Abstract :
Offline applications with single-stage power converters (SSCs) are presented in this paper. The approach used in synthesizing the SSCs is first described, and their applications are then introduced. In addition, viable control strategies for the SSCs are addressed. The developed SSCs can fulfill multifunctions, such as input power factor correction, fast output regulation and lamp ballasting, and possess the merits of compact size, simple driver design and high reliability. Prototypes of SSCs, applied to an electronic dimming ballast and a DC regulator, are built which show high feasibility in such moderate power applications
