Five Minutes With… Martin Hägerdal, Ericsson

Power is something that end users can never get enough of. However, those same users are demanding smaller and lighter systems, meaning that smaller power systems are needed. This is a dilemma that Ericsson Power Modules must wrestle with on a daily basis. In my discussion with Martin Hägerdal, President of Ericsson Power Modules, which is an independent company within the Ericsson Group, we talked about how efficiency need to continue its rise, and where digital power can have a significant play here. Finally, we discussed whether it’s ever possible to attain 100% efficiency.
