Ćuk converter

The Ćuk converter (Serbo-Croatian: [tɕûːk], English: /ˈtʃuːk/) is a type of buck-boost converter with low ripple current. A Ćuk converter can be seen as a combination of boost converter and buck converter, having one switching device and a mutual capacitor, to couple the energy.

Similar to the buck-boost converter with inverting topology, the output voltage of non-isolated Ćuk converter is typically inverted, with lower or higher values with respect to the input voltage. While DC-to-DC converters usually use the inductor as a main energy-storage component, the Ćuk converter instead uses the capacitor as the main energy-storage component. It is named after Slobodan Ćuk of the California Institute of Technology, who first presented the design.
