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.
PV inverters may be classified assingle-stage or two-stage. The typical PV converter is based on a two-stage converter [ 1 - 7 ]. Two-stage configuration is mainly used because of its advantages of easy control since maximum power point tracking (MMPT) control and current injection control are decoupled at different stages.
The two stage operation has proved to have better and higher efficiency. From the simulation results it can be easily concluded that two stages grid connected PV inverter has better and stable response as compared to the single stage grid connected PV inverter.
Two-stage configuration is mainly used because of its advantages of easy control since maximum power point tracking (MMPT) control and current injection control are decoupled at different stages. In addition, this gives the freedom to push the switching frequency of the DC–DC converter to an order higher than the inverter (the second stage) one.
Numerous inverter circuits and control schemes can be used for PV power conditioning system. For residential PV power generation systems, single-phase utility interactive inverters are of particular interest –. ].
Single stage grid connected PV system In single stage operation the photovoltaic array is directly connected with the utility power network through PV inverter as shown in Fig. 1. In this case the maximum power point tracking and delivery of real power to the grid is achieved by the inverter stage itself.
