Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. 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 arbitrarily with each other.

[0025] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0026] After the design of the existing solution is completed, due to the large amount of capacitance at the load end, the current passing through the power device at the beginning of power-on is relatively large, which may mistakenly trigger the power pro...

Abstract

The invention discloses a hot plugging device and a hot plugging realization method. It involves electronic circuit technology, and solves the problem that it cannot be powered on normally when the load changes. The device includes: a power device, the device also includes an adjustable protection circuit connected to the power device, the adjustable protection circuit turns on or off the power device by outputting a control pulse; the adjustable protection circuit includes a controller , further comprising a gate resistor and / or a gate capacitor, and the current protection point of the power device is set by adjusting the value of the gate resistor and / or gate capacitor. The technical scheme provided by the invention is suitable for server power-on control, and realizes hot swapping of flexible configuration.

Description

technical field [0001] The invention relates to electronic circuit technology, in particular to a hot plugging device and a method for realizing hot plugging. Background technique [0002] In the server field, for easy installation and maintenance, hot-swappable applications appear on many products. Hot swap is a form that can support server nodes to perform hot maintenance operations without affecting the work of other nodes. It can effectively protect the power supply components on the node when plugging and unplugging the node with power, and ensure that the node is not damaged. [0003] In the hot-swap design, the protection point is designed through parameter setting, so that the controller turns off the power device before the power device withstands the energy that can cause damage, thereby protecting the device on the node. [0004] However, in some cases, the set current protection point may be low, and when the load is capacitive, it may lead to failure to power ...
