This, in particular, is practical for remote telecommunication applications where, through the installation of Base Stations (BSs), the development of the wireless and mobile telecommunication networks can be achieved.
In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.
The key aspects in designing an ideal power supply solution are reviewed, and these mainly include the pre-feasibility study and the thermal management of BSs, which comprise heating and cooling of the BS shelter/cabinets and BS electronic equipment and power supply components.
In the context of off-grid telecommunication applications, off-grid base stations (BSs) are commonly used due to their ability to provide radio coverage over a wide geographic area. However, in the past, the off-grid BSs usually relied on emission-intensive power supply solutions such as diesel generators.
