Abstract
This paper presents a system for maximum power point tracking (MPPT) and maintains an output voltage supply by a photovoltaic solar panel (PV). Two-stage of converters SEPIC are connected in series. The P&O MPPT algorithm is applied in the first stage to obtain the maximum power of PV, independently of irradiance and temperature that depend on environmental conditions. The passivity based-control regulate the output voltage in the second stage. This study aims to operate the PV at maximum power point (MPP) in variable environmental conditions to increase efficiency and provide appropriate current and voltage to load applied. The controller is designed using the mathematical average model of the SEPIC converter. Later, the whole system is simulated in the PSIM software simulator circuit; the results obtained confirm the proposed system's effectiveness.
