The conventional power conditioning units require a DC-DC converter to deliver the required power to the dc load. This paper presents a CUK converter topology that provides DC-DC conversion along with voltage buck and boosts depending upon the Duty cycle. When the output voltage required more than the output voltage of single level at that time multilevel CUK converter can be used. In a Multi-level CUK converter topology requires less power conversion stages and reduces the size of power conditioning units and components. In this paper, the design stages of components of the Single level and Multi-Level CUK converter is presented and hardware is implemented and results are obtained for different duty cycle.
