Power supply system of communication equipment and control method thereof

Abstract

The invention discloses a power supply system of communication equipment. The system comprises an electromechanical management module, a power supply plane and at least 2N switching power supply modules, wherein an input voltage type detection unit in each switching power supply module is used for detecting the type of a voltage accessed to the switching power supply module, detecting the physicalslot position information of the switching power supply module in a power supply plane, and reporting the type of the input voltage, the physical slot position information and the operation state information of the switching power supply module to the electromechanical management module; the electromechanical management module is used for determining a load distribution plan of each switching power supply module and issuing an output voltage regulation command to the corresponding switching power supply module according to the load distribution plan; and each switching power supply module changes the duty ratio of the driving power conversion circuit according to the received output voltage adjustment command so as to adjust the magnitude of the DC output voltage. The power supply systemis flexible in power supply and high in power supply efficiency. The invention further provides a control method of the communication equipment power supply system.

Description

technical field [0001] The invention belongs to the technical field of power supply for communication equipment, and more specifically relates to a power supply system for communication equipment and a control method thereof. Background technique [0002] Usually, in order to ensure the reliability of the communication equipment power supply system, in addition to the N (N ≥ 1) main switching power supply modules for normal power supply in the actual application of communication equipment, the same number of N (N ≥ 1) standby switching power supply modules will also be introduced. Switching power supply module, 2N switching power supply modules are introduced into the communication equipment and the number of power supply terminals to be provided in the computer room is also 2N. The communication equipment uses N or 2N partition planes to supply power to all the machine disks in the communication equipment. [0003] The communication equipment adopts N+N redundant backup mod...
