چکیده :

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 beside 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 is an achieved purpose in this paper. The introduced converter has been designed for the continuous current mode (CCM). The operating modes, operational relations, stress parameters of semiconductors, practical voltage ratio and comparison with other step-up typologies have been done for the proposed converter. Matlab software has been used for dynamic studies of the proposed converter. In the end, simulation and experimental results have been provided and compared with each other. The simulation results have been made up by PLECS as a simulation engine.
