30 years of technology innovation in saving energy at the board level. Ericsson first to introduce digital power management and control in board-mounted power solutions. Trends include move from analog to digitally controlled converters and growing use of dynamic energy management to deliver significant power savings.

This month Ericsson commemorates thirty years of being at the forefront of developing DC/DC power technology: from the development of its first on-board DC/DC modules to the FRIDA II platform based BMR456 and BMR 457 Advanced Bus Converters that are ideal for implementing the Dynamic Bus Voltage technology in advanced power systems architectures. It was in late April 1983 that Ericsson launched the world's first high-frequency switching DC/DC power modules, called the PKA family.

"Ericsson has played a substantial role in a DC/DC power market that has seen considerable innovation over the past thirty years," said Patrick Le Fèvre, Marketing and Communication Director, Ericsson Power Modules. "The company has consistently delivered leading-edge products including high-efficiency and digitally controlled advanced bus converters and point-of-load regulators to help its customers in data-coms and other industries to make significant energy savings."

Many award-winning introductions from Ericsson have followed the launch of the PKA family, including: the PKC series in 1987; the PKF MacroDens family in the 1990s; the PKM-C series in 2003; the first fully digitally controlled and programmable family of advanced bus converters, the BMR453 series in 2008; and the BMR456 and BMR457 advanced bus converters in 2012, offering advanced board-power-consumption monitoring and control technologies to enable significant energy savings.
