Transformer-less Grid Connected PV Inverter for Single Phase System

There is a strong trend in the photovoltaic inverter technology to use transformer-less topologies in order to acquire There is a strong trend in the photovoltaic inverter technology to use transformer-less topologies in order to acquire electric grid. The energy injected into the electric grid by the PV installation depends on the amount of power extracted from the PV power source and the efficient processing of this power by the DC/AC inverter. This paper extracted from the PV power source and the efficient processing of this power by the DC/AC inverter. This paper photovoltaic (PV) array voltage, but can also convert the solar dc power into high quality ac power for feeding into the grid. Simulation results confirm the performance of proposed system.
