Performance of a Single Switch Non-Isolated DC/DC Converter with Coupled-Inductor for Renewable Energy Applications

This study focuses on the analysis and simulation of a high-gain non-isolated converter with a coupled inductor. The proposed structure has significant advantages; one of the features of this converter is its high gain rate at low-duty cycles. The number of semiconductor components in this converter has been minimized, which in turn reduces design complexities. Additionally, the low voltage stress on the power switch, the common ground capability, and the low ripple in the input current are also among the strengths of this converter. These features contribute to increased efficiency and performance of the converter, thereby improving its overall operation. To validate the accuracy of the mathematical analysis conducted, simulation results in the PSCAD/EMTDC software have also been presented.
