Abstract:

This paper focuses on advancement and development of power converter technology in PV systems generally used in grid connected residential setup. Grid-connected PV systems play a key role in power systems, which are connected by power electronics converters. The conventional inverters with transformers connected in PV grid-tied generation system are now being replaced by transformerless inverter. Thus this paper gives an overview on inverter technologies available for connecting solar photovoltaic (PV) modules to a single-phase utility grid. Various transformerless inverter topologies are presented, compared, against demands, lifetime and operations. Finally, a topology is picked out and suggested to be most suitable for single PV module used in residential application.
