This paper summarized the behavior of the inverter as we know the Photovoltaic (PV) has several advantages such as less harmless to the environment. Furthermore, grid-connected PV energy generation represents a renewable energy growing alternative that is becoming more competitive due to the new favorable governmental laws and policies as recently introduced. In this regard, PV systems that supply power directly to the grid are becoming more popular because of the cost reduction due to the lack of a battery subsystem. The main components of a grid-connected PV (GPV) system include a series-parallel connection arrangement of the available PV panels and a power conditioning system in charge to extract and properly transfer the maximum available power present at the PV generator to the grid. A GPV system based on a single central inverter is one of the most prevailing configurations since, under uniform irradiance conditions of the PV panels; it represents a good trade-off between the extracted energy and the design complexity of the power inverter. In this configuration all of the available PV panels are connected to a single power stage. One of the most typical central inverter power converter topology is the single-phase single-stage full-bridge inverter...........................
