A Single-Switch High-Gain Cascaded Boost–SEPIC Converter Using Small Wind Turbine for Renewable Energy Applications

This paper deals with a power electronics topology that combines the features of both a boost converter and a SEPIC in a cascaded configuration using small wind turbines, to efficiently convert the variable and often low-voltage output of the turbine’s generator into a stable and usable form for charging batteries or feeding power to the grid. Its purpose is to efficiently convert the variable and often low-voltage electrical output generated by the small wind turbine into a stable and usable form of electrical energy. A specialized power electronics converter is needed as an interface for conditioning the generated power from the renewable energy source. The output power from a wind turbine is collected via a cascaded converter. The experimental data from the suggested system’s implementation in the smart energy laboratory demonstrate a sizable improvement over the current converter.
