Abstract
This article presents a new problematic in DC-to-DC converter realized for 4G macro cell base station with efficiency improvement concepts. These concepts from EARTH project target a factor two reduction in 4G base station power consumption. The concepts are presented and detailed. DC-to-DC converter specifications needed are discussed. A practical implementation of a 500 kHz and zero to 112W buck converter is presented. The prototype achieves 94% power efficiency and a good stability over the complete power range.
