Making Power Design Easy for the Embedded Engineer

Today many embedded systems designers are also required to develop the power chain for their system. Although embedded engineers may not have the training or experience of power system specialists, there are now a range of tools that make it easy to develop efficient, reliable and power-dense solutions for embedded applications.

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.

48 Vdc Distribution; a Safe, Practical and Efficient Solution for Equipment Racks

Vicor’s new AC Front End Module has an isolated, regulated output of 330 W at 48 Vdc. Its applications are many and varied, including powering rack-mounted equipment in telecommunications or data centres. However designers for such applications sometimes ask why the DC output has been set at 48 V rather than 12 V, or even 5 V?

First Direct 48V-to-Processor, Intel x86-compliant Solution

With increasing demands on datacenter and cloud computing infrastructure, efficient power management is a growing concern. Electricity costs can account for up to 50% of annual datacenter operating expenses. The 5% efficiency gain enabled by Vicor’s Intel compliant power solution can reduce per-processor power loss by 10W – or 30% – which can yield annual datacenter electricity savings of approximately $500,000 across 30,000 onsite processors.
