Unlike low frequency ac-dc front ends using
a PFC boost stage and a dc-dc down converter, Vicor Corp.'sPFM VI
BRICK module provides isolation, voltage transformation and PFC regulation
in a single stage using advanced, high-frequency soft switching technology. Its
thin profile liberates system architects from dimensional constraints of bulky power
supplies. Its small size, coupled with secondary-side energy storage at 48V,
allows greater flexibility and creativity to design slim products with
competitive advantages. Its modular, scalable power component functionality
supports efficient, cost-effective power systems with 'N+1' redundancy.
This initial PFM module complements an array of VI BRICK
and V.I Chip converter building blocks that Vicor Corp. says provides unparalleled density, efficiency and connectivity from
the wall plug to the point of load.
