Abstract
This paper presents a study related to a recently proposed quadratic boost converter topology: the so-called Low Energy Storage Quadratic Boost (LES-QB) converter. Unlike traditional quadratic boost converters, the LES-QB converter achieves high voltage gain with reduced energy storage in its passive components, enabling more compact designs. Recently, an improved operation was proposed based on the optimized selection of capacitors. This work focuses on the implementation and validation of the optimized design. The converter was built and tested, and its operation was compared against that of a non-optimized configuration. The results demonstrate that the correct selection of capacitors leads to a reduced switching ripple without increasing the size of the converter. Experimental results are provided.
