Building a Better –48 VDC Power Supply for 5G
In this article, we present a stackable and interleaving multiphase high voltage inverting buck-boost controller that will resolve all the requirements/challenges
For 5G, infrastructure OEMs are considering combining the radio, power amplifier and associated signal processing circuits with the passive antenna array in active antenna units (AAU). While AAUs improve performance and simplify installation, they also require the power supply to share a heatsink with the power amplifier for cooling.
With the increase of power density and voltage drops on the power transmission line in macro base, it is recommended to use HVDC system for the 5G network. Requirements to ICT equipment Power Supply Unit (PSU) and supporting facilities. -42V. It means that if the voltage drop is more than 6V, the ICT equipment will be protected.
The Sectional area of the 4G power supply cable is calculated by 6mm2 The Sectional area of the 5G power supply cable is calculated by 16mm2. installed a DC/DC converter to increase the system 57V or 60V.
The radius of coverage area of 5G high-frequency base stations will be less than one-tenth of that of 4G base stations, and the coverage area of 5G high-frequency base stations will be less than one percent of that of 4G base stations. The deployment of macro base stations is difficult and the site resources are not easy to obtain.
According to the principle of mobile communication, the transmission distance and frequency of the signal are inversely proportional when the power ratio of receiving and transmitting is constant. The frequencies of 4G base stations are generally from 2.3GHz to 2.6GHz, and the frequencies of 5G high-frequency base stations are above 28GHz.
Therefore, in 5G networks, high-frequency resources will no longer use macro base stations, micro-cells become the mainstream, and the small base stations will be used as the basic unit for ultra-intensive networking, that is, small base stations dense deployment.
