Abstract :
In this paper a high power factor pre-regulator with high efficiency is presented. In the proposed scheme one converter is used, but it does not process all the power delivered to the load. The power is processed less than once, resulting in an efficient converter. The proposed pre-regulator can be used with a traditional regulator or a regulator with improved efficiency, resulting that the power is processed one and half times or less than once respectively. Analysis, simulation and experimental results of the converter are presented.
