This paper makes an attempt to develop grid connected solar photovoltaic array power conversion using sine wave inverter. The proposed system makes use of single stage power conversion with maximum power point tracking and sine wave inverter (SWI) as interfacing unit into the grid. Here perturb & observe method of maximum power point algorithm is used to regulate the DC link voltage of the SWI and to synchronize the grid utility voltage with the current for attaining near unity power factor operation under varying environmental conditions. The simulation results presented in this paper verifies the operation of proposed SWI topology such that the AC output is free from the higher order harmonics and grid voltage and current are in phase.
