EFFICIENT INTERLEAVED BUCK BOOST CONVERTER FOR SOLAR APPLICATIONS

Abstract

Solar Energy is the prominent source of renewable energy. But, the practical DC –DC converter can extract only partial amount of energy from the Solar cells by our conventional methods. An interleaved buck boost dc/dc converter is developed that it requires only a smaller input/output filters, it provides the fast dynamic response and low stress on the devices than conventional designs, for solar powered applications. Input and output ripples of voltage and current of the converter is very low. The simulations were carried out using MATLAB/SIMULINK software package and hardware implemented.
