Assessement of Single Stage Three Phase Boost Inverter for an Islanded Microgrid

Abstract

The objective of this paper is to elucidate a single-stage resonant topology for conversion of low solar PV dc voltage to high ac voltage in an islanded microgrid. In this paper, the boost-inverter architecture that achieves both boosting and inversion functions in a single-stage with pure sinusoidal output voltage is described. The working of the proposed boost inverter is shown with one leg operation corresponding to a single phase along with the state space analysis in on and off state conditions. The central idea is to show the benefits of Boost Inverter as a reliable power modulator over the conventional conjugated usage of a boost converter and a 3 phase Voltage Source Inverter. From the simulation outcomes, the functional viability of the model is determined and evaluated.
