Conventionally, grid connected photovoltaic energy conversion systems are composed of a DC-DC converter and an inverter. The DC-DC converter is controlled to track the maximum power point of the photovoltaic array and the inverter is controlled to produce current in such a way that the system current has low Total Harmonic Distortion (THD) and it is in phase with the utility voltage. The efficiency of the conventional system is low because the DC-DC converter and the inverter are connected in series. The purpose of this article is to design a photovoltaic generation system for connection in a three-phase system using only a DC/AC inverter...

This article discusses the power quality issues and how is the unwanted component (called harmonic) introduced. Consequence of harmonics according to their sequence will be different and most precarious also. Moreover, different strategies according to different cases are discussed. We have discussed four different cases. Whereever necessary, the mathematical analysis is shown with output waveform to prove the arguments...
