Özet

The Ćuk converter is a DC-DCconverter which is essentially a cascade connection of the conventional boost converter and the buck converter having a capacitor to couple the energy .Its advantages mainly include the use of fewer number of switches, smooth input as well as output current and magnetic component integrability, etc.. Input current and output current have small ripple. However, requirement of capacitor C1 with large ripple current capability is disadvantages. The high ripple has a negative effect on the Ćuk converter, such as overheating,noisy operation and break down. In this study, the current and voltage ripple of Ćuk converter were found with the help of the Matlab/Simulink program. Ćuk converter contains two inductor and two capacitor. Hence it is fourthorder DC-DC converter. It provides output voltage both higher as well as lower than the input voltage. Ćuk converters are used frequently in communication systems and renewable energy sources.
