【Abstract】 Solar energy utilization is a tendency, because it has no environmental pollution.The paper illustrates the method of photovoltaic grid-connected inverter with MPPT based on grid-connected current and the characteristic of solar array.The authors have established a control model adopting the feed forward of grid voltage and current tracking technology. The sine grid-connected current and unity power factor are achived.更多还原
