Several power supplies for communication base stations

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. [pdf]

FAQS about Several power supplies for communication base stations

What power supply does a telecommunications system use?

For historical, practical, and technical reasons, telecom systems typically utilize a -48 V DC power supply. In the event of a grid malfunction or other emergency, telecommunications networks require dependable backup power sources. Commonly used for reserve power, lead-acid batteries can also operate at -48 V DC.

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 are the requirements of a telecom power supply?

Voltage regulation: The power supply must provide a stable and regulated output voltage per the requirements of the telecom equipment. High efficiency: Power supplies should be highly efficient to reduce power loss and energy consumption. Efficiencies of at least 90% are typical.

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.

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.

What type of power does a telecommunications network need?

In the event of a grid malfunction or other emergency, telecommunications networks require dependable backup power sources. Commonly used for reserve power, lead-acid batteries can also operate at -48 V DC. Using the same voltage for both primary and backup power makes it easier to design and maintain backup systems.
