Comparative Study Of High Step-Up DC-DC Converters For Photo-Voltaic Module Application

In this paper a comparative study of the DC DC converters is done for the standalone solar powered panel for single-phase supply. For present scenario of the electrical energy demand we require a pollution-free eco-friendly solution. Now a days Governament of India has made it compulsory that carbon footprint should be reduced at every stage while generating electricity by incorporating the photovoltaic panel. The photovoltaic panel and its accessories are required to be efficient and economical. A standalone system consists of a photovoltaic panel followed by a DC- DC converter and then a DC-AC inverter connected in series with it. This paper gives a description and comparison of various DC-DC converters such as Traditional Boost Converter (TBC), Swithced Inductor Boost Converter (SIBC) and Coupled Inductor Boost Converter (CIBC) with modeling and simulation for rated power supply along with a single-phase inverter. Though, roof top supply system has become very popular for domestic supply yet partial shading, design elements, rating of components according to the need of electric power is a big issue. Here TBC, SIBC, and CIBC are discussed mathematically and graphically then simulated in MATLAB.
