Do telecommunication towers contain Base Transceiver Stations (BTS)?

Abstract: Telecommunication towers for cell phone services contain Base Transceiver Stations (BTS). As the BTS systems require an uninterrupted supply of power, owing to their operational criticality, the demand for alternate power sources has increased in regions with unreliable and intermittent utility power.

What is a 3G base station converter?

In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.

What is a preferred power supply architecture for DSL applications?

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.

Why should a telecom network be prepared for a power outage?

It is also possible to shut down certain equipment during times of lower site trafic to simply save on energy consumption. Preparing your network for power outages caused by weather and natural disasters with advanced technology will increase the resilience, reliability, and eficiency of your telecom sites.

What types of power systems are used in communications infrastructure equipment?

Communications infrastructure equipment employs a variety of power system components. Power factor corrected (PFC) AC/DC power supplies with load sharing and redundancy (N+1) at the front-end feed dense, high efficiency DC/DC modules and point-of-load converters on the back-end.

What is a multi-output power supply design?

Multiple output designs may also employ a complex regulation scheme which senses multiple outputs to control the feedback loop. Voice-over-Internet-Protocol (VoIP), Digital Subscriber Line (DSL), and Third-generation (3G) base stations all necessitate varying degrees of complexity in power supply design.
