This study proposes a new high step-up DC-DC converter based on a novel super-lift structure and coupled inductor. The energy stored in the leakage inductance of the coupled inductor is recovered to the converter output, which leads to a snubber-less operation and consequently a fewer-component, lower-cost and more-efficient converter. This feature also reduces voltage stress and the current peak of the active switch without using a snubber circuit. Analysis of continuous current mode of the proposed converter considering the leakage inductance has been demonstrated. Moreover, a comparison between several converters has been done for further information about similar research works. Experimental results such as voltage and current waveforms and efficiency curve have been presented to show the practical characteristics of the proposed converter.
