Abstract
This work proposes a non-isolated single-switch dc-dc converter based on the integration of the classical buck and Ćuk topologies using the graft technique. The resulting converter aggregates some interesting advantages, e.g., both the input current and the current through the output stage are continuous with low ripple. A qualitative and quantitative analysis of the Ćuk-buck converter is derived, showing that the circuit is suitable for high step-down applications. Simulation results obtained with PSIM® software are presented and discussed to demonstrate the accuracy of the theoretical analysis.
