Global optimization of a high step-up DC-DC converter for CPV application

This paper presents the structural optimization of a DC-DC converter for concentrated photovoltaic systems. The goal is to replace cell interconnection by a high-gain boost-mirror. The aim is to improve the energy efficiency of CPV installations. After the presentation of the boost-mirror and its “adaptation” to the field of CPV, the sizing of the various components is performed (capacitors, intercellular transformer…). Then the optimization of the complete converter is presented.
