Central multilevel current-fed inverter with module integrated DC-DC converters for grid-connected PV plant

Abstract

This paper proposes a system of current-fed converters for the integration of a large photovoltaic (PV) plant with a utility ac grid. The system comprises a large number of PV modules with module integrated dc-dc converter. A dual inductor current-fed push-pull topology is proposed for this purpose. To meet the THD requirement along with low switching… (More)
