Comparison Study of Buck-Boost and Zeta Converter for Real Time Application

DC-DC power converters are the intermediate stage of conversion between photovoltaic input and output. The need for a DC-DC converter is quite significant in obtaining maximum power from a photovoltaic array. In this paper, a detailed analysis is implemented to analyze the use of a converter as MPPT with Perturb and Observe (P&O) algorithm for low-power applications such as e-bike battery. and realized with real-time data. Buck-boost and Zeta converters are considered for analysis and its basic mathematical modeling and simulation using MATLAB/SIMULINK is carried out for real- time data. And it is inferred that the zeta converter is suitable to choose when compared to buck-boost converter.
