Abstract :Abstract. In almost all solar to electrical power converter systems capacitor is placed across the solar panel. In these systems, the capacitor across the solar panel has unwanted ripple. The capacitor voltage is observed by the maximum power tracking controller and due to existence of unwanted ripple, Maximum power point tracking (MPPT) controller fall into error and MPPT will be lost. In this paper by using the power decoupled circuit in the grid connected systems, voltage ripple is eliminated and MPPT can be realized. In this paper a new inverter with high gain ratio and high efficiency base on SEPIC converter is proposed. The proposed converter maintains MPPT and improves the efficiency and voltage gain.
Keywords : Maximum Power Point Tracking, Power decoupling, SEPIC Converter, Solar panel, voltage ripple
