Ericsson’s digital power module wins awards from Electronic Products China

Ericsson has won the Best Application award and Best Non-Isolated Digital Power Module categories in the Top 10 Power Product Awards run by the media outlet Electronics Products China. The prizes were awarded to Ericsson’s BMR461, the company’s advanced digital POL point-of-load (POL) regulator that features Dynamic Loop Compensation (DLC) based on ‘state-space’ or ‘model-predictive’ control, guaranteeing stability and achieving the optimum dynamic performance without requiring any external components.

Electronics Products China, which celebrates the very best of innovation in power electronics, has run its prestigious awards event for several years. In 2014, the judging panel included a professor from the Nanjing University of Aeronautics and Astronautics alongside a senior engineer from China Power Supply Society with a close affiliation to Shanghai Association for Science and Technology.

"The successfully launched BMR461 came to fruition as a result of close cooperation between Ericsson R&D and product development teams based in Sweden and China," commented Patrick Le Fèvre, Marketing and Communication Director, Ericsson Power Modules. "We have won several awards within the Chinese electronics industry in just a couple of years, which demonstrates the highly efficient and innovative products being developed by Ericsson."

The Dynamic Loop Compensation circuitry built into the BMR461 negates the requirement for external components such as RC networks to adjust control loop compensation parameters. As some board designs employ 30 or more 12A POL regulators, the BMR461 significantly simplifies the design and maintenance process for power designers. Additionally, the BMR461 represents significant savings both in terms of cost and time while also improving reliability.
