Isolated AC-DC Converter with PFC

Unlike low frequency ac-dc front ends usinga PFC boost stage and a dc-dc down converter, Vicor Corp.'s PFM VIBRICK module provides isolation, voltage transformation and PFC regulationin a single stage using advanced, high-frequency soft switching technology. Itsthin profile liberates system architects from dimensional constraints of bulky powersupplies. Its small size, coupled with secondary-side energy storage at 48V,allows greater flexibility and creativity to design slim products withcompetitive advantages. Its modular, scalable power component functionalitysupports efficient, cost-effective power systems with 'N+1' redundancy.

This initial PFM module complements an array of VI BRICKand V.I Chip converter building blocks that Vicor Corp. says provides unparalleled density, efficiency and connectivity fromthe wall plug to the point of load.
