Abstract
The invention discloses a novel three-phase photovoltaic grid-connected inverter system, wherein the system can be combined to grid after outputting the direct current to different photovoltaic arrays to independently boost; the system has good compatibility to the accessed photovoltaic array; the system boosts the corresponding photovoltaic array respectively through the BOOST circuit and tracks and controls the maximum power point of the BOOST circuit through a controller, so that the tracking range of the maximum power point is enlarged, and the direct current side voltage and the inverter conversion efficiency are improved; the system can be combined and connected with different photovoltaic arrays to achieve combination to the grid through single inverter, so the novel three-phase photovoltaic grid-connected inverter system saves cost and improves the voltage of the grid-connected side, and meanwhile, meets different photovoltaic array combination ways and different environmental requirements and improves the light energy utilization rate and the system generating efficiency.
