Recent Advances on Grid-Connected PV Inverters
The last decade has seen marked prog- ress in the research and development of new power converter topologies for PV applications. The main research ef- forts have concentrated on the highest possible efficiency, power density, and reliability of the converter to further increase the overall performance of the PV installation. In the majority of cases, the newly emerged topologies are the full-power converters in which the whole amount of the PV panel (or PV string) power has to be processed.
