Abstract: Solar systems are becoming increasingly prevalent in distribution and generating system. This is because of its large availability. Even though there is a large availability, it is not commonly used because large area with huge installation cost as well as maintenance cost is required. One of the major field in which solar energy used is water pumping for small scale irrigation. This paper is aimed to introduce Cuk converter as well as impedance source inverter in pumping system along with photovoltaic cells (PV) in order to obtain a constant power output irrespective of the intensity of solar radiation with low installation and maintenance cost.The proposed model is developed with the help of MATLAB/Simulink.
Keywords: Cuk converter, PWM Technology, impedance source inverter, VFD technology.
