Abstract—In many industrial applications, it is required to convert a fixed-voltage dc source into a variable –voltage dc source. DC-DC converters can convert DC voltage from one level to another level without using the AC transformer. This paper describes a new strategy for converting the DC voltage to step-up and step-down efficiently and effectively. It can be accomplished using Buck, Boost, Buck Boost and Ćuk converter. Amongst which Buck converter can only step down the DC voltage and Boost converter can only step up the DC voltage. But the Buck Boost and Ćuk converter can step up or step down the voltage. For ripple in the output current and requirement of filter, Buck Boost converter has been intentionally avoided. Also, experience shows that Buck Boost is an unreliable converter which may malfunction at any time during operation. And hence, Ćuk converter is chosen for the conversion of the DC voltage. Though the Ćuk converter has an inverted output but with suitable connection and also a converter with zero ripples, it can be used successfully.
