As global consumption of mobile network is increasing, 4G base station must be designed in a context of improvement in power efficiency. This article presents a new concept of managing the DC-to-DC converter supplying power amplifiers in base stations, targeting a factor two reduction in power consumption. This new concepts provide new specifications for base stations but also for DC-DC converter...
Despite the constant improvement in power efficiency of macro-cell base stations, the continuous capacity expansion increases considerably the global power consumption of the mobile network. This article presents a new concept of managing the DC-to-DC converter supplying power amplifiers in base stations, targeting a factor two reduction in power consumption. Details of the concept and the practical...
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...
