The proliferating frequency bands and modulation schemes of modern cellular networks make it increasingly important that base-station power amplifiers offer the right combination of output power, efficiency and multi-band support – at both peak and average power levels. PAs are the main energy consumers in modern base stations.
In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.
The imperative here is to operate base stations that can flexibly adjust to traffic demand. Certainly, the transition to and deployment of 5G communications has an inherent requirement for adoption of smart power management in the underlying hardware.
A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
These tools simplify the task of selecting the right power management solutions for these devices and, thereby, provide an optimal power solution for 5G base stations components.
