In this paper, a single-phase grid-connected inverter applying a boost coupled inductor is proposed for photovoltaic (PV) generation system and PV grid connected systems to enhance integration of a Single phase inverter with Photovoltaic panel to form independent embedded photovoltaic modules. DC 20V to 40V is boosted up to DC 400V, successfully inverted to AC 220V.This will efficiently convert solar energy into electrical energy to comply with the requirements of the local load, or connect the converted electrical energy into the grid. Simulations were conducted using PSIM software to testify the effectiveness of the proposed scheme. Also the experiment on boost circuit was conducted to testify the boosting ability of the coupled inductor.
