A DC to DC converter with a high voltage gain is necessary to enhance the power output of fuel cell and solar panel installations. This paper discusses a novel, non-isolated, high-gain, and highly efficient active switched inductor impedance source-based DC-to-DC converter. The suggested converter exhibits a high voltage gain at a low duty ratio. All three switches in the converter operate at the same switching frequency and duty ratio, making the control scheme remarkably simple. A comprehensive analysis of the converter’s continuous conduction mode steady state is provided. To validate the functionality of the recommended converter, simulations are conducted using MATLAB. The simulations are performed with an input voltage, V in , of 10V, a switching frequency, f s , of 100kHz, and a fixed duty ratio, δ, of 0.4. The simulation outputs are presented to demonstrate the performance characteristics of the proposed converter. With an input voltage of 10V, the output voltage is measured at 120V, resulting in a calculated gain of 12 for the proposed converter.
