Generally, renewable energy sources (RESs) such as solar and wind energy systems have variable output due to their dependence on the weather condition. Hence, numerous converter structures with variable voltage gain have been introduced, which can be used to regulate the output voltage of RESs. Providing a high dynamic voltage gain with even a small input voltage was realized by developing conventional DC-DC converters, such as Zeta, Sepic, and Cuk Converters. But these conventional converters cannot provide high voltage gains with non-extreme duty cycles. In this paper, it is aimed to design a new single-switch DC-DC power converter without employing a large number of components. This topology provides higher dynamic voltage gain with a lower duty cycle, continuous input current, and lower voltage stress on the components. The performance of the converter is proved by comparison and simulation results obtained in MATLAB/Simulink environment.
