Abstract

A novel, single-phase soft-switched boost ac-dc rectifier that operates with power factor correction (PFC) is proposed in this paper. The rectifier is a modified boost voltage doubler converter that is well suited for low line input applications and operates with half the switch voltage stresses than those found in a standard boost converter. Soft-switching in the converter is achieved using a zero-current switching (ZCS), quasi-resonant technique. In the paper, the converter and its modes of operation are discussed, its method of control is explained, and its feasibility is demonstrated with experimental results obtained from a prototype.
