The photovoltaic system is generally intermittent in nature because of instability in weather such as irradiance and temperature. Therefore it is critical to stabilize the output voltage when a PV module supplies power to wide range of loads. In order to address this issue, boost converter under variable irradiance (300-8000W/m2) has been used to extract maximum power from photovoltaic panels applying the conventional Perturb and Observe algorithm in this paper. The unregulated boost converter output considered as input to a buck converter which is controlled by a Proportional Integral controller in order to stabilize the output voltage for different resistive loads. It has been shown that the controller has been successfully capable of regulating the output voltage for wide variation of loads and varying irradiance. The integrated system is bulit and analyzed in MATLAB/Simulink environment.
