Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
It should be understood that in the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" for describing an association relationship of associated objects, indicating that there may be three relationships, e.g., "a and/or B" may indicate: only A, only B and both A and B are present, wherein A and B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of single item(s) or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", wherein a, b, c may be single or plural.
In a large system such as a server, a power supply is an extremely important part. If the power supply is short-circuited, accidentally powered off and the like, the system cannot work normally. In order to ensure the reliability of the power supply, redundant multiphase power supplies are often used for the power supply of important electronic systems. When one power phase of the multi-phase power supply has a fault, the fault power supply can be closed, and other power supplies work cooperatively to supply power to the system. In practice, there is also a requirement for the number of failed power supplies that the multiphase power supply can accept. For example, the M +1 redundant multi-phase power supply can ensure that the power supply equipment can still normally supply power when 1 power supply phase fails, and the M +2 redundant power supply can ensure that the power supply equipment can still normally supply power when 2 power supply phases fail.
Referring to fig. 1, a specific structure of a conventional multiphase power supply is illustrated by way of example.
The power phase controller is connected to a plurality of protection controllers, and each protection controller is connected to a corresponding power phase. The power phase controller sends PWM control signals to each power phase through the protection controller, controls the cooperative work of each power phase, and achieves multi-phase redundant power supply of the power receiving equipment. In the example shown in fig. 1, power supplies 1, 2 and 3 constitute power output 1, and power supplies 4 and 5 constitute power output 2. When a certain protection controller detects that the corresponding power phase fails, the fault information is sent to the power phase controller, the fault phase is removed, and the other power phases belonging to the same power output work cooperatively to complete power supply. For example, for power output 1, initially the power phase controller controls power sources 1, 2 and 3 to work cooperatively to generate power signals for power supply. When power phase 2 fails, the protection controller corresponding to power phase 2 detects the failure, which removes power phase 2 and sends the failure information to the power phase controller. The power phase controller controls the power sources 1 and 3 to work cooperatively to generate power information.
It can be seen that in the prior art, with the determination of the hardware circuit, each power output is determined by which phases, and therefore, there is no room for adjustment. For example, referring to fig. 1, after the hardware circuit is formed, the power output 1 can only be a three-phase power supply consisting of power supplies 1, 2 and 3 when there is no fault. The power output 2 can only be a two-phase power supply consisting of power phases 4 and 5. If the design requirement is changed, only the hardware circuit of the power supply device can be changed. And because different products have different requirements on the phase number, the redundancy mode and the like of the power supply, after the design of the power supply module of one product is finished, the power supply module is difficult to directly transplant to another product. Briefly, the prior art design solutions lack flexibility and versatility.
Therefore, according to the power supply equipment and the control method and device thereof provided by the embodiment of the application, one switch is added between every two adjacent power supply phases, and the setting of the output phase number and the redundancy mode of the power supply equipment is realized by controlling the switch states of all the switches, so that the application flexibility and the universality of the power supply equipment are improved. It should be noted that the adjacent phases refer to adjacent corresponding numbers on the power phase controller or adjacent in a link relationship.
Based on the above-mentioned ideas, in order to make the above-mentioned objects, features and advantages of the present application more comprehensible, specific embodiments of the present application are described in detail below with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 2, the diagram is a schematic structural diagram of a power supply device according to an embodiment of the present application.
The power supply device provided by the embodiment of the application comprises: the main control module 210, the power phase control module 220, the N power phase output modules 230 and the N-1 switch modules 240; n is an integer greater than 2;
a first end of the main control module 210 is connected to a first end of the power supply control module 220, each second end of the power supply control module 220 is connected to a first end of each power supply phase output module 230, and an output end of each power supply phase output module 230 is used for connecting to a powered device (not shown in the figure); a switch module 240 is connected between the output ends of two adjacent power supply output modules 230; each second end of the main control module 210 is connected to the control end of each switch module 240;
it can be understood that fig. 3 illustrates a power supply device provided in an embodiment of the present application by taking N-3 as an example, and the structure of the power supply device is similar to this when N is another value. In the embodiment of the present application, adjacent phases refer to adjacent corresponding numbers on the power phase controller or adjacent connection relationships.
In the embodiment of the application, the number of the power outputs of the power supply equipment and the number of the phases of each power output can be set by changing the switching state of each switching module, so that the flexibility and the universality of the power supply equipment are realized. As an example, the switch module 240 may be implemented by any one or more switching devices, and is not limited herein. In practical applications, the powered device may be connected to the output terminals of one or more power source output modules 230 of the power source device according to actual power supply conditions, which are not listed here.
The main control module 210 is configured to control the on-off state of each switch module 240 according to the output setting information of the power supply; and also for sending output setting information to power phase control module 220;
the power supply control module 220 is configured to receive the output setting information, and send a power supply driving signal to the corresponding power supply phase output module 230 according to the output setting information;
the power phase output module 230 is configured to, when receiving the power driving signal, output a corresponding power signal to the connected powered device according to the power driving signal.
In the embodiment of the present application, the output setting information of the power supplies specifically refers to the setting of the number of power outputs of the power supply device and the number of power phases corresponding to each power output, for example, the output setting information may specifically be two power outputs, where power output 1 includes 3 power supplies, and power output 2 includes 2 power supplies (i.e., the example shown in fig. 1). The main control module 210 controls the on-off state of the switch module 240 connected between the output ends of the two adjacent power output modules 230 according to the output setting information, and can set the output number of the power supply devices and the phase number of each power output, thereby realizing the flexibility and universality of the application of the power supply devices.
In a specific example, assuming that N is 5 and the power supply device has a structure as shown in fig. 3, the main control module 210 may control the switch module 1, the switch module 2, and the switch module 4 to be turned on and the switch module 3 to be turned off according to the output setting information, and output a three-phase power output (e.g., 2+1 redundant power) and a two-phase power output (e.g., 1+1 redundant power); the main control module 210 can also control the switching tubes 1, 2, 3, and 4 to be turned on according to the output setting information, and output a five-phase power supply (e.g., a 3+2 redundant power supply), and so on.
In this embodiment, the main control module 210 further sends the output setting information to the power phase control module 220, so that the power phase control module 220 outputs the power driving signal to the corresponding power phase output module 230, and controls the power phase output module 230 to output the corresponding power signal to the connected powered device to supply power to the connected powered device. As an example, the power driving signal may be a PWM signal, which is determined according to an actual control manner of the power phase output module 230. The power phase output module 230 may be any power phase output module, and the principle thereof is the prior art in the field and is not described again.
Continuing with the example shown in fig. 3, when the main control module 210 controls the switch module 1, the switch module 2, and the switch module 4 to be turned on and controls the switch module 3 to be turned off according to the output setting information, the power phase control module 220 sends a power driving signal to each power phase output module 230 according to the output setting information, and the power phase output modules 1-3 cooperatively work to output a three-phase power and the power phase output modules 4 and 5 cooperatively work to output a two-phase power.
In some possible implementation manners of the embodiment of the present application, the power phase control module 220 is further configured to detect a working state of each power phase output module 230, and when it is detected that any one or more power phase output modules 230 are faulty, close the faulty power phase output module 230, control the remaining power phase output modules 230 redundant to the faulty power phase output module 230 to continue to supply power to the powered device, and send corresponding fault information to the main control module 210.
Continuing with the example shown in fig. 3, when the main control module 210 controls the switch module 1, the switch module 2, and the switch module 4 to be turned on according to the output setting information, and controls the switch module 3 to be turned off, if the power supply control module 220 detects that the power supply output module 1 is faulty, and it is the power supply output modules 2 and 3 that are redundant with the power supply output module 1, the power supply output module 1 is turned off, the output power drive signal is adjusted to control the power supply output module 2 and the power supply output module 3 to work cooperatively to continue to supply power to the power receiving device, and fault information of the fault of the power supply output module 1 is sent to the main control module 210.
It should be noted that, in practical applications, since the powered device has a certain requirement (i.e., a redundant power supply condition) for the redundancy of the power supply, when the power supply device does not satisfy the requirement, normal power supply to the powered device cannot be achieved. For example, when outputting a three-phase power, the powered device requires at least two power phase output modules to operate normally (i.e. 2+1 redundant power), and at most one failed power phase output module exists, and if 2 or 3 failed power phase output modules exist, the powered device cannot be powered.
Therefore, in some possible implementation manners of the embodiment of the present application, in order to ensure normal power supply of the power supply device, the main control module 210 is further configured to receive the fault information, determine the power phase output module 230 without fault in the power supply device according to the fault information, and determine whether the power phase output module 230 without fault in the power supply device satisfies the redundant power supply condition. The main control module 210 is further configured to, when the fault-free power phase output module 230 does not satisfy the redundant power supply condition, update the output setting information according to the fault-free power phase output module 230 and the redundant power supply condition, control the on-off state of each switch module 240 according to the updated output setting information, and send the updated output setting information to the power supply control module 220.
In this embodiment, when the power phase output module 230 without a fault in the power equipment meets the redundant power supply condition, the output setting information may be updated to control the switch pile of the switch module 240 to adjust the output mode of the power equipment, so as to ensure normal power supply for the powered equipment.
Continuing with the example shown in fig. 3, when the main control module 210 controls the switch module 1, the switch module 2, and the switch module 4 to be turned on according to the output setting information, and controls the switch module 3 to be turned off, if the power output modules 1 and 2 fail, the redundant power supply condition of the 2+1 redundant power supply is not satisfied, the main control module 210 may control the switch modules 1 to 3 to be turned on and the switch module 4 to be turned off, the power output modules 3 and 4 are used to output the two-phase power supply with the minimum requirement for the powered device, and the power output module 5 is used to output the one-phase power supply with the minimum requirement for another powered device.
It can be understood that the power phase control module 220 may output corresponding power driving signals to each power phase output module 230 according to the updated output setting information, so that the power phase output module continues to output power signals meeting the power supply requirement of the powered device.
Referring to fig. 4, the figure is a schematic structural diagram of another power supply device provided in the embodiment of the present application. This figure provides a more specific power supply apparatus than that of figure 3.
In this embodiment, the main control module may specifically include: a main controller 211 and a switch controller 212;
a main controller 211 for transmitting output setting information to the power phase control module 220 and the switch controller 212;
and a switch controller 212 for receiving the output setting information and controlling a switching state of each switch module 240 according to the output setting information.
In the embodiment of the present application, the switch controller 212 may be implemented by a Complex Programmable Logic Device (CPLD). The main controller 211 communicates with the power phase controller 220 and the switch controller 212 using an Inter-Integrated circuit interconnect bus (I2C).
Of course, in practical applications, the main controller 211 and the switch controller 212 may be integrated in the same device, and are not limited herein.
In some possible implementation manners in this embodiment of the application, with continued reference to fig. 4, the power supply control module may specifically include: a power phase controller 221 and N protection controllers 222; the protection controllers 222 correspond to the power phase output modules 230 one to one;
a power phase controller 221, configured to receive the output setting information and send a power control signal to the corresponding protection controller 222 according to the output setting information;
the protection controller 222 is configured to send a power driving signal to the corresponding power phase output module 230 according to the power control signal when receiving the power control signal.
It is understood that the protection controller 222 may include a driving circuit (e.g., a MOS driving circuit) corresponding to the power source output module 230.
In one possible design, the protection controller 222 is further configured to detect an operating state of the corresponding power phase output module 230, close the corresponding power phase output module 230 when the corresponding power phase output module 230 fails, and send a corresponding failure notification to the power phase controller 221;
the power phase controller 221, further configured to send a power control signal to the target protection controller when receiving the fault notification, and send fault information to the main control module 210; the target protection controller is a protection controller corresponding to the remaining power phase output modules redundant to the failed power phase output module.
Continuing with the example shown in fig. 3, when the main control module 210 controls the switch module 1, the switch module 2, and the switch module 4 to be turned on according to the output setting information and controls the switch module 3 to be turned off, if the protection controller 222 corresponding to the power phase output module 1 detects that the power phase output module 1 has a fault, the protection controller 222 corresponding to the power phase output module 1 turns off the power phase output module 1, and sends a fault notification of the power phase output module 1 having the fault to the power phase controller 221. Redundant with the power phase output module 1 are power phase output modules 2 and 3 (i.e., target power output modules), and the power phase controller 221 adjusts the output power driving signal to control the power phase output module 2 and the power phase output module 3 to work cooperatively to continue supplying power to the powered device, and sends fault information of the fault of the power phase output module 1 to the main control module 210.
In this embodiment, in a plurality of power phase output modules included in the power supply apparatus, output ends of adjacent power phase output modules are connected through a switch module, a switching state of each switch module is controlled by using the main control module according to output setting information of a power phase, so as to change a multiphase power supply mode of the power supply apparatus, and the output setting information is sent to the power phase control module by using the main control module, so that the power phase control module controls the corresponding power phase output module to output a corresponding power signal to a connected power receiving apparatus according to the output setting information. The power supply equipment provided by the embodiment of the application realizes the adjustment of the phase number and the redundancy mode of the output power supply of the power supply equipment through the control of the switch module connected between the output ends of the power supply phase output modules, can adapt to the power supply requirements of different equipment, and improves the flexibility and the universality of the application of the power supply equipment.
Based on the power supply device provided by the above embodiment, an embodiment of the present application further provides a power supply device control method applied to any one of the power supply devices provided by the above embodiment.
Referring to fig. 5, the figure is a schematic flowchart of a power supply device control method according to an embodiment of the present application.
The power supply device control method provided by the embodiment of the application comprises the following steps:
s501: the main control module controls the on-off state of each switch module according to the output information of the power supply.
S502: the main control module sends output setting information to the power supply control module.
In the embodiment of the present application, the output setting information of the power supplies specifically refers to the setting of the number of power outputs of the power supply device and the number of power phases corresponding to each power output, for example, the output setting information may specifically be two power outputs, where power output 1 includes 3 power supplies, and power output 2 includes 2 power supplies (i.e., the example shown in fig. 1). The main control module controls the on-off state of the switch module connected between the output ends of the two adjacent power supply output modules according to the output setting information, the output quantity of the power supply equipment and the phase number of each power supply output can be set, and the flexibility and the universality of the application of the power supply equipment are realized.
In this embodiment, the main control module further sends the output setting information to the power phase control module, so that the power phase control module outputs the power driving signal to the corresponding power phase output module, and controls the power phase output module to output the corresponding power signal to the connected powered device to supply power to the connected powered device.
In some possible implementation manners of the embodiment of the present application, as shown in fig. 6, the method may further include:
s601: and the main control module receives the fault information sent by the power supply control module.
In the embodiment of the present application, the fault information carries information of a faulty power phase output module in the power supply device.
S602: the main control module judges whether a power phase output module without a fault in power setting meets a redundant power supply condition or not according to the received fault information; when the power phase output module without failure does not satisfy the redundant power supply condition, step S603 is performed.
S603: and the main control module updates output setting information according to the power phase output module without faults and the redundant power supply condition.
S604: and the main control module controls the on-off state of each switch module according to the updated output setting information.
