Description

technical field

[0001] The invention relates to the technical field of communication, in particular to a MicroTCA power supply system and a transmission method for managing power supply. Background technique

[0002] Micro Telecommunication Computing Architecture (Micro Telecommunication Computing Architecture, MicroTCA) uses standard Advanced Mezzanine Card (AMC) modules to build a small-capacity and low-cost modular communication platform, which is mainly used in small telecommunications in the central office (Central Office) equipment or enterprise-class communications equipment.

[0003] MicroTCA system structure such as figure 1 As shown, the system includes: a power module (Power Module, PM), a MicroTCA management switching module (MicroTCA Carrier Hub, MCH), AMC and a fan module (Cooling Unit, CU).

[0004] refer to figure 2 , the MicroTCA power supply system adopts a star architecture, and the power module PM mainly includes a power conversion module, an enhanced...
