Abstract

The invention provides a method, a circuit and a device for controlling hot plug of a power supply, wherein the method comprises the flowing steps of: cutting off a current supply path between a power supply conversion module and a power supply bus when the power supply conversion module is contacted with the power supply bus of a work system through a connector; detecting a voltage value at the power supply conversion module side and a voltage value at the work system side; and switching on the current supply path between the power supply conversion module and the power supply bus according to the voltage value at the power supply conversion module side and the voltage value at the work system side. The method, the circuit and the device provided by the invention can effectively solve the problem of the sparking phenomenon generated at the moment of hot plug of the power supply, so that the reliability of the work system is improved.

Description

technical field [0001] The invention relates to a power supply hot swap control method, circuit and equipment, belonging to the technical field of power supply hot swap. Background technique [0002] With the development of computer and communication technology, the requirements for uninterrupted power supply of electronic systems are becoming more and more stringent. Carrying out power supply backup is a better way to solve this problem, and fast and effective power supply hot-swapping technology is the key. [0003] Power supply hot-swapping technology refers to plugging the power supply into the working system or unplugging it from the working system without affecting the operation of the working system under the working state of the power supply. The hot-swappable redundant power supply system increases the fault tolerance of the system. like figure 1 As shown, the redundancy of the power system is usually described by the method of n+x, where n represents the number ...
