Description
Technical field
The present invention relates to server power supply technique field, a kind of method reducing server system power input surge voltage is specifically provided.
Background technology
Along with the fast development of internet industry in recent years, the demand of industry to server is increasing.Meanwhile, to the system performance of server, have higher requirement in the aspects such as system stability.With regard to the part of power supply, this just requires the voltage stabilization of system, particularly input voltage, can not occur excessive surge voltage, otherwise easily generation is smashed subelement or caused the abnormal behaviours such as system exception shutdown, very large to the harm of server.
Due to capacitive reactance and the induction reactance of Circuits System; when the unlatching of circuit or shutoff or electrical source exchange; inevitably produce surge voltage; it is a lot of that this so-called surge voltage can exceed normal voltage; exceed more than 50% of normal voltage even sometimes; this just increases the risk of the abnormal behaviours such as the breakdown or triggering system overvoltage protection of a lot of components and parts, and to system stability, such risk requires that more and more higher server system has very large harm.
Summary of the invention
Technical assignment of the present invention is for above-mentioned Problems existing, provides a kind of method simple, easy to operate, and effectively can protect the method for the reduction server system power input surge voltage of server system stability.
For achieving the above object, the invention provides following technical scheme:
Reduce a method for server system power input surge voltage, a capacitance resistance buffer circuit (RCsnubber) is set at power input and reduces system surge voltage, strengthen the voltage stability of system power supply input end.Described capacitance resistance buffer circuit (RCsnubber), can consume circuit surge voltage of producing in start electrification or other electrical source exchange processes, and the rising of the input voltage making system stationary linear more, increases the stability of system with this.
As preferably, described capacitance resistance buffer circuit (RCsnubber) can consume the energy exceeding server normal working voltage part.
As preferably, the capacitance of described electric capacity is chosen as 2 times of the parasitic capacitance in loop, and resistance is chosen as L/C(wherein: L is the parasitic inductance value in loop, and C is the parasitic capacitance in loop).Because the capacitive reactance of different system and induction reactance are different, therefore, need to select the capacitance of different electric capacity C and the resistance of resistance R according to different systems, and select the power consumption specification of resistance by calculating the power consumption that resistance consumes.
As preferably, the power consumption of described resistance consumption be C*V*V*F(wherein C be the parasitism in loop, V is system input voltage, and F is system concussion frequency).
The present invention has following outstanding beneficial effect: capacitance resistance buffer circuit (RCsnubber) can consume the energy exceeding server normal working voltage part; even if when the unlatching of circuit or shutoff or electrical source exchange; also surge voltage can not be produced; it is not breakdown that this just protects a lot of components and parts; can not the risk of the abnormal behaviour such as triggering system overvoltage protection, stability when farthest protection server system is in normal work and in the unlatching of circuit or shutoff or electrical source exchange.
Embodiment
Be described in further detail below in conjunction with the method for embodiment to reduction server system power input surge voltage of the present invention.
