In this paper presents, design and implementation of CUK converter. The CUK converter topology has often been modified for more functions or better performances. As for performances, the research on the CUK converters is concentrated on lowering switching or conduction loss, reducing component sizes, improving system efficiency, mitigating voltage or current stress, speeding up transient responses, etc. The operation of CUK converter is quite different from operation of PWM converters. The principle motivation behind the development of the CUK converter has been their ability to provide unity power factor at constant duty cycle and reduced switching losses. It has many advantages like easy implementation of the transformer isolation, protection against high inrush current, low current ripple and also less Electromagnetic Interference (EMI). The controller effectiveness is validated by simulating the CUK converter in simpower systems toolbox of MATLAB/SIMULINK.
