Performance Analysis of a Multi-Source, Single-Output, Buck-Boost DC-AC Converter Feeding Active Power to a 3-Phase Distribution Grid

Abstract

No doubt that, power electronics plays an important role in the modern industry and power system networks.This paper presents the performance analysis of a multi-source, single-output, buck-boost dc-ac convertersuitable for use in different applications such as feeding ac loads from photovoltaic systems. In this paper,the performance of the proposed converter is studied, through power simulation program (PSIM), underdifferent modes of operation during feeding active power to a distribution network. The most importantfeatures of the proposed converter are the possibility to control voltage, frequency, voltage and frequencytogether, and the low value of the total harmonic distortion (THD) in the voltage and current waveforms.
