| Abstract: | The grid-connected photovoltaic system is a trend of photovoltaic system development. According to the character of solar array, we designed a novel grid-connected photovoltaic inverter with the function of Maximum Power Point Tracking. The inverter consists of a DC-DC converter and a DC-AC inverter and the two parts are combined by a Dclink. We adopt the Maximum Power Point Tracking and Current Tracking algorithm via a DSP controller. As a result ,the sine-wave outputes current synchronized with Grid Voltage, the efficiency and power factor of the inverter is 0.78 and 0.97 respectively. The foundational component makes up 99.6% of the output current. |
