With drastically increasing demands for cloud computing and big data processing, the electric energy consumption of data centers in the U.S. is expected to reach 73 billion kWh by 2020 [1], which will account for approximately 10% of the U.S total electric energy consumption. A large portion of this consumption is caused by losses from inefficient power delivery architectures that require a lot of attention for improvements [2], [3].

48V-to-1V Conversion – the Rebirth of Direct-to-Chip Power

48V-to-1V Conversion – the Rebirth of Direct-to-Chip Power

During last week’s PCIM Europe event in Nuremberg, Germany, direct 48V-to-1V power conversion architectures were a significant topic, mostly outside of the exhibit floor. Vicor was quietly showing its latest generation of 48V direct-to-chip power components. Ericsson Power Modules and Efficient Power Conversion were holding invitation-only meetings where future designs of 48V direct to load power conversion architectures were the focus of the discussions. By the end of 2017, several vendors are expected to be offering dc-dc converters delivering 48V-to-1V direct conversion.
