In this paper, a soft-switched non-isolated high voltage gain interleaved bidirectional dc-dc converter with low voltage stress on switches for battery storage systems is presented. In hybrid energy storage systems, there should be a conversion unit with a wide conversion ratio to be the interface circuit in these systems. Unlike the conventional interleaved converters, the proposed converter is able to provide the same conversion ratio for the whole range of duty cycles. The theoretical analysis of the proposed converter is reconfirmed through the experimental results. In the final version of the study, the experimental results for 1MHz will also be presented.
