Ericsson's 3E design kit enables easier exploration of digital power architectures

3E Gold Edition software simplifies monitoring and configuration of digitally-controlled dc-dc converters

3E platform can optimize operating efficiency in real-time to conserve energy and minimize operating costs
Enhanced performance, Energy management, and End-user value are the key design objectives of Ericsson’s 3E range of digitally-controlled dc-dc converters. A second generation of the design kit, with extended features, now simplifies their implementation within PMBus systems.

The 3E Gold Edition design kit hardware comprises two boards that accommodate one or two intermediate-bus converters and up to six point-of-load regulators. Sample devices include the BMR453 and BMR454 intermediate-bus converters together with examples of the BMR462, BMR463, and BMR464 point-of-load regulators. The boards can operate independently or be plugged together to form a representative PMBus-controlled power system. The design kit includes a USB-to-PMBus adapter that provides a seamless interface between the 3E GUI Gold Edition software running on a Windows PC and the target 3E family dc-dc converters. The 3E GUI Gold Edition software package together with an extensive library of technical papers and supporting information that accompanies the hardware elements can be download from Ericsson Power Modules website.

"The 3E Gold Edition software makes it easier than ever for users to precisely configure each converter in a system and monitor its performance, which in turn encourages users to explore and develop methods such as dynamic bus-voltage control that can optimize system-level power consumption to accommodate the wide load variations that today’s network infrastructures present" said Patrick Le Fèvre, marketing director at Ericsson Power Modules.
