[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on December 28, 2023, with application number 202311837228.1, and entitled “A protection circuit and its multi-configuration power supply method, device, equipment and medium”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of computer technology, and in particular to a protection circuit and a multi-configuration power supply method, device, equipment and medium thereof. Background Art

[0004] The rapid development of server data centers has led to higher safety requirements for server power supply designs, resulting in a greater number of protection circuits being incorporated into server board-level power supply designs. Current server power supply circuits often incorporate efuse (electronic fuse) protection circuits. When the system encounters issues such as overcurrent, overvoltage, or overtemperature, the efuse (electronic fuse) promptly shuts down power to protect the entire system and prevent issues like board burnout.

[0005] Efuse (electronic fuse) protection circuits often need to meet different current requirements. For example, a single efuse can meet the current requirement in each circuit. Sometimes, one or more circuits require multiple efuses to be used in parallel. To cover the higher current requirements of the protection circuit, multiple efuses need to be used in parallel.

[0006] The inventors realized that the power supply architecture of the efuse protection circuit in the prior art is usually that each circuit is independently powered and protected by one or more phases of efuse in parallel, but this solution has the problem of poor power supply efficiency in actual server configuration applications.

[0058] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0059] It should be understood that in the description of this application, unless the context clearly requires otherwise, words such as "include", "comprises", and the like throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, as "including but not limited to".

[0060] It should also be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0061] In one or more embodiments, the present application provides a protection circuit. Referring to FIG1 , the protection circuit includes: a complex programmable logic device, an electronic safety device, a voltage input terminal, a first voltage output terminal, a second voltage output terminal, and a configuration switching circuit.

[0062] Among them, the electronic safety device includes a first electronic safety device and a second electronic safety device; the voltage input end is connected to the input end of the first electronic safety device and the second electronic safety device respectively, the output end of the first electronic safety device is connected to the first voltage output end, the output end of the first electronic safety device is also connected to the input end of the configuration switching circuit, the output end of the second electronic safety device is connected to the second voltage output end, the output end of the second electronic safety device is also connected to the input end of the configuration switching circuit, the output end of the configuration switching circuit is simultaneously connected to the first voltage output end and the second voltage output end, and the complex programmable logic device is connected to the first electronic safety device and the second electronic safety device respectively; the configuration switching circuit is used to switch the power supply configuration of the electronic safety device.

[0063] For example, taking two 12V power supply protection circuits as an example, existing solutions provide completely independent protection for the two 12V power supply circuits, each protected by a separate electronic fuse. This circuit has a low current requirement and cannot be applied in scenarios with higher current requirements. In scenarios with higher current requirements, since the outputs of multiple independent electronic fuses cannot be connected together, multiple electronic fuses must be used in parallel. This results in one or more electronic fuses being unused and wasted, resulting in low utilization and inefficiency.

[0064] Specifically, in this embodiment, multiple independent electronic fuse devices can be used for independent output or directly connected together for multiple outputs, thereby improving the power supply efficiency of the electronic fuse devices.

[0065] Specifically, the CPLD is also used to read the protection circuit power supply configuration information from the computer device's mainboard memory chip via a two-wire serial bus. This allows the CPLD to obtain this information during the server's power-up phase. Specifically, it can determine whether the current protection circuit requires the independent outputs of multiple independent electronic fuses or whether the multiple outputs need to be directly connected, thereby improving the electronic fuse's power supply efficiency.

[0066] Specifically, first, in an embodiment in which each electronic fuse in the electronic fuse device operates independently, after the voltage input terminal and the first enable signal and the second enable signal emitted by the complex programmable logic device are normal, the first voltage output terminal and the second voltage output terminal both operate normally. Because the complex programmable logic device detects that the current system requires the independent output of multiple independent electronic fuses, the complex programmable logic device sends a control signal to control the configuration switching circuit to switch the electronic fuse device to the independent output of multiple independent electronic fuses. That is, the first voltage output terminal provides power according to the first electronic fuse, and the second voltage output terminal provides power according to the second electronic fuse, so that each supplies its own load.

[0067] Specifically, in an embodiment where multiple outputs of an electronic safety device are required to be connected together (operate together), after the voltage input terminal and the first enable signal and the second enable signal sent by the complex programmable logic device are normal, the first voltage output and the second voltage output are normally established. At this time, the complex programmable logic device sends a control signal to control the configuration switching circuit to switch the electronic safety device to the multiple outputs connected together (operate together). At this time, the first voltage output terminal and the second voltage output terminal jointly provide power supply protection based on the first electronic safety device and the second electronic safety device. By adopting this technical solution, when multiple independent electronic safety devices are required to output independently, the configuration switching circuit can be controlled to switch the electronic safety device to the multiple independent electronic safety devices for independent output use, and when multiple outputs are required to be directly connected together, the configuration switching circuit can be controlled to switch the electronic safety device to the multiple outputs for joint operation. This allows the multiple independent protection circuits to flexibly switch between independent operation and coordinated operation, improves the power supply efficiency of the electronic safety device, reduces the number of electronic safety devices used, optimizes the layout space of the protection circuit, and saves the design cost of the protection circuit.

[0068] In some embodiments, the power supply configuration of the electronic safety device includes at least one of the following:

[0069] Control the first voltage output end and the second voltage output end to operate independently, the first voltage output end provides power according to the first electronic fuse device, and the second voltage output end provides power according to the second electronic fuse device; or,

[0070] The first voltage output end and the second voltage output end are controlled to work together, and the first voltage output end and the second voltage output end jointly provide power according to the first electronic fuse device and the second electronic fuse device.

[0071] Specifically, when each electronic fuse in the electronic safety device operates independently, after the voltage input terminal and the first enable signal and the second enable signal emitted by the complex programmable logic device are normal, the first voltage output terminal and the second voltage output terminal both operate normally. Because the complex programmable logic device detects that the current system requires multiple independent electronic fuses to output independently, the complex programmable logic device sends a control signal to control the configuration switching circuit to switch the electronic safety device to the multiple independent electronic fuses for independent output. That is, the first voltage output terminal provides power according to the first electronic fuse, and the second voltage output terminal provides power according to the second electronic fuse, respectively supplying their respective loads for operation. When the electronic safety device requires multiple outputs to work together, after the voltage input terminal and the first enable signal and the second enable signal emitted by the complex programmable logic device are normal, the first voltage output and the second voltage output are normally established. At this time, the complex programmable logic device sends a control signal to control the configuration switching circuit to switch the electronic safety device to multiple outputs working together. At this time, the first voltage output terminal and the second voltage output jointly provide power supply protection according to the first electronic fuse and the second electronic fuse. In particular, the above embodiment only illustrates the deployment of two electronic fuses and their corresponding two voltage outputs. In actual protection circuit applications, multiple electronic fuses, such as three, four, or five, can also be deployed and used, corresponding to multiple voltage outputs. The principle is the same, namely, controlling multiple independent electronic fuses to operate independently, or controlling multiple outputs (here, multiple outputs can be all or only some of the electronic fuses in the current protection circuit) to operate together. By adopting this approach, the multiple independent protection circuits can flexibly switch between independent and coordinated operation, thereby improving the power supply efficiency of the electronic fuses, reducing the number of electronic fuses used, optimizing the protection circuit layout space, and reducing protection circuit design costs.

[0072] In some embodiments, the configuration switching circuit includes a comparison circuit, a first AND gate, a second AND gate, and a field effect transistor assembly. The output of the first electronic fuse device and the output of the second electronic fuse device are respectively connected to the input of the comparison circuit; the output of the comparison circuit is connected to the input of the first AND gate, the output of the first AND gate is connected to the output of the second AND gate, the output of the second AND gate is further connected to a complex programmable logic device, the output of the second AND gate is connected to the gate of the field effect transistor assembly, and the drain of the field effect transistor assembly is respectively connected to the first voltage output terminal and the second voltage output terminal.

[0073] Specifically, because connecting the outputs of multiple independent electronic fuses together can easily cause short circuits and other problems during startup, the configuration of a comparison circuit can prevent short circuits during startup by outputting a high-level signal after each electronic fuse output reaches a set threshold. Furthermore, the output of the comparison circuit is connected to the input of a first AND gate, the output of the first AND gate is connected to the output of a second AND gate, the output of the second AND gate is also connected to a complex programmable logic device (CPLD), the output of the second AND gate is connected to the gate of a field-effect transistor assembly, and the drain of the field-effect transistor assembly is connected to the first and second voltage outputs, respectively. The configuration of the first and second AND gates ensures that the field-effect transistor assembly is turned on only when the second AND gate outputs a high-level signal (the output of the first AND gate is a high-level signal and the CPLD also outputs a high-level signal), thereby enabling the first and second voltage outputs to function in a coordinated manner. By adopting this approach, problems such as short circuits in the output of the electronic fuse device are avoided, and the first voltage output end and the second voltage output end can be flexibly and stably switched between independent operation or collaborative operation, thereby improving the power supply efficiency of the electronic fuse device.

[0074] In some embodiments, the comparison circuit includes a first comparator and a second comparator, wherein the output of the first electronic fuse is connected to the negative input of the first comparator, the positive input of the first comparator is connected to a first reference voltage, the output of the second electronic fuse is connected to the negative input of the second comparator, and the positive input of the second comparator is connected to a second reference voltage. The output of the first comparator is connected to the input of a first AND gate, and the output of the second comparator is connected to the input of the first AND gate.

[0075] Exemplarily, the output of the first electronic fuse and the output of the second electronic fuse are connected to the negative input of the first comparator and the negative input of the second comparator, respectively, and compared with a predetermined first reference voltage and a predetermined second reference voltage, respectively (here, the first reference voltage and the second reference voltage are set to thresholds established for the corresponding electronic fuse output and are fixed values). The first reference voltage and the second reference voltage can be set according to the corresponding first electronic fuse and the second electronic fuse. The first reference voltage and the second reference voltage can be implemented by connecting a reference voltage circuit, or the voltage values ​​can be set or controlled by a complex programmable logic device. Exemplarily, if the first voltage output and the second voltage output exceed the threshold set by the corresponding comparator, a high-level signal is output by the comparator. Both comparators output high-level signals, and the high-level signal is output through the first AND gate logic control. If one of the first voltage output and the second voltage output fails to establish a voltage, the output level of the corresponding comparator is low, and it is impossible to output a high-level signal to the subsequent logic control. The arrangement of the first comparator, the second comparator and the first AND gate can avoid uneven current when the electronic fuse is started, thereby preventing the outputs of multiple electronic fuses from being connected together and causing uneven current when started, resulting in short circuits and other problems.

[0076] In some embodiments, the field effect transistor assembly includes a first field effect transistor and a second field effect transistor, the output end of the second AND gate is connected to the gate of the first field effect transistor and the second field effect transistor respectively, the source of the first field effect transistor is connected to the source of the second field effect transistor, the drain of the first field effect transistor is connected to the first voltage output end, and the drain of the second field effect transistor is connected to the second voltage output end.

[0077] In some embodiments, the first field effect transistor and the second field effect transistor are N-channel field effect transistors.

[0078] For example, the first and second field-effect transistors are connected in series in reverse order, utilizing the non-conductive nature of their body diodes to prevent the first and second voltage output terminals from being connected together when the first and second field-effect transistors are not turned on according to the normal timing control, thereby preventing a short circuit in a certain electronic fuse. This fundamentally isolates the first and second voltage output terminals. This allows each electronic fuse to operate independently even in low-current configurations.

[0079] For example, in a protection power supply circuit requiring multiple independent channels, although the first AND gate outputs a high-level signal, the complex programmable logic device detects that the multiple channels are configured to operate independently and outputs a low-level signal to the second AND gate. The second AND gate then outputs a low-level signal, preventing the first and second field-effect transistors from conducting, thereby preventing the first voltage output terminal from being connected together with the second voltage output terminal. In this case, the first and second voltage output terminals operate independently. Similarly, in a protection power supply circuit requiring multiple channels to operate together, the first AND gate outputs a high-level signal. The complex programmable logic device detects that the multiple channels are configured to operate together and outputs a high-level signal to the second AND gate. The second AND gate then outputs a high-level signal, conducting the first and second field-effect transistors. The first and second voltage output terminals are then connected together, and the first and second voltage output terminals operate together.

[0080] In one or more embodiments, when multiple independent electronic fuse devices need to be used for independent output, the configuration switching circuit can be controlled to switch the electronic fuse device to multiple independent electronic fuse devices for independent output; when multiple outputs need to be directly connected together for use, the configuration switching circuit can be controlled to switch the electronic fuse device to multiple outputs to work together, so that the multiple independent protection circuits can be flexibly switched between independent work and collaborative work, thereby improving the power supply efficiency of the electronic fuse device, saving the number of electronic fuse devices used, optimizing the protection circuit layout space, and saving the protection circuit design cost.

[0081] In one or more embodiments, the present application further provides a multi-configuration power supply method for a protection circuit, which is applied to the protection circuit provided in any of the above embodiments. The protection circuit includes a complex programmable logic device, an electronic safety device, a voltage input terminal, a first voltage output terminal, a second voltage output terminal, and a configuration switching circuit. The electronic safety device includes a first electronic safety device and a second electronic safety device. Referring to FIG. 2 , the multi-configuration power supply method for the protection circuit includes:

[0082] S1. In response to detecting that the server is powered on, obtaining protection circuit power supply configuration information through a complex programmable logic device;

[0083] S2. Sending a protection circuit power supply configuration control signal to a configuration switching circuit according to the protection circuit power supply configuration information through a complex programmable logic device;

[0084] S3. The configuration switching circuit switches to the corresponding power supply configuration according to the protection circuit power supply configuration control signal.

[0085] Specifically, the complex programmable logic device can obtain the protection circuit power supply configuration information during the server power-on phase, that is, whether the current protection circuit requires multiple independent electronic fuse devices to output independently or requires multiple outputs to be directly connected together.

[0086] Specifically, in an embodiment in which each electronic fuse in the electronic fuse device operates independently, after the voltage input terminal and the first enable signal and the second enable signal emitted by the complex programmable logic device are normal, the first voltage output terminal and the second voltage output terminal both operate normally. Because the complex programmable logic device detects that the current system requires the independent output of multiple independent electronic fuses, the complex programmable logic device sends a control signal to control the configuration switching circuit to switch the electronic fuse device to the independent output of multiple independent electronic fuses. That is, the first voltage output terminal provides power according to the first electronic fuse, and the second voltage output terminal provides power according to the second electronic fuse, so that each supplies its own load.

[0087] Specifically, in an embodiment where multiple outputs of an electronic safety device are required to be connected together (operate together), after the voltage input terminal and the first enable signal and the second enable signal sent by the complex programmable logic device are normal, the first voltage output and the second voltage output are normally established. At this time, the complex programmable logic device sends a control signal to control the configuration switching circuit to switch the electronic safety device to the multiple outputs connected together (operate together). At this time, the first voltage output terminal and the second voltage output terminal jointly provide power supply protection based on the first electronic safety device and the second electronic safety device. By adopting this method, the complex programmable logic device can obtain power supply configuration information of the protection circuit. When multiple independent electronic safety devices are required to output independently, the configuration switching circuit is controlled to switch the electronic safety device to the multiple independent electronic safety devices for independent output. When multiple outputs are required to be directly connected together, the configuration switching circuit is controlled to switch the electronic safety device to the multiple outputs for joint operation. This allows the multiple independent protection circuits to flexibly switch between independent operation and coordinated operation, improves the power supply efficiency of the electronic safety device, reduces the number of electronic safety devices used, optimizes the layout space of the protection circuit, and saves the design cost of the protection circuit.

[0088] In some embodiments, the protection circuit power supply configuration information includes at least one of the first voltage output terminal and the second voltage output terminal operating independently, and the first voltage output terminal and the second voltage output terminal operating together. Based on this, the power supply configuration includes at least one of the following:

[0089] Control the first voltage output end and the second voltage output end to operate independently, the first voltage output end provides power according to the first electronic fuse device, and the second voltage output end provides power according to the second electronic fuse device; or,

[0090] The first voltage output end and the second voltage output end are controlled to work together, and the first voltage output end and the second voltage output end jointly provide power according to the first electronic fuse device and the second electronic fuse device.

[0091] Specifically, when each electronic fuse in the electronic safety device operates independently, after the voltage input terminal and the first enable signal and the second enable signal emitted by the complex programmable logic device are normal, the first voltage output terminal and the second voltage output terminal both operate normally. Because the complex programmable logic device detects that the current system requires multiple independent electronic fuses to output independently, the complex programmable logic device sends a control signal to control the configuration switching circuit to switch the electronic safety device to the multiple independent electronic fuses for independent output. That is, the first voltage output terminal provides power according to the first electronic fuse, and the second voltage output terminal provides power according to the second electronic fuse, respectively supplying their respective loads for operation. When the electronic safety device requires multiple outputs to work together, after the voltage input terminal and the first enable signal and the second enable signal emitted by the complex programmable logic device are normal, the first voltage output and the second voltage output are normally established. At this time, the complex programmable logic device sends a control signal to control the configuration switching circuit to switch the electronic safety device to multiple outputs working together. At this time, the first voltage output terminal and the second voltage output jointly provide power supply protection according to the first electronic fuse and the second electronic fuse. It should be noted that the above implementation is only an example of deploying two electronic fuses and corresponding two voltage outputs. In actual protection circuit applications, multiple electronic fuses, such as three, four, or five, can also be deployed and used, corresponding to multiple voltage outputs. The principle is the same, namely, controlling multiple independent electronic fuses to output independently, or controlling multiple outputs (here, multiple outputs can be all or only some of the electronic fuses in the current protection circuit) to work together. By adopting this approach, multiple independent protection circuits can flexibly switch between independent and coordinated operation, thereby improving the power supply efficiency of the electronic fuses, reducing the number of electronic fuses used, optimizing the protection circuit layout space, and reducing protection circuit design costs.

[0092] In some embodiments, if the protection circuit power supply configuration information indicates that the first voltage output terminal and the second voltage output terminal work together, and the protection circuit power supply configuration control signal is a high-level signal, S3 includes:

[0093] S31. In response to the second AND gate detecting that the first AND gate outputs a high-level signal and the complex programmable logic device outputs a high-level signal, the second AND gate outputs a high-level signal to the field effect transistor component to control the first field effect transistor and the second field effect transistor to be turned on.

[0094] Specifically, in a protection power supply circuit requiring multiple outputs to work together, the first AND gate generates a high-level signal. The complex programmable logic device detects that the multiple outputs are configured to work together and generates a high-level signal to the second AND gate. The second AND gate then outputs a high-level signal, turning on the first and second field-effect transistors. The first and second voltage outputs are then connected together, and the first and second voltage outputs now work together. By employing this method, when multiple outputs need to be directly connected together, the configuration switching circuit can be controlled to switch the electronic safety device to work together. This allows multiple independent protection circuits to flexibly switch between independent and coordinated operation, improving the power supply efficiency of the electronic safety device and reducing the number of electronic safety devices used.

[0095] In some embodiments, if the protection circuit power supply configuration information indicates that the first voltage output terminal and the second voltage output terminal operate independently, and the protection circuit power supply configuration control signal is a low-level signal, S3 further includes:

[0096] S32. In response to the second AND gate detecting that the complex programmable logic device outputs a low-level signal, the second AND gate outputs a low-level signal to the field effect transistor component to control the first field effect transistor and the second field effect transistor to be non-conductive.

[0097] Specifically, the first and second field-effect transistors are connected in series in reverse order, leveraging their inherent body diodes to prevent the first and second voltage output terminals from connecting together when the first and second field-effect transistors fail to conduct according to normal timing control, thereby preventing a short circuit in a particular electronic fuse. This fundamentally isolates the first and second voltage output terminals. In a protection power supply circuit requiring multiple independent circuits, although the first AND gate outputs a high-level signal, the complex programmable logic device detects the configuration as multiple independent circuits and outputs a low-level signal to the second AND gate. The second AND gate then outputs a low-level signal, preventing the first and second field-effect transistors from conducting. This prevents the first and second voltage output terminals from connecting together, allowing the first and second voltage output terminals to operate independently. This method allows each electronic fuse to operate independently even in low-current configurations, preventing short circuits in multiple fuses and improving the stability and flexibility of the protection circuit.

[0098] In some embodiments, S3 further includes:

[0099] 101. In response to the first AND gate detecting the high-level signals output by the first comparator and the second comparator at the same time, the first AND gate outputs a high-level signal to the second AND gate;

[0100] 102. In response to the first AND gate detecting a low-level signal output by the first comparator or the second comparator, the first AND gate outputs a low-level signal to the second AND gate.

[0101] Specifically, because connecting the outputs of multiple independent electronic fuses together can easily cause short circuits and other problems during startup, a comparator circuit can be configured to output a high-level signal after each electronic fuse output reaches a set threshold, thereby avoiding the problem of short circuits during the startup of the electronic fuses. The output of the first electronic fuse and the output of the second electronic fuse are connected to the negative input of the first comparator and the negative input of the second comparator, respectively, and compared with the set first reference voltage and second reference voltage values, respectively (here, the first reference voltage and the second reference voltage are set to the threshold values ​​established for the corresponding electronic fuse output and are fixed values). If the first voltage output or the second voltage output exceeds the threshold value set by the corresponding comparator, a high-level signal is output by the comparator. Both comparators output high-level signals, and the high-level signal is output through the first AND gate logic control. If the output voltage of one of the first voltage output and the second voltage output is not established, the output level of the corresponding comparator is low, and it is impossible to output a high-level signal to the subsequent logic control. By adopting this method, the phenomenon of uneven current when the electronic fuse device is started can be avoided, thereby avoiding the problem of uneven current when multiple electronic fuse devices are connected together, causing short circuits and other problems.

[0102] In one or more embodiments, when multiple independent electronic fuse devices need to be used for independent output, the configuration switching circuit can be controlled to switch the electronic fuse device to multiple independent electronic fuse devices for independent output; when multiple outputs need to be directly connected together for use, the configuration switching circuit can be controlled to switch the electronic fuse device to multiple outputs to work together, so that the multiple independent protection circuits can be flexibly switched between independent work and collaborative work, thereby improving the power supply efficiency of the electronic fuse device, saving the number of electronic fuse devices used, optimizing the protection circuit layout space, and saving the protection circuit design cost.

[0107] In some embodiments, if the protection circuit power supply configuration information is that the first voltage output end and the second voltage output end work together, the protection circuit power supply configuration control signal is a high-level signal, and the power supply switching module is also used to respond to the second AND gate detecting that the first AND gate outputs a high-level signal and the complex programmable logic device outputs a high-level signal, and the second AND gate outputs a high-level signal to the field effect transistor component to control the first field effect transistor and the second field effect transistor to conduct.

[0108] In some embodiments, if the protection circuit power supply configuration information is that the first voltage output end and the second voltage output end operate independently, the protection circuit power supply configuration control signal is a low-level signal, and the power supply switching module is further used to respond to the second AND gate detecting that the complex programmable logic device outputs a low-level signal, and the second AND gate outputs a low-level signal to the field-effect transistor component to control the first field-effect transistor and the second field-effect transistor to not conduct.
