COMPARISON OF SINGLE BOOST CONVERTER AND HIGH STEP-UP CONVERTER FOR DISTRIBUTED GENERATION PHOTOVOLTAIC-INVERTER SYSTEM

Abstract

This paper deals with comparison of single boost converter and step-up DC-DC converters for PV module application. There is a growth in the area of PV generation connected to the grid. This paper proposes a high step-up DC-DC boost converter to boost the output voltage of PV cell. The output of high step up converter is converted into AC using a single phase inverter .A filter is introduced in the output to reduce the harmonics. High step up DC-DC converter for distributed generation employing photovoltaic inverter is modeled and simulated using Matlab/Simulink. The results of single boost converter system are compared with the results of high step up DC-DC converter system.
