FAQS 4
What is a two-stage grid-connected inverter for photovoltaic (PV) systems?
In this study, a two-stage grid-connected inverter is proposed for photovoltaic (PV) systems. The proposed system consist of a single-ended primary-inductor converter (SEPIC) converter which tracks the maximum power point of the PV system and a three-phase voltage source inverter (VSI) with LCL filter to export the PV supplied energy to the grid.
How does a grid connected dual-stage inverter work?
In the proposed grid-connected dual-stage inverter, the direct axis current, Id, is observed, which serves for the inverter stage to set Vdc. These actions define the DC-DC converter’s input characteristic behavior, which determines the PV array operation point . When Id is maximized, the PV array operates on MPOP.
