This paper proposes a high-efficiency and high conversion gain DC-DC converter to integrate alternative energy sources into DC nanogrid. The proposed configuration takes advantage of the coupled inductor technique to attain high voltage gain and reduced switch voltage stress. The voltage stress on the switch is substantially minimized compared to the high output voltage. Therefore, a low voltage rating switch is employed to enhance conversion efficiency. Furthermore, the coupled inductor utilization eliminates the reverse recovery losses of diodes. The operation principle and steady-state analysis of the proposed converter are elaborated. A prototype is developed to substantiate the experimental performance of the proposed converter. The experimental results demonstrate coherence with the theoretical study and simulation results. The converter shows a 96.3% peak conversion efficiency.
