Abstract: The transformer-less single-switch dualinductor boost converter configuration can realize high voltage gain with low voltage and current stresses; therefore, it is suitable for high gain applications. It has low voltage stress on components compared to other typical transformer-less single-switch high voltage gain converters like switched inductor boost converter, quadratic boost converter and quasi-Z-source boost converter. Moreover, the current stress of the front-end diode and the rear- end inductor is also relatively low. Therefore, the conversion efficiency is enhanced while keeping the cost low. The operation principles and steadystate characteristics analysis of the con- verter is discussed in detail. Results are obtained by simulating the converter in MATLAB/SIMULINK R2021b. The simulation results shows that the converter has high voltage gain and achieves a peak efficiency of 89%. The converter is controlled using TMS320F28335 microcontroller. The experimental results obtained from a 6W converter prototype confirm the theoretical considerations and the simulation results.
