Comparative analysis of soft switching two-phase boost converter for photovoltaic system

摘要

The aim of this paper is to analyze the soft switching two phase boost converter for photovoltaic (PV) system. Nonconventional energy sources like photovoltaic interface system, the important parameters are input current and voltage ripples which affect the system performance. The advantages of two-phase boost converter include increased efficiency, reduced size and improved reliability can be used in such applications for interfacing. By adopting soft switching method, reduction in switching losses and also reduction in ripples can be achieved so that system efficiency is improved. The comparative analysis is also made among the two phase converter with different inductor coupling. The simulation study of two phase boost converter fed by PV source is carried out using MATLAB and results are presented in this paper.
