Analysis and Design of a Multi-Port DC-DC Converter for Interfacing PV Systems

A high-frequency multi-port (HFMP) direct current (DC) to DC converter is presented. The proposed HFMP utilized interface a photovoltaic (PV) system. presented compact and can perform maximum power point tracking. It consists of transformer with many identical input windings one output winding. Each winding connected PV module through an H-bridge inverter, the tracked using perturb observe (P&O) technique. bus rectifier. detailed analysis operation DC-DC are Extensive numerical simulations conducted, system computer aided design (PSCAD)/electromagnetic transients including (EMTDC) software, evaluate dynamic behavior interfacing scheme. In addition, experimental setup built verify performance converter.
