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...

Keeping in view the falling tariff in Solar PV, there has been talk of having competitive bidding in wind power also, however it would be a challenge to opt for competitive bidding in case of wind as the wind power is very site specific – even in locations which are high wind zone as compared to solar which is more widespread phenomenon...
