Back to Basics: Why do we need active surge suppression?

It’s well understood that unexpected electrical disturbances can cause data loss or even permanent damage to any unprotected electronic equipment in their path. Active as well as passive suppression is essential to provide comprehensive protection from all such events. This post shows why this is so, and how active suppression works to fulfil its role. Electrical events threaten electronic equipment by placing excessive electrical energy onto its input power rails in the form of a transient, a surge, or possibly both. A transient is typified as a fast-rising voltage...

Optimizing for Datacenter Power System Efficiency and Reduced Energy Costs

Optimizing for Datacenter Power System Efficiency and Reduced Energy Costs

There are no sloppy designs in datacenters. To the consumer a datacenter is just another pipe in the cloud, a conduit for their data and experiences.  However, to the industry giants wringing real dollars (in the form of demographic studies, transactional charges, and raw click-based advertising) a datacenter is the backbone of their business operations. Just like the assembly lines of Ford and the coke furnaces of Carnegie, the most efficient (least cost to operate) datacenter provides the greatest set of financial and operational benefits to their owners.

Controlled-Bus Architecture with Voltage Equalization: a System Approach to Higher Efficiency in Low Voltage DC Distribution

May 23, 2013
By

At PCIM Europe 2013, Vicor presented a paper describing how “Central Offices” for Telecommunications have been historically powered by a wide range, negative-referenced 48V distribution system. The need for simple, direct battery-power backup has been the main driver behind this choice, which is regulated by global organizations standards.
