This paper presents modern single switch dc to dc converter modelling and control of a grid connected renewable energy. The system consists of a Photo voltaic cells, a SEPIC DC-DC converter used for Maximum Power Point Tracking (MPPT), a three-phase grid converter. A nonlinear control performance of a three-phase inverter is proposed to recompense unstable load currents. It permits whole control of DC bus voltage, while calculating power flow from the PV cells to the system and guarantying objective sinusoidal grid currents at unity Power factor under varying solar irradiation. Moreover, a sliding mode control system for a SEPIC DC-DC converter is used to extract the MPPT. The proposed control techniques have exposed good performance. The system is validated using the "Power system Block set" simulator under different values of the solar irradiation.
