THREE PHASE GRID-CONNECTED PHOTOVOLTAIC UNIVERSAL BRIDGE INVERTER APPLYING A BOOST CONVERTER

In this paper, a three phase grid connected universal bridge inverter using a boost converter is suggested for photovoltaic (PV) systems and grid connected systems to improve performance of three phase inverter connected to the grid. The PV grid system has a disadvantage that the output voltage of PV array is low and we need to boost then in order to efficiently convert them into alternating voltage. The boost inductor boosts the output of the PV array to a suitable level so that inverter could convert it into alternating form. The DC/AC inverter is most important part of the PV systems
