This paper presents a Three Port Converter with two additional Modes of operation, realized using two different sources in second port. The existing system consists of a battery, which acts as energy storage. First and third ports consist of Photovoltaic system and the Load. The Proposed System consists of Second Port with both Battery storage and wind energy system. Thus, the entire system is capable of regulating the power even at peak load demands using a bidirectional switching topology. Two extra modes of operation, namely Dual Input Single Output mode (DISO-2) and Single Input Single Output (SISO-2) are discussed in the proposed system that uses Perturb and Observe based Maximum Power Point Tracking for extracting maximum power from the Photovoltaic System. The improvements include the increase in net Efficiency of converter system with improved voltage boost ratio above six times verified using simulation results. In addition, a prototype model of the proposed system developed in the Laboratory for validation purpose.
