Embodiment Construction

[0032] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0033] figure 1 is a structural diagram of a power supply according to an embodiment of the present invention, such as figure 1 As shown, the power supply includes: at least two power supply input circuits 22 for respectively receiving corresponding power supply input currents, and the at least two power supply input circuits are mutually independent; a switching circuit 24 for switching the current power supply input circuit When a fault occurs, the power supply input circuit is switched to other power supply input circuits in the at least two power supply input circuits except the current power supply input circuit. For example, the power supply is an AC-DC power supply or a DC-DC power supply. ...

Abstract

The invention discloses a power supply processing method, a power supply processing device and a power source. The method includes the following steps that: the power source receives at least two paths of power supply input current, wherein the power supply input current is independent from each other; and when a fault occurs on a power source at a power supply input circuit where the current power supply input current is located, the power supply input circuit is switched to a power supply input circuit where the other power supply input current is located, wherein the other power supply input current can be selected from all the power supply input current except the current power supply input current. With the power supply processing method, the power supply processing device and the power source of the invention adopted, the problem of power outage of a whole set when an input power supply system malfunctions in the prior art can be solved; when one path of input power supply malfunctions, the other path of input power supply can be switched in automatically; and the risk of power outage of equipment in single input power supply when the power supply system malfunctions can be avoided, and power supply cost can be decreased.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a power supply processing method and device, and a power supply. Background technique [0002] Commonly used power supplies, whether AC-DC power supply or DC-DC power supply, are mostly in the form of single output, which cannot realize redundant input. When the input power supply system fails, there is a risk of power failure of the whole machine, and the reliability is low. If two redundant Power supplies are connected in parallel to achieve input redundancy, which is costly. [0003] In the related art, when the input power supply system fails, the whole machine will be powered off, and no effective solution has been proposed. Contents of the invention [0004] The present invention provides a power supply processing method, device and a power supply to at least solve the problem in the prior art that the whole machine will be powered off when the input power supply syste...
