Description

Technical Field

[0001] The present application relates to the technical field of pulse width modulation, and particularly to a method, device, and storage medium for a pulse modulation signal phase trigger for a device. Background Art

[0002] The multi-phase stable voltage power supply (VR power supply) has the advantages of reducing input current ripple, reducing output current ripple, improving transient overshoot and undershoot, and improving conversion efficiency, and is widely used in server systems to supply power to CPUs and graphics cards. For example, Figure 1 The figure shows a schematic circuit structure diagram of a three-phase regulated power supply.

[0003] The thermal design current (TDC) that one phase of the VR power supply can provide can reach 40A. As the power consumption of CPUs and graphics cards becomes higher and higher, the number of phases required for the VR power supply is also increasing. Currently, digital controllers with up to 12 phases have emerged in the industry. As the number of phases increases, the risk of overlap between the pulse width modulation drives of adjacent two phases also increases, and the probability of coupling interference between adjacent two phases also increases.

[0004] In the prior art, by taking the quotient between the maximum value of the phases of the multi-phase regulated power supply (360°) and the number of phases of the multi-phase regulated power supply, and based on the quotient between the two, the phases are triggered at equal intervals in sequence. In actual situations, adjacent phases are adjacent on the hardware board, and the pulse width modulation signals driven by them are also adjacent. This phase overlap will generate relatively large coupling interference and will greatly reduce the stability of the VR power supply.

[0005] Therefore, there is an urgent need to propose a method, device, equipment, and storage medium for a pulse modulation signal phase trigger that can adjust the trigger phase of the pulse width modulation drive signal of the multi-phase regulated power supply to reduce the coupling interference between adjacent phases and improve the stability of the multi-phase regulated power supply.

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] In the prior art pulse modulation signal phase triggering method, the pulse modulation signal is triggered according to the same phase triggering interval. The specific method is to obtain the total number of phases of the multi-phase regulated power supply, and take the quotient of the phase maximum value 360° of the multi-phase regulated power supply and the total number of phases as the phase triggering interval to trigger the phase of the pulse modulation signal. For example, as Figure 2 shown, it is the trigger phase diagram of the pulse modulation signal of the 7-phase regulated power supply based on the prior art. The coupling interference between adjacent phases is very large, and as the total number of phases of the multi-phase regulated power supply continues to increase, the coupling interference between adjacent phases will become larger and larger. To solve the above technical problems, the present application provides a pulse modulation signal phase triggering method that can adjust the trigger phase of the multi-phase regulated power supply pulse width modulation drive signal to reduce the coupling interference between adjacent phases and improve the stability of the multi-phase regulated power supply. It should be understood that in Figure 2 , the meaning of PWM is pulse width modulation, PWM1 represents pulse modulation signal 1, PWM2 represents pulse modulation signal 2, and so on. PWM7 represents pulse modulation signal 7.

[0046] The pulse modulation signal phase triggering method provided by the present application, as Figure 3 shown, provides a pulse modulation signal phase triggering method. Taking the application of this method to a 12-phase regulated power supply as an example, it includes the following steps:

[0047] Obtain the total number of phases of the polyphase regulated power supply. In this embodiment, the total number of phases of the polyphase regulated power supply is 12 phases;

[0048] Take the integer part after taking the square root of the total number of phases of the polyphase regulated power supply to obtain a first parameter, and the first parameter is 3;

[0049] Based on the first parameter and the total number of phases of the polyphase regulated power supply, group the phases of the polyphase regulated power supply according to the arrangement order of the phases to obtain the polyphase regulated power supply phase group;

[0050] According to a preset phase triggering rule, obtain the triggering phase of the pulse modulation signal within the polyphase regulated power supply phase group;

[0051] Trigger the pulse modulation signal based on the triggering phase to achieve the phase triggering of the pulse modulation signal.

[0052] In the above method for triggering the phase of the pulse modulation signal, by obtaining the total number of phases of the polyphase regulated power supply; taking the integer part after taking the square root of the total number of phases of the polyphase regulated power supply to obtain a first parameter; based on the first parameter and the total number of phases of the polyphase regulated power supply, grouping the phases of the polyphase regulated power supply according to the arrangement order of the phases to obtain the polyphase regulated power supply phase group; according to a preset phase triggering rule, obtaining the triggering phase of the pulse modulation signal within the polyphase regulated power supply phase group; triggering the pulse modulation signal based on the triggering phase to achieve the phase triggering of the pulse modulation signal. It can realize the adjustment of the triggering phase of the pulse modulation signal of the polyphase regulated power supply, not only greatly reducing the coupling interference between adjacent phases after adjustment, but also greatly improving the stability of the polyphase regulated power supply.

[0053] In one embodiment, the implementation form of the code language for taking the integer part after taking the square root of the total number of phases of the polyphase regulated power supply to obtain a first parameter is: Where m is the total number of phases of the polyphase regulated power supply, n is the first parameter, and the meaning of int() is to take the integer part.

[0054] In one embodiment, based on the first parameter and the total number of phases of the multi-phase voltage regulator, the phases of the multi-phase voltage regulator are grouped to obtain the multi-phase voltage regulator phase groups, including: based on the first parameter, obtaining the number of multi-phase voltage regulator phase groups, the number of multi-phase voltage regulator phase groups being equal to the first parameter; based on the total number of phases of the multi-phase voltage regulator and the first parameter, dividing the total number of phases of the multi-phase voltage regulator by the first parameter to obtain the maximum number of phases within the multi-phase voltage regulator phase groups; based on the multi-phase voltage regulator phase sequence and the maximum number of phases within the multi-phase voltage regulator phase groups, grouping the phases of the multi-phase voltage regulator to obtain the multi-phase voltage regulator phase groups.

[0055] Specifically, when the multi-phase voltage regulator is a 12-phase voltage regulator, the first parameter is 3. Based on the first parameter, the number of 12-phase voltage regulator phase groups is obtained as 3; based on the total number of phases of the 12-phase voltage regulator and the first parameter, dividing the total number of phases of the 12-phase voltage regulator by the first parameter to obtain the maximum number of phases within the 12-phase voltage regulator as 4; based on the 12-phase voltage regulator phase sequence and the maximum number of phases within the 12-phase voltage regulator phase groups, grouping the 12-phase voltage regulator to obtain the 12-phase voltage regulator phase groups. It should be understood that the 12-phase voltage regulator can generate pulse modulation signals 1, 2, 3... 12, where pulse modulation signal 1 corresponds to phase 1, pulse modulation signal 2 corresponds to phase 2, pulse modulation signal 3 corresponds to phase 3... pulse modulation signal 12 corresponds to phase 12.

[0056] In one embodiment, based on the phase sequence of the 12-phase regulated power supply and the maximum number of phases within the phase group of the 12-phase regulated power supply, the 12-phase regulated power supply is grouped to obtain the phase groups of the 12-phase regulated power supply, including: the number of phase groups of the 12-phase regulated power supply is 3, namely phase group 1, phase group 2, and phase group 3; the maximum number of phases within any phase group of the 12-phase regulated power supply is 4, that is, phase group 1 includes phases 1, 2, 3, and 4, phase group 2 includes phases 5, 6, 7, and 8, and phase group 3 includes phases 9, 10, 11, and 12. It should be understood that when the quotient obtained by dividing the total number of phases of the poly-phase regulated power supply by the first parameter is not an integer, the quotient is rounded up, that is, the maximum number of phases within any phase group of the poly-phase regulated power supply is obtained. For example, when the poly-phase regulated power supply is a 10-phase regulated power supply, it is calculated that the phase groups of the 10-phase regulated power supply are 3; based on the total number of phases of the 10-phase regulated power supply and the number of phase groups of the 10-phase regulated power supply, the obtained value is not an integer, then it is calculated that the maximum number of phases within any phase group of the 10-phase regulated power supply is 4, that is, the number of phases within the first two phase groups of the 10-phase regulated power supply is 4, and the number of phases within the third phase group is 2.

[0057] In one embodiment, the preset phase triggering rule includes: based on the total number of phases of the poly-phase regulated power supply being 12, obtaining the quotient of the maximum phase value of the poly-phase regulated power supply and the total number of phases of the poly-phase regulated power supply, and obtaining the actual parameter for phase triggering of the pulse modulation signal within the phase group of the poly-phase regulated power supply; based on the phase groups of the poly-phase regulated power supply, according to the preset phase triggering rule of the pulse modulation signal, obtaining the variable parameter for phase triggering of the pulse modulation signal within the phase group of the poly-phase regulated power supply; based on the product of the actual parameter and the variable parameter, obtaining the triggering phase of the pulse modulation signal within the phase group of the poly-phase regulated power supply. Among them, the maximum phase value of the poly-phase regulated power supply is 360 degrees, and it is calculated that the actual parameter for triggering the pulse modulation signal within the group is 30 degrees.

[0058] In one embodiment, the formula for obtaining the triggering phase of the pulse modulation signal within the phase group of the poly-phase regulated power supply based on the product of the actual parameter and the variable parameter is:

[0059]

[0060] Among them, m is the total number of phases of the poly-phase regulated power supply; z is the arrangement position of the phases within the phase group of the poly-phase regulated power supply, z = p - 1, p is the actual arrangement position of the phase group of the poly-phase regulated power supply; n is the first parameter; y is the arrangement position of the phase group of the poly-phase regulated power supply, y = q - 1, q is the actual arrangement position of the phases within the phase group of the poly-phase regulated power supply.

[0061] In one embodiment, the preset in-group pulse modulation signal triggering rule includes: obtaining the arrangement position of the phases within the phase group of the multi-phase regulated power supply; obtaining the arrangement position of the phase group of the multi-phase regulated power supply; obtaining the product of the arrangement position of the phases within the phase group of the multi-phase regulated power supply and the first parameter; and summing the product and the arrangement position of the phase group of the multi-phase regulated power supply to obtain the variable parameter for triggering the phase of the in-group pulse modulation signal of the multi-phase regulated power supply.

[0062] In one embodiment, the arrangement position of the phases within the phase group of the multi-phase regulated power supply is q - 1, where q is the actual arrangement position of the phases within the phase group of the multi-phase regulated power supply; the arrangement position of the phase group of the multi-phase regulated power supply is p - 1, where p is the actual arrangement position of the phase group of the multi-phase regulated power supply. Among them, the actual arrangement position of the phases within the phase group of the multi-phase regulated power supply includes: the actual arrangement sequence position of the phases within the phase group of the multi-phase regulated power supply and the actual reverse arrangement position of the phases within the phase group of the multi-phase regulated power supply; the actual arrangement position of the phase group of the multi-phase regulated power supply includes: the actual arrangement sequence position of the phase group of the multi-phase regulated power supply and the actual reverse arrangement position of the phase group of the multi-phase regulated power supply.

[0063] In one embodiment, according to the actual arrangement sequence position of the phases within the phase group of the multi-phase regulated power supply and the actual arrangement sequence position of the phase group of the multi-phase regulated power supply, the actual arrangement position of the 12-phase regulated power supply phase group where phase group 1 is located is the 1st, and the actual arrangement position of phase 1 within the 1st 12-phase regulated power supply phase group is the 1st. Then the arrangement position of phase 1 is 0, the arrangement position of the 12-phase regulated power supply phase group 1 where phase 1 is located is 0, the first parameter is 3, the product of the arrangement position of phase 1 and the first parameter is 0, and the sum of the product 0 and the arrangement position 0 of the 12-phase regulated power supply phase group is 0. Then the variable parameter for triggering phase 1 of the in-group pulse modulation signal within the multi-phase regulated power supply phase group 1 is 0. By analogy, the variable parameter of phase 2 is 3, the variable parameter of phase 5 is 1, and the variable parameter of phase 9 is 2. Based on the actual parameter and the variable parameter, taking the product of the actual parameter for triggering the phase of the in-group pulse modulation signal and the variable parameter for triggering the phase of the in-group pulse modulation signal, then the phase 1 corresponding to pulse modulation signal 1 is 0°, the phase 2 corresponding to pulse modulation signal 2 is 90°, the phase 5 corresponding to pulse modulation signal 5 is 30°, and the phase 9 corresponding to pulse modulation signal 9 is 60°. As Figure 4 shown, it is the pulse modulation signal triggering phase diagram of the 12-phase regulated power supply. Figure 4 Among them, the meaning of PWM is pulse width modulation. PWM1 represents pulse modulation signal 1, PWM2 represents pulse modulation signal 2, and so on. PWM12 represents pulse modulation signal 12.

[0064] In one embodiment, according to the actual arrangement order position of the phases within the phase group of the multiphase regulated power supply and the actual reverse arrangement position of the multiphase regulated power supply phase group, the actual arrangement position of the 12-phase regulated power supply phase group where phase group 1 is located is the 4th, and the actual arrangement position of phase 1 within the first 12-phase regulated power supply phase group is the 1st. Then the arrangement position of phase group 1 is 3, the arrangement position of the 12-phase regulated power supply phase group where phase 1 is located is 0, the first parameter is 3, the product of the arrangement position of phase 1 and the first parameter is 0, and the sum of the product 0 and the arrangement position 2 of the 12-phase regulated power supply phase group is 2. Thus, the variable parameter triggered by phase 1 of the pulse modulation signal within multiphase regulated power supply phase group 1 is 2. By analogy, the variable parameter of phase 2 is 5, the variable parameter of phase 5 is 1, and the variable parameter of phase 9 is 0. Based on the actual parameter and the variable parameter, taking the product of the actual parameter triggered by the phase of the pulse modulation signal within the group and the variable parameter triggered by the phase of the pulse modulation signal within the group, the phase corresponding to pulse modulation signal 1 is 60°, the phase corresponding to pulse modulation signal 2 is 150°, the phase corresponding to pulse modulation signal 5 is 30°, and the phase corresponding to pulse modulation signal 9 is 0°. It should be understood that in actual application scenarios, those skilled in the art can, according to the actual situation, combine the actual arrangement position of the phases within the multiphase regulated power supply phase group and the actual arrangement position of the multiphase regulated power supply phase group. For example, it can be based on the actual reverse arrangement position of the phases within the multiphase regulated power supply phase group and the actual sequential arrangement position of the multiphase regulated power supply phase group, or, based on the actual reverse arrangement position of the phases within the multiphase regulated power supply phase group and the actual reverse arrangement position of the multiphase regulated power supply phase group, or, based on the actual arrangement order position of the phases within the multiphase regulated power supply phase group and the actual reverse arrangement position of the multiphase regulated power supply phase group, or, based on the actual arrangement order position of the phases within the multiphase regulated power supply phase group and the actual sequential arrangement position of the multiphase regulated power supply phase group, and according to the preset pulse modulation signal triggering rule, obtain the variable parameter triggered by the phase of the pulse modulation signal within the multiphase regulated power supply phase group.
