摘要：This paper presents the high efficiency soft-switching snubberless high step-up converter. Zero currentcommutation of current fed device is novel and makes the converter snubberless and fully soft-switched with naturalvoltage clamping. In the primary side of the circuit, zero current switching is achieved and zero voltage switching isachieved in the secondary side of the circuit. There is a single phase full bridge inverter in the secondary side of thecircuit which provides ac output voltage. In our proposed system, the supply to the load will be uninterrupted byefficiently utilizing any one of the sources like panel or battery or grid (or any two). Output voltage of the panel is fedto the converter if panel produce nominal voltage, if it fails then higher voltage magnitude from any source like batteryor grid will provide the required load voltage.
