Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, because the switching characteristic influence of the switching transient relay and the transient change influence of the input voltage are not considered in the design of the ATS function, the voltage of the PFC circuit of the server power supply is abnormal, and the PFC control logic causes the regulation of the PFC control to increase rapidly due to the transient change of the input voltage, thereby causing the overshoot oscillation of the input current. The switch control signal output by the PFC control chip is generated according to the voltage value of the target voltage, and is different from the target voltage which is constant all the time after power supply switching and power supply access are steady in the prior art.
The embodiment of the invention discloses a dual power supply switching method of a server, which is shown in figure 1 and comprises the following steps:
s1: acquiring a power supply switching instruction, switching out a current access power supply, and accessing another power supply;
s2: updating the voltage value of the target voltage in the PFC control chip according to the principle that the voltage of the target voltage slowly rises;
s3: and outputting a switch control signal of the power supply rectifying circuit through the PFC control chip according to the current voltage value of the target voltage.
The embodiment can be applied to a power supply module of a double-input cabinet type server, a power supply module of a traditional server and other electric devices adopting a centralized power supply module of a PFC (power factor correction) control chip.
Specifically, the power switching command includes: the AC power supply is cut out and connected to the DC power supply, and the DC power supply is cut out and connected to the AC power supply. The power supply switching instruction can be sent by a user according to power supply requirements, and can also be actively generated when the power supply module detects that the original power supply is in single-circuit power failure.
Specifically, the voltage slow-rising principle may be that time or feedback voltage is used as a change basis for voltage rising, and a specific change curve may be a linear or quadratic curve, specifically, when time is used as the change basis, the voltage slow-rising principle specifically includes:
the first voltage value is used as the initial voltage of the target voltage, and the voltage value of the target voltage gradually rises along with the increase of time until the voltage value of the target voltage rises to the second voltage value.
Further, the principle of the slow voltage rise specifically includes:
the first voltage value is used as the initial voltage of the target voltage, and the voltage value of the target voltage linearly rises along with the increase of time until the voltage value of the target voltage rises to the second voltage value.
In general, the PFC control chip takes a time period as a reference unit, and further, the principle of slow voltage rise specifically includes:
and taking the first voltage value as the initial voltage of the target voltage, and increasing the voltage value of the target voltage by a preset step length in each time period along with the increase of time until the voltage value of the target voltage is increased to a second voltage value.
For example, when the cut-in power supply is a DC power supply, the initial voltage, i.e., the first voltage value, may be set to 350V, and the final voltage or the second voltage value is typically 400V. The voltage value of the target voltage can also rise in a frequency cycle of 1V, wherein the frequency cycle is the cycle of the PFC control chip outputting the switch control signal; it can be understood that although the voltage value of the target voltage rises linearly, the update frequency of the voltage value cannot be changed smoothly in real time, generally, the update frequency takes a plurality of frequency cycles as a time period, and every ten frequency cycles can be set as the update time period, that is, the preset step size of the voltage value of the target voltage rising in each time period is 10V.
Similarly, when the feedback voltage is used as a variation basis, the principle of slow voltage rise specifically includes:
and taking the first voltage value as the initial voltage of the target voltage, and increasing a preset step length for the current voltage value of the target voltage when the real-time feedback voltage of the power supply rectifying circuit reaches a voltage updating condition until the voltage value of the target voltage rises to a second voltage value.
Specifically, the voltage updating condition is a relatively stable real-time voltage environment, the power supply rectification circuit outputs the feedback voltage after being controlled by the on-off of the switch control signal, and the oscillation amplitude and the frequency of the feedback voltage reach a preset range, which means that the real-time voltage environment is relatively stable, and the next voltage updating can be performed.
It should be understood that the parameters of the first voltage value, the second voltage value, the preset step length, the time period, etc. in this embodiment can be set according to actual situations, and the numerical values are only examples.
Further, steps S2 and S3 are performed alternately, each time the voltage value is updated in the PFC control chip, the PFC control chip outputs the corresponding switch control signal until the voltage value is updated to the final voltage, that is, the second voltage value, and then the PFC control chip does not update any more, and the PFC control chip outputs the constant switch control signal corresponding to the final voltage, at this time, the entire power supply module enters the single-power-supply stable power supply state.
Referring to fig. 2, when the dual power supply of the server is switched according to the principle that the voltage slowly rises, the specific implementation includes the following steps:
s11: acquiring a power supply switching instruction, switching out a current access power supply, and accessing another power supply;
s12: taking the first voltage value as the initial voltage of the target voltage, and outputting a corresponding switch control signal of the power supply rectifying circuit through the PFC control chip;
s13: judging whether the current voltage value of the target voltage reaches a second voltage value or not; if not, the process proceeds to step S14, and if yes, the process proceeds to step S15;
s14: updating the voltage value of the target voltage in the PFC control chip according to the principle of slow voltage rise, outputting a corresponding switch control signal of the power supply rectifying circuit through the PFC control chip according to the current voltage value of the target voltage, and entering the step S13 again;
s15: and keeping the current voltage value of the target voltage as a second voltage value in the PFC control chip, and outputting a corresponding switch control signal of the power supply rectifying circuit through the PFC control chip.
The invention discloses a dual power supply switching method of a server, which comprises the following steps: acquiring a power supply switching instruction, switching out a current access power supply, and accessing another power supply; updating the voltage value of the target voltage in the PFC control chip according to the principle that the voltage of the target voltage slowly rises; and outputting a switch control signal of the power supply rectifying circuit through the PFC control chip according to the current voltage value of the target voltage. The switch control signal output by the PFC control chip is generated according to the voltage value of the target voltage, and is different from the target voltage which is constant all the time after power supply switching and power supply access are steady in the prior art.
The embodiment of the invention discloses a specific dual power supply switching method of a server, and compared with the previous embodiment, the embodiment further describes and optimizes the technical scheme. Specifically, the method comprises the following steps:
the process of obtaining a power supply switching instruction, switching out a current access power supply and accessing another power supply specifically comprises the following steps:
when a power supply switching instruction is acquired, switching a current access power supply from a direct current power supply to an alternating current power supply, and monitoring the alternating current power supply;
when the alternating current power supply meets the switching condition, cutting off the direct current power supply and connecting the direct current power supply to the alternating current power supply;
wherein the switching conditions include:
the phase of the alternating current power supply meets a switching phase interval, and/or the voltage value of the alternating current power supply meets a switching voltage interval.
It can be understood that, in order to reduce the impact of the instant when the relay is closed when the ac power supply is connected, the relay is normally closed when the phase of the ac power supply is close to 0 °, so that the switching phase interval is near 0 °, and the upper and lower limits of the interval are 0 ±, which is the angle set according to the actual situation.
Similarly, the voltage value of the ac power supply satisfies the switching voltage interval because the voltage amplitude has a corresponding phase relationship with the actual voltage value, and thus the requirement of determining the switching phase interval can be realized by determining the switching voltage interval. Further, the switching voltage interval may be set to [0V, 220V ].
It can be understood that when the switching condition is met, the alternating current power supply is switched, and the switching point is in a low-voltage position of the alternating current power supply, so that part of overcurrent impact in the circuit can be weakened.
Correspondingly, the embodiment of the present invention further discloses a dual power switching system of a server, as shown in fig. 3, including:
the switching module 1 is used for acquiring a power supply switching instruction, switching out a current access power supply and accessing another power supply;
