| Abstract: | In this paper,the system of two-stage grid-connected photovoltaic was introduced,then its topological structure was analyzed.In the boost circuit may achieves the maximum power point tracking using the fuzzy control,and the inverter circuit can achieves the grid-connected control with the classic double-loop control.The simulation system model has been constructed by using MatlabR2010,and the simulation result shows that the frequency and phase of the inverter output current are the same with those of the grid voltage,and the maximum power point has been tracked effectively. |
