Performance Analysis for Single-Stage Buck-Boost Inverter

Abstract

In this paper a three-phase single stage buck-boost inverter is presented. The proposed inverter consists of a DC-AC inverter that merges DC-DC converter for boosting the input voltage and DC-AC inverter for interfacing the DC input and AC grid. The proposed paper based on the three-phase full bridge inverter, where only one inductor and switch have been added to step up the input voltage. The proposed inverter is featured by some advantages such as a reduction in the number of semiconductor power switches, and control implementation simplicity. The operation of the inverter is studied and analyzed in this paper. The three-phase inverter is simulated using MATLAB software package-tool to verify the performance of the topology.
