The buck–boost converter is a type of DC-to-DC converter (also knownas achopper) that has an outputvoltagemagnitude that is either greater than or less than the input voltage magnitude. It is used to “step up” theDC voltage, similar to atransformerfor AC circuits. It is equivalent to...
A new DC–DC buck–boost converter with a wide conversion ratio is presented in this paper. The proposed buck–boost converter consists of a combination of modified boost converter and ZETA converter, which has the advantages of both converters such as continuous input/output current and positive...
