RECTIFIER CIRCUIT MANAGEMENT SYSTEM, SUCH AS FOR USE IN CELL SITE POWER SYSTEMS

摘要

Systems, apparatus, methods, and manufactures for conserving power in a communications system such as a communications service cell site or cell site. The methods include adjusting the RF coverage of the cell site antenna, selective control of the RF output transmit power, selective control of the communications bit rate, transfer of communications to other cell sites, adjustment of indicators such that mobile devices transfer communications to other cell sites, and reallocation of logical slots between radios in the cell site. In some examples, the cell site employs a power controller. The power controller may utilize a switching circuit to produce two different voltages from a single battery string during a commercial power failure with improved conversion efficiencies. In another example, a power controller may manage multiple rectifiers so that the rectifiers operate more efficiently, such as with approximately equal runtime and with regular testing.

主权项

1. A non-transitory computer-readable medium carrying instructions that, when performed by a processor, perform a method for conserving power in a wireless communications system, the method comprising:
detecting a reduced availability of a power source for the wireless communications system,
wherein the wireless communication system forms part of a wireless telecommunications network; monitoring current drawn by the wireless communications system,
wherein the wireless communications system has at least one online rectifier,
wherein the at least one online rectifier rectifies an input source and provides an output voltage and current to the wireless communications system,wherein the wireless communications system has at least one offline rectifier,
wherein the at least one offline rectifier does not rectify an input source and does not provide an output voltage and current to the wireless communications system; selecting, in accordance with a rotation policy or when detecting a reduced availability of the power source, at least one rectifier to bring online or at least one rectifier to take offline; and switching, in accordance with the rotation policy, at least one rectifier online or offline.
