Analysis and study of Zeta converter fed by solar photovoltaic array

摘要

Due to the increasing demand of electricity and the limited conventional energy resources, Solar Photovoltaic energy becomes a favorable alternative as it is pollution free, freely available and has less maintenance cost. This paper presents basic steady state analysis of Zeta Converter by using State Space Averaging Method in continuous inductor current mode. The Zeta converter is a fourth order DC-DC converter which is capable of operating in Buck and Boost Mode. The Zeta Converter is cascaded between Solar Photovoltaic Panel and Load. The input voltage to Zeta converter is fed by a photovoltaic panel. The modeling of solar panel is done by considering the design equation of photon current and reverses saturation current. The objective of this paper is to analyze the performance of Zeta converter by a change in Temperature, Irradiance, Duty Cycle and Load Resistance. The effectiveness of model with the result is verified by using simulation done in MATLAB™ Simulink.
