Nowadays people using dc power at all places for their work convenient. So requirement of variable dc power is more. It is not easy to get high value of dc power from ac power or from low dc power. Even it is converted ac to dc that produces more losses and also need more cost for conversion. In order to avoid using of two or more number of converters for obtaining variable dc power it is enough to have this single circuit to obtain variable dc power. Zero voltage transition current fed dc to dc converter circuit is used here. To avoid the switching losses soft switching techniques are used. That improves the over all efficiency of the converter. Along with the dc –dc conversion circuit an auxiliary circuit also used for providing soft switching to the main conversion circuit.
