Cuk converter

The Ćuk converter is a type of electrical inverter for converting power at one DC voltage to power at a different voltage. It uses a capacitor as its main energy-storage component, unlike most other types of converter which use an inductor. It is named after Slobodan M. Ćuk of the California Institute of Technology, who first presented the design in the paper referred to below.

Pronunciation note: Ćuk is pronounced Chook, to rhyme with book.

Spelling note: it is sometimes written incorrectly as Čuk or Cúk; Ć and Č are two different letters in Serbian.
