Today improvement of existing Grid-Connected PV inverters are mainly linked to a reduction of overall Grid-connected PV system costs. The efficiency of a Grid-Connected PV inverter is above 98% and not longer the primary focus of development, though a high efficiency is a prerequisite for any kind of successful system.
In this review work, some transformer-less topologies based on half-bridge, full-bridge configuration and multilevel concept, and some soft-switching inverter topologies are remarked as desirable for grid-connected single-phase PV inverters with respect to high efficiency, low cost, and compact structure.
The inverters are categorized into four classifications: 1) the number of power processing stages in cascade; 2) the type of power decoupling between the PV module (s) and the single-phase grid; 3) whether they utilizes a transformer (either line or high frequency) or not; and 4) the type of grid-connected power stage.
In grid-connected PV system, inverter with the current control mode is extensively used because a high power factor can be obtained by a simple control circuit, and also suppression of transient current is possible when any grid disturbances occur. Table 3.
The control structures for single-phase grid-connected inverters are mostly classified into three categories: (1) control structure for single-phase inverter with DC-DC converter, (2) control structure for single-phase inverter without DC-DC converter, and (3) control structure based on Power Control Shifting Phase (PCSP).
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.
