Ericsson Outlines Power Technologies To Save Energy In Datacenters

Oct 25, 2012– Stockholm, Sweden  (Techreleased) –A long-term pioneer in delivering leading-edge digital power solutions to reduce board power consumption, Ericsson has laid out its vision to system architects developing equipment for computing-intensive environments such as datacenters. The increasing demand for more Internet services and cloud computing is driving both the expansion and building of new datacenters around the world. A key challenge for operators is the minimization of energy expenditure at the board level. Ericsson believes that a significant aid to this process is the use of advanced Dynamic Bus Voltage architectures. This vision was presented by Ericsson at last month’s Electronics Goes Green (EGG) congress in Berlin.

Today, the standard power architecture increasingly being used is the Intermediate Bus Architecture (IBA), which uses intermediate bus converters (IBCs) to convert a traditional 48 VDC distribution-level power line used in telecoms to typically a static 12 VDC. This first ‘down-conversion’ 12V level feeds a number of DC/DC point-of-load (POL) regulators, which supply the final load voltages at a chip’s logic supply levels of 3V or below. The choice of 12 VDC has been made to ensure a high enough voltage to deliver all the power required by the board, or load, in times of high data traffic. However, this approach becomes highly inefficient when the traffic demand is low.

“Dynamic Bus Voltage is a technology that makes possible to reduce board power consumption from anywhere between 3 and 10 percent, depending on the board application,” said Patrick Le Fèvre, Marketing and Communication Director, Ericsson Power Modules. “The potential for energy saving is a very substantial one, especially when taking into account the fact that 1W saved at the board level can result in a 3W saving at the power grid level.”

Ericsson 3E* BMR456-DBV and BMR457-DBV Advanced Bus Converters offer unprecedented performance and flexibility to system architects developing equipment for information and communication technologies (ICT) requiring smart and efficient board power solutions.

In June 2008, through close cooperation with board and systems designers, Ericsson was the first company to release a 21st century 3E power architecture composed of PMBus-compliant ABCs and POL converters that can be fully integrated into the rest of the digital chain of processors and associated components.

* Enhanced Performance, Energy Management, and End-user Value are the key benefits delivered by Ericsson’s range of 3E digitally controlled DC/DC converters.
