A communication equipment power supply system and its control method

Abstract

The invention discloses a communication equipment power supply system, which includes an electromechanical management module, a power supply plane and at least 2N switching power supply modules, and an input voltage type detection unit in the switching power supply module is used to detect the voltage type connected to the switching power supply module, The monitoring communication unit is used to detect the physical slot information of the switching power supply module in the power supply plane, and report the input voltage type, physical slot information and operation status information of the switching power supply module to the electromechanical management module; the electromechanical management module It is used to determine the load distribution plan of each switching power supply module, and issue an output voltage adjustment command to the corresponding switching power supply module according to the load distribution plan; the switching power supply module changes the duty cycle of the drive power conversion circuit according to the output voltage adjustment command received, thereby Adjust the size of the DC output voltage. The power supply system of the invention has flexible power supply and high power supply efficiency. The invention also provides a control method for the power supply system of the communication equipment.

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...
