Abstract
Presented is a single-stage power converter topology allowing for power factor correction during operation. The topology utilizes an integration of Ćuk converter and single-ended primary inductance converter (SEPIC) topologies to provide AC-to-AC, AC-to-DC, DC-to-AC, and AC/DC-to-AC operation. Shared use of the Ćuk converter's output inductor by the SEPIC-type circuit elements provides continuous output current, typically unknown to a SEPIC converter. Application of the single-stage power converter topologies may be had in a line conditioner circuit, a battery charger circuit, and as an uninterruptible power supply (UPS).
