A photovoltaic AC fusion converter

The aim of this paper is to describe the conception of a newly developed simple power converter which fuses the photovoltaic power and the AC power of the distribution network. The design consideration, a detailed circuit and the characteristics of the fusion mode of this power converter are discussed. The results of a preliminary field test are reported to facilitate the understanding of the fusion mode. The use of this power converter is a cost-effective alternative technology that promotes energy conservation.
