Ericsson unveils new power modules to reduce power consumption


By GreenTech Lead Team: Leading telecom equipment vendor Ericsson has unveiled FRIDA II platform, the
latest digital-power Advanced Bus Converter platform, designed for use in
telecom and datacom applications.

The new FRIDA II platform reduces energy consumption and
decreases the requirement for hard cooling – the new platform will also bring
higher reliability, lower CO2 emissions and lower Total Cost Of Ownership
(TCO2).

Ericsson introduced the
digitally controlled DC/DC Advanced Bus Converters in 2008. “Now, in this major
step forward in the company’s continuous quest to deliver energy-optimized
solutions, the FRIDA II platform will further enable its customers to reduce
their energy consumption and carbon footprint,” said Patrick Le Fèvre,
marketing and communication director of Ericsson Power Modules

The highly advanced power controller, in conjunction with
control algorithms, reduces the number of components used in the FRIDA II
platform by approximately 10 percent. This contributes to a reduction in cost
and a further increase in reliability. The platform’s integrated transformer
and feedback components designed to meet 2250 VDC isolation requirements for
applications requiring this high level.

Built around the capabilities of the 32-bit ARM7TDMI-S
microprocessor core, the FRIDA II platform integrates brand new hardware and
firmware that has been optimized to guarantee the highest efficiency at any
point of operation. The platform offers a tightly regulated output voltage
across the entire operational range – from 36V to 75V – together with an
unprecedented output response to input disturbances such as line transients.

FRIDA II  also addresses the challenges faced by DC/DC
board-mounted power supplies in telecom and datacom applications, such as in
Advanced Telecommunications Computing Architecture (ATCA or AdvancedTCA) or
remote telecom equipment that is connected to an unstable power grid.

Ericsson’s proprietary dead-time control algorithm has also been
augmented with additional functionalities to reduce switching power losses and
ease component stress during switching, Integrated transformer layout and the
use of leading-edge power transistor technologies enables the FRIDA II platform
to deliver the high level of performance required in Information and
Communication Technology (ICT) applications.

The first product based on the FRIDA II platform will be a
quarter-brick advanced bus converter, called the BMR456, which will deliver an
output power of 400W and above; followed by a new eighth-brick format device,
the BMR457, which will deliver an output power of 250W and above.

Recently, KPN International’s subsidiaries E-Plus Group and KPN
Group selected Ericsson
to upgrade their mobile backhaul in Germany and Belgium,
respectively, over the next three years.
