Abstract : A modified single-inductor boost converter (MSLBC) can contribute a ultrahigh voltage boosting capability without using any transformer or coupled inductor. This converter topology is highly suitable for applications where better performances, including improved voltage gain, efficiency, power density, and reliability are needed. The major contributions of the MSLBC are ultrahigh voltage boosting capability without using transformer or coupled-inductor, single-inductor structure to realize continuous input current, simple topological structure, lower voltage stress of switches and intrinsic small duty cycle to enhance the system efficiency. Results are obtained by simulating the converter using MATLAB/SIMULINK R2020b.The simulation results shows that the converter has high voltage gain and achieves a peak efficiency of 81%T˙ he converter is controlled using TMS320F28335 microcontroller. The experimental results obtained from converter prototype confirm the theoretical considerations and the simulation results. The results shows that the modified single inductor boost converter can be used for wide conversion range applications with high voltage gain and low ripple content.

Keywords : Boost Converter, Transformer less, High Gain, Efficiency, Single Inductor.
