High gain DC-DC converter applied to photovoltaic system with new proposed to MPPT search

Abstract

This paper presents the development of a high gain Boost converter applied to photovoltaic (PV) system. This converter raises its input voltage and injects its output current at a constant 311 Vdc bus, using the maximum power point tracking (MPPT). The new proposal seeks the MPPT is to connect each module a converter for a high gain greater accuracy in finding the point of maximum power. The converter will work with input voltage of 17.4 Vdc, output voltage of 311 Vdc and power of 100 W.
