Abstract: In this paper, the power quality improvement techniques with respect to various modulation algorithms for the solar Photovoltaic (PV) inverter are reviewed. In power quality, harmonics are an important concern in all the utility sectors. The factors that contribute the harmonic distortion on distribution systems include increased application of capacitors and non-linear devices. In order to improve the power quality and also to maintain stable power supply performance, an inverter topology with harmonic reduction techniques is required. The design and development of solar Photovoltaic inverter suitable for the Indian sub-continent is proposed and reviewed in terms of survey, simulation and experimental results. The proposed multi-stage inverter provides the advantage of reduced harmonic distortions and suitable for standalone and grid connected systems. The reduction of harmonics is governed by proper switching sequences required for the inverter switches. Modified multicarrier modulation techniques are developed in a single chip controller. A 3kWp solar PV plant with multistage inverter system is implemented and as per the results, the quality of power is increased and achieved the desired output voltage inspite of variations in the solar PV.
