Abstract
In this study, a quadratic boost converter has been proposed. The topology of the proposed converter is based on Cuk and conventional boost converter. The low number of components besides the high voltage ratio, is one of the proposed converter advantages. Moreover, the continuous input current, makes it possible to employ the proposed converter for renewable applications. Furthermore, the high value of the voltage ratio with the low value of the duty cycle an achieved purpose in this paper. The introduced converter has been designed for the continuous current mode. The operating modes, operational relations, stress parameters of semiconductors, practical voltage ratio, mathematical relations of efficiency, comparison with another step-up typologies and small-signal analysis were done for the proposed converter. Matlab software was used for dynamic studies of the proposed converter. In the end, simulation and experimental results were provided and compared with each other. The simulation results were made up by PLECS as a simulation engine.
