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.
A simple new chemical method for repairing and recycling notoriously difficult carbon fiber composites has been developed by the Fraunhofer Institute for Applied Polymer Research. An entire component can be completely recycled, including reclaiming its expensive carbon fibers for reuse.
In today’s connected world we are seeing the beginning of connected homes, smart grids, self-driving automobiles, drones, and many other amazing devices. Out of all the soon-to-be connected devices, which device poses the greatest dangerous to its users and society?
