In general, on the basis of transformer, the grid-connected PV inverter topologies are categorized into two groups, i.e., those with transformer and the ones which are transformerless. Line-frequency transformers are used in the inverters for galvanic isolation of between the PV panel and the utility grid.
In the last decade, a progressive research is carried out on the development of new topologies for grid connected power converters. The reliability, power density, highest possible efficiency, and overall performance of the power converters are the areas where research is headed.
In addition, various inverter topologies i.e. power de-coupling, single stage inverter, multiple stage inverter, transformer and transformerless inverters, multilevel inverters, and soft switching inverters are investigated. It is also discussed that the DC-link capacitor of the inverter is a limiting factor.
Between the CCM and VCM mode of VSI, the CCM is preferred selection for the grid-connected PV systems. In addition, various inverter topologies i.e. power de-coupling, single stage inverter, multiple stage inverter, transformer and transformerless inverters, multilevel inverters, and soft switching inverters are investigated.
As opposed to the off-grid PV systems, the grid-connected PV does not require storage system as they operate in parallel with the electric utility grid. In addition, they supply power back to the utility grid when the generated power is greater than the load demand. Fig. 1. A typical structure of off-grid system.
In both standalone or grid-connected PV systems, power electronic based inverter is the main component that converts the DC power to AC power, delivering in this way the power to the AC loads or electrical grid.
