Abstract: According to one aspect of the present disclosure, a single-stage converter includes a rectifying circuit and a buck-boost circuit. The buck-boost circuit includes an inductor with a center tap configured to supply an output of the buck-boost circuit to the rectifying circuit. The buck-boost circuit also includes first and second interleaved arms arranged in parallel with a voltage input of the single-stage converter. The first and second interleaved arms are each coupled to the inductor and include a plurality of switches operable to control the output of the buck-boost circuit.
