Abstract

The invention discloses a multi-power supply control system comprising n power supplies, n loads which are correspondingly connected with the n power supplies, and n multi-power supplies control devices; each multi-power supply control device is correspondingly connected between each power supply and the primary load thereof; each multi-power supply control device comprises at least one second branch which is connected with other secondary loads; when the power supplies in the system work normally, each power supply supplies power to the corresponding primary load through a first branch; and when the system has any fault power supply, the primary load which is correspondingly connected with the fault power supply supplies power to the primary load corresponding to the fault power supply through the fault-free power supply which is connected with the second branch. The invention uses a simple hardware circuit, and solves the problem that when a plurality of power supplies supply power to a plurality of loads, some power supply fails to work suddenly and all the loads are powered off because other power supplies are overloaded instantaneously.

Description

technical field [0001] The invention relates to the field of multi-power supply technology, in particular to a multi-power supply control device and a system thereof. Background technique [0002] At present, in today's large-scale switching equipment, especially in the field of data centers, most of them adopt modular design. Users can configure different module boards according to different application requirements, and in order to ensure the maximum power supply efficiency of equipment, for this The power supply system of modular data center equipment also adopts the mode of multi-power supply, so that users can choose different quantities and types of power supplies for system power supply according to the number of different modules and cards currently configured. In this way, the power supply efficiency of the power supply equipment is improved, and the equipment cost is saved. However, the power consumption of the data center is also very large. Usually, the number o...
