Abstract

To meet the requirement of the output power of grid-connected photovoltaic (PV) power generation system, the inverter should be controlled according to the output power of PV arrays. In this paper proposed method of a novel fuzzy logic control for grid connected photovolatic system. The system composed of boost converter and a single-phase full-bridge inverter connected to utility grid. The system control is based on variable universe fuzzy logic to control MOSFET switch of boost converter and single phase full-bridge inverte for grid-connected. The novel fuzzy control is analyzed in detail, which can modify universe according to the change of inputs.The simulative results show the output power of PV inverter has good quality and can provide energy with low harmonics and high power factor.
