping requirement for various applications like drinking water, water for irrigation and daily needs etc. With the objective of improvement in performance and efficiency of PV based water pumping system and thus to justify its installation cost, a modified Multi-input single-output (MISO) converter is proposed. Contribution of this paper is the implementation of proposed MISO converter to the conventional PV based water pumping system to enhance extraction of power from PV units under partial shading/mismatching phenomena without any energy storage device. Various irradiation patterns are considered to create the mismatching conditions and observe the performance of designed system. To verify the performance of proposed MISO converter, designed system is simulated in MATLAB/SIMULINK environment. Simulation results show that the implementation of proposed MISO converter instead of conventional DC-DC converter based PV water pumping system increases the extracted power from PV units under mismatching phenomena. � 2016 IEEE.|
