Grid Integrated Micro Inverter for PV Module with Anti -Islanding and MPPT Schemes

Abstract: From the economic perspective, densely populated areas can generate great amounts of electric power by installing PV panels on its rooftops and it can be fed in to the grid. In this paper describes a grid tied micro inverter for photovoltaic applications. The system consists of a Cuk converter connected with a full-bridge current source inverter. The connection of micro inverter systems to the grid can raise several challenges, as the islanding detection and extracting maximum available power from PV module. In this sense, if the system is unable to detect the islanding situation, it may cause power quality degradation, electrical safety threats to maintenance crews, and damage to the devices that connected at the same power grid .In order to maximize the power extraction from the photovoltaic module it is mandatory, to make use of a MPPT algorithm
