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.
