【Abstract】 The 3 kW single-phase renewable energy grid-connected inverter based on DSP control was designed.And the key techniques of the single-phase inverter was introduced.The techniques of islanding protecting and inverter connecting with grid were discussed in detail. The system simulation and model machine test results show that the inverter can give renewable energy back to grid by high power factor.更多还原
