This paper proposes an interleaved buck-boost converter with fewer switches. A single buck converter is followed by n parallel interleaved boost converters in the proposed converter. Aside from the reduced switch count, the proposed converter has the following benefits: soft start-up and shutdown capabilities. Furthermore, the buck stage protects power electronic devices and isolates the supply during load failure or overload. Furthermore, with the same switching scheme, the proposed converter can function as an interleaved boost converter for high voltage gain requirements. Furthermore, it provides quick dynamic performance with a smooth transition from buck to boost mode. This paper investigates the proposed three-phase interleaved buck-boost converter's eight operating zones for non-overlapping gate signal operation.
