ABSTRACT
this paper presents a review of the state-of-the-art developement of small-power grid-connected inverter topologies for practical implementation.Unique requeriments for small distributed power generation system include low cost,high efficiency and tolerance for an extremely wide range of input voltage variations.Selection guide lines are give based on applications requirements and cost consideration.Special attentions are focused on the analysis of switch utilization factor in comparing competitive inverter topologies
