Adaptive Cell Converter Topology Enables Constant Efficiency in PFC Applications

Power Factor Corrected AC rectification has been addressed in a variety of ways over the past three decades; however, the wide variation of worldwide AC line has imposed significant design trade-offs. This paper explains how the Vicor PFM converter represents a breakthrough by analyzing the converter structure at three different levels of detail: in a classic bottom-up approach, three different “magnification factors” will be applied to the same structure.
