| Abstract: | The solar energy was applied widely in recent years,as a kind of renewable energy. Photovoltaic （PV） grid technology became the key and core of the most efficiency ways of using solar energy. A current control technology with a fixed switching frequency which could track the power was put forward,through analyzing the traditional PV grid inverter control strategy. The results of the sumulation showed that the network voltage and gridconnected current were basically synchronic. And the power factor of grid system was 1 approxomatively,which met design requirement. |
