[0062] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that, in the embodiments of the present application, many technical details are presented in order to make the readers better understand the present application. However, the technical solutions claimed by the present application can be implemented even without these technical details and based on various changes and modifications of the following embodiments. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific embodiments of the present application, and the embodiments can be combined and referenced with each other without contradiction.

[0063] It should be noted that, in the embodiments of the present application, before the overall technical solution is described, in order to make those skilled in the art better understand the present application, therefore, the related art is described.

[0064] First, Faraday's law of electromagnetic induction: this law indicates that the induced electromotive force in a closed loop is proportional to the rate of change of the magnetic flux passing through the loop. Although it is stated that the phenomenon caused by the change of magnetic flux, but through Maxwell's equations can be known that the changing magnetic field will also produce an electric field, thereby indirectly leading to the generation of induced electromotive force.

[0065] Second, eddy current effect: in an alternating electric field, if there is a conductor (such as a metal block) placed in the electric field, the change of the electric field will produce a vortex-shaped induced current in the conductor, i.e. eddy current. These eddy currents will produce their own magnetic field, which interacts with the magnetic field of the original electric field, resulting in energy loss and heating.

[0066] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0067] With the development of artificial intelligence technology, the power supply system of data centers has brought many challenges. In order to improve the energy density and improve the power supply efficiency, more and more data centers adopt the whole cabinet centralized power supply. Correspondingly, the server also changes to use the power supply clip to obtain the input current from the power supply busbar.

[0068] The input AC mains is converted to DC to supply the whole cabinet. Compared with the traditional UPS (uninterruptible power supply) power supply mode, the battery used for energy storage and protection can be directly placed in front of the server without the need for DC / AC conversion again, improving energy efficiency. And the voltage of the DC power can also be increased to 380V, further improving energy utilization efficiency.

[0069] Common centralized power supply whole cabinet usually adopts the following power supply mode:

[0070] The power is passed to one or more power supply busbars, and the server takes power through the power supply clip on the back panel. Each power supply busbar is responsible for supplying power to multiple servers.

[0071] The advantages of this power supply mode are:

[0072] (1) Space utilization: more server nodes can be placed in a unit area, with high space utilization, and great advantages in data computing density.

[0073] (2) Power density: high power density, can realize a substantial increase in power. Multiple nodes share power supply cells, optimizing power output.

[0074] (3) Overall power consumption: under the action of centralized power supply and centralized heat dissipation, the overall power consumption has an advantage over general servers.

[0075] (4) Operation and maintenance: high integration, simple and fast deployment method, convenient operation and maintenance.

[0076] But centralized power supply also has certain shortcomings that restrict its development. In addition to high environmental requirements and high initial investment, the main problem of whole cabinet centralized power supply is its safety. First of all, under centralized power supply, multiple server nodes access the same power supply, and when the power supply fails, it will affect multiple servers.

[0077] At the same time, when a node fails, it may also affect the power supply, causing other nodes to fail. Secondly, in actual operation and maintenance, it often needs to extract or insert a single node alone, but in order not to affect the work of other nodes, hot plug operation needs to be performed when the power supply is working.

[0078] Because the power supply clip and the power supply bus are in pressure contact, current and voltage instability and arc phenomenon are extremely easy to occur in hot plug, which damages the plug node and may even affect other nodes and power supply. Therefore, how to avoid the safety problem of hot plug is a threshold for promoting the further popularization of centralized power supply.

[0079] Referring to FIG. 1, a structural schematic diagram of a server power supply protection system provided in an embodiment of the present application is shown:

[0080] The server power supply protection system comprises an input circuit and a charging circuit;

[0081] The input circuit is provided with an input switch 101;

[0082] The charging circuit is provided with an energy storage device 102 and a bypass switch 103;

[0083] The server 104 is connected with the power supply clip 105 based on the input circuit through the input switch 101;

[0084] The input switch 101 is configured to control the server 104 to access or disconnect from the input circuit;

[0085] The server 104 is connected with the power supply clip 105 based on the charging circuit through the energy storage device 102 and the bypass switch 103;

[0086] The bypass switch 103 is configured to control the server 104 and the energy storage device 102 to access or disconnect from the charging circuit.

[0087] Hot swap function is a very important technology in the field of servers, which allows certain components to be plugged in, replaced or upgraded during system operation without shutting down the entire system. This greatly improves the usability, maintainability of the system, while reducing downtime.

[0088] The power supply clip, as a key component in the hot swap function, provides stable power supply for the hot swap device and ensures that no sparks or short circuits occur during plugging and unplugging, thereby protecting the device and system.

[0089] The power supply clip usually adopts a spring type or magnetic type design, which can include spring type power supply clip, magnetic type power supply clip, etc.

[0090] Spring type power supply clip:

[0091] When the device is inserted, the spring will press the contact point to the connector of the device to establish a reliable electrical connection.

[0092] When the device is unplugged, the spring force is weakened, the contact point is disconnected, and the power supply is cut off.

[0093] Magnetic type power supply clip:

[0094] The magnetic force attracts the contact to the connector of the device, achieving connection.

[0095] When the device is unplugged, the magnetic force disappears, and the contact is separated.

[0096] According to different devices and application scenarios, the power clip can be divided into multiple types:

[0097] Power module power clip: mainly used for hot plug of server power module.

[0098] Hard disk power clip: used for hot plug of hard disk drive.

[0099] Network card power clip: used for hot plug of network card.

[0100] Other device power clip: used for other devices supporting hot plug, such as fans, expansion cards, etc.

[0101] The design requirements of the power clip should have the following characteristics.

[0102] Reliability: ensure that the contact can be connected and disconnected stably and reliably during the device insertion and removal process, prevent poor contact or spark generation.

[0103] Safety: with overcurrent and overvoltage protection functions to prevent device damage.

[0104] Compatibility: able to support different types of devices and interfaces.

[0105] Long life: still maintain good performance after multiple insertions and removals.

[0106] The importance of the power clip in the server can include:

[0107] Improve system availability: allow replacement of faulty components during system operation, reduce downtime.

[0108] Simplify system maintenance: can quickly replace or upgrade devices, reduce maintenance costs.

[0109] Enhance system scalability: allow flexible addition or removal of devices to meet changing needs.

[0110] As a key component of hot plug technology, the design and performance of the power clip directly affect the reliability and availability of the entire system. By understanding the working principle, types and design requirements of the power clip, we can better understand the important role of hot plug technology in the server field.

[0111] In specific implementation, the embodiment of the present application can parallel a bypass as a charging circuit beside the input circuit, thereby realizing the protection effect in the hot plug process.

[0112] The main device of the charging circuit is an energy storage device, which may include, but is not limited to, a battery, a super capacitor, and the like, and the available energy of the energy storage device does not necessarily support the normal operation of the server for a period of time, but only needs to ensure that the node can complete the shutdown action or the normal power-down action of devices such as hard disks and intelligent network cards.

[0113] The charging circuit of the energy storage device is between the power clip and the input switch.

[0114] In some embodiments of the present application, the server power supply protection system includes a current limiting protection device 106 for the charging circuit;

[0115] The current limiting protection device is arranged between the energy storage device and the power clip.

[0116] By connecting a current limiting protection device such as a resistor, a fuse, or the like, the energy storage device can be protected from damage.

[0117] A complex programmable logic device is a kind of digital integrated circuit. It allows users to program the internal logic circuit according to their needs, thereby realizing various digital logic functions.

[0118] Features of a complex programmable logic device:

[0119] Programmability: The internal logic circuit can be changed through programming, which is very flexible.

[0120] Parallelism: There are multiple logic blocks inside, which can work in parallel to improve processing speed.

[0121] Reconfigurability: It can be programmed multiple times, making it easy to modify and upgrade circuit design.

[0122] The bypass switch is used to control whether the energy storage device is connected to the charging circuit. The control of the bypass switch can be controlled by the back-end complex programmable logic device or the standby function of the normally operating server, so that the energy storage device can be connected to the node in the normally operating state of the server.

[0123] In some embodiments of the present application, the server power supply protection system includes a detection device for determining whether the power clip is inserted stably.

[0124] For example, before hot insertion, the input switch and the bypass switch are both in the off state. During hot insertion, the detection device is used to check whether the insertion is stable. When it is confirmed that the power clip is inserted, the input switch is turned on, the server node starts the power-on sequence, and starts to work normally. At the same time, the bypass switch is opened, and the energy storage device is connected to the server power supply protection system.

[0125] When hot plugging is performed, the plugging action is detected by detecting the insertion depth of the power clip or voltage fluctuation, at which time the input switch is turned off; while the bypass switch is in the open state at this time, the server operating system performs the power-down process. When the operating system completes the power-down operation, the bypass switch is turned off, and waits for the next hot insertion process. The energy storage device plays a buffering role in the entire operation process.

[0126] The device for controlling the input switch includes, but is not limited to, a hot plug control module, a power clip insertion depth detection module, a chassis travel switch, and the like, which can detect the start of the hot plug action.

[0127] The control of the bypass switch includes, but is not limited to, a server node complex programmable logic device, a standby electric voltage divider, and the like, which can determine the normal operation of the node.

[0128] The states of the input switch and the bypass switch are as follows:

[0129] In the embodiments of the present application, the server power supply protection system includes an input circuit and a charging circuit; the input circuit is provided with an input switch; the charging circuit is provided with an energy storage device and a bypass switch; the server is connected with the power clip through the input switch based on the input circuit; the input switch is configured to control the server to access or disconnect from the input circuit; the server is connected with the power clip through the energy storage device and the bypass switch based on the charging circuit; the bypass switch is configured to control the server and the energy storage device to access or disconnect from the charging circuit, thereby avoiding the damage of the server caused by the failure of centralized power supply, and protecting the safety of hardware and data.

[0130] On the basis of the above-mentioned embodiments, variant embodiments of the above-mentioned embodiments are proposed. It should be noted that, in order to make the description brief, only the differences from the above-mentioned embodiments are described in the variant embodiments.

[0131] In some embodiments of the present application, the input switch is a first semiconductor field effect transistor, the bypass switch is a second semiconductor field effect transistor, the server power supply protection system includes a first controller for the input switch and a second controller for the bypass switch, and the first controller is a travel switch of the server.

[0132] The first controller is configured to control the input switch to make the server access or disconnect from the input circuit;

[0133] The second controller is configured to control the bypass switch to make the server and the energy storage device access or disconnect from the charging circuit.

[0134] A MOSFET, short for Metal-Oxide-Semiconductor Field-Effect Transistor, is a semiconductor device widely used in electronic circuits. It is called a MOSFET because its structure primarily consists of a metal (gate), an oxide (insulating layer), and a semiconductor (channel).

[0135] The working principle of a MOSFET is based on the control of the conductivity of a semiconductor by an electric field. By applying a voltage to the gate, the conductivity of the channel can be changed, thereby controlling the flow of current.

[0136] N-type MOSFET: When the gate voltage is higher than the source voltage by a certain value, a channel is formed, and electrons can flow from the source to the drain, turning on the MOSFET.

[0137] P-type MOSFET: When the gate voltage is lower than the source voltage by a certain value, a channel is formed, and holes can flow from the source to the drain, turning on the MOSFET.

[0138] Characteristics of MOSFETs:

[0139] High input impedance: There is an oxide insulating layer between the gate and the channel, so the input current is very small.

[0140] Simple structure: Compared to bipolar transistors, MOSFETs have a simpler structure and are easier to integrate.

[0141] Good switching characteristics: MOSFETs can work like switches, with very low resistance when conducting and very high resistance when cut off.

[0142] Easy to integrate: MOSFETs are the foundation of modern integrated circuits and can be integrated on a large scale in processors.

[0143] Applications of MOSFETs

[0144] MOSFETs have a wide range of applications; they can be found in almost all electronic devices, for example:

[0145] Digital circuits: These constitute basic circuits such as logic gates and flip-flops.

[0146] Analog circuits: used as amplifiers, switches, oscillators, etc.

[0147] Power electronics: used in switching power supplies, motor drives, etc.

[0148] Integrated circuit: The basic unit that makes up various integrated circuit processors.

[0149] MOSFETs are very important semiconductor devices, characterized by their simple operating principle, superior performance, and wide range of applications. With the continuous development of integrated circuit technology, the role of MOSFETs in electronic circuits will become increasingly crucial.

[0150] Limit switches in servers primarily serve a protective and control function. They are typically installed on the moving parts of the server chassis or equipment, and trigger corresponding control signals by detecting the movement of these parts.

[0151] The main functions of limit switches in servers:

[0152] Security protection:

[0153] To prevent equipment damage: When the moving parts of the equipment (such as hard drive drawers, optical drive trays, etc.) move beyond the safe range, the limit switch will trigger an alarm or cut off the power to prevent equipment damage.

[0154] To prevent data loss: During the installation of the hard drive drawer, the limit switch ensures that the hard drive is fully inserted, preventing errors during data transfer.

[0155] Status monitoring:

[0156] Device status detection: By detecting the status of limit switches, the operating status of the device can be understood, such as whether the hard drive is inserted or whether the optical drive caddy is closed.

[0157] System Management: The server operating system can perform corresponding system management operations based on the signals from the limit switches, such as automatically mounting hard drives and ejecting optical drives.

[0158] Control the operation of the equipment:

[0159] Triggering device action: When the limit switch detects that the device is in a specific position, it can trigger the corresponding control signal to control the start, stop or other actions of the device.

[0160] Linking with other devices: Limit switches can be linked with other devices to achieve more complex control functions.

[0161] Common application scenarios of limit switches in servers:

[0162] Hard drive drawer: Checks if the hard drive is fully inserted to prevent data transfer errors.

[0163] Optical drive tray: Checks whether the optical drive tray is closed to prevent disc damage.

[0164] Chassis door: Check if the chassis door is closed to prevent dust from entering.

[0165] Fan module: Check if the fan module is installed correctly to ensure system heat dissipation.

[0166] Types of travel switches:

[0167] Mechanical travel switch: simple structure, high reliability.

[0168] Photoelectric travel switch: high precision, fast response.

[0169] Magnetic travel switch: non-contact, long life, not affected by the environment.

[0170] As a simple mechanical or electronic component, the travel switch plays an important role in servers. It not only improves the safety of the equipment, but also simplifies system management and improves the reliability of the system.

[0171] Referring to FIG. 2, FIG. 2 is a structural diagram of another server power protection system provided in the embodiments of the present application;

[0172] The input switch of the server power protection system is a first semiconductor field effect transistor 201, the bypass switch is a second semiconductor field effect transistor 203, and the first controller is a travel switch 207 of a server 204. The travel switch can be a press switch placed behind the cabinet, connected to the G stage of the first semiconductor field effect transistor and the second semiconductor field effect transistor respectively. When the power clip is inserted into the fully fitted position, the travel switch is in contact with the whole cabinet and is pressed into place.

[0173] In some embodiments, the travel switch is configured to send a first high-level signal to the first semiconductor field effect transistor after the detection device determines that the power clip is inserted stably, control the input switch to close, and enable the server to access the input circuit;

[0174] The second controller is configured to send a second high-level signal to the second semiconductor field effect transistor after the server accesses the input circuit, so that the server and the energy storage device access the charging circuit.

[0175] In a specific implementation, when the power clip 205 is inserted into the fully fitted position, the travel switch is in contact with the whole cabinet and is pressed into place. At this time, the travel switch outputs a continuous high-level signal to the G stage of the first semiconductor field effect transistor, so that the first semiconductor field effect transistor is turned on.

[0176] The server 204 node receives the input current and starts normal work, and the complex programmable logic device starts normal operation, outputs a high level to the G stage of the second semiconductor field effect transistor, so that the battery 202 can access the input circuit. The charging circuit of the battery 202 is between the power clip 205 and the first semiconductor field effect transistor 201, and a resistor and a diode 206 are placed for current limiting and preventing the battery from discharging the power bus.

[0177] In some embodiments of the present application, the travel switch is configured to stop sending the first high-level signal to the first semiconductor field effect transistor after the power clip is hot pulled out, control the input switch to be off, and disconnect the server from the input circuit;

[0178] The energy storage device is configured to supply power to the server after the power clip is hot pulled out;

[0179] The server is configured to perform a power-off shutdown operation after the power clip is hot pulled out;

[0180] The second controller is configured to stop sending the second high-level signal to the second semiconductor field effect transistor after the server performs the power-off shutdown operation, and disconnect the server and the energy storage device from the charging circuit.

[0181] Exemplarily, when hot pulling is performed, the travel switch 207 is first disconnected from the whole cabinet, and stops outputting a high-level signal to the first semiconductor field effect transistor 201. The first semiconductor field effect transistor 201 is immediately turned off.

[0182] However, due to the presence of the battery 202, the back-end complex programmable logic is still working normally, and the operating system starts the executable shutdown power-off work. The battery capacity can support it to complete the entire power-off process. When the complex programmable logic stops working due to battery power or self-stopping, the G stage of the second semiconductor field effect transistor also loses the high level, and is turned off.

[0183] The input switch is a first semiconductor field effect transistor, the bypass switch is a second semiconductor field effect transistor, the server power supply protection system includes a first controller for the input switch, and a second controller for the bypass switch, the first controller is a travel switch of the server; the first controller is configured to control the input switch to connect or disconnect the server to the input circuit; the second controller is configured to control the bypass switch to connect or disconnect the server and the energy storage device to the charging circuit. The travel switch is configured to send a first high-level signal to the first semiconductor field effect transistor after the detection device determines that the power clip is inserted stably, control the input switch to close, and connect the server to the input circuit; the second controller is configured to send a second high-level signal to the second semiconductor field effect transistor after the server is connected to the input circuit, so that the server and the energy storage device are connected to the charging circuit. The travel switch is configured to stop sending the first high-level signal to the first semiconductor field effect transistor after the power clip is hot pulled out, control the input switch to open, and disconnect the server from the input circuit; the energy storage device is configured to supply power to the server after the power clip is hot pulled out; the server is configured to perform a power-off shutdown operation after the power clip is hot pulled out; and the second controller is configured to stop sending the second high-level signal to the second semiconductor field effect transistor after the server performs the power-off shutdown operation, so that the server and the energy storage device are disconnected from the charging circuit.

[0250] The hot plug module is configured to control the server access to the input circuit in response to receiving the control instruction.

[0251] When hot insertion is performed, the power clip charges the super capacitor through the fuse and current-limiting resistor as a protection device, and the enable signal of the hot plug module is provided as a control instruction by the output voltage division of the super capacitor, which can be adjusted specifically.

[0252] When the super capacitor is charged to a certain threshold, the enable input of the hot plug module is determined to be high, the module is turned on, and the system starts to power on.

When the hot plug control module detects voltage fluctuation, i.e. hot pulling out is performed, the circuit is immediately turned off.

[0259] The super capacitor is connected to the input circuit through a Zener diode; the breakdown voltage of the Zener diode can be selected to be less than the difference between the lowest input voltage allowed by the server node and the normal input voltage.

[0260] When the voltage difference between the input circuit and the super capacitor is less than the breakdown voltage of the Zener diode, the super capacitor discharges to provide energy for the server node to make the server execute a power-off process, thereby protecting data and devices.

[0261] In the embodiment of the application, the input switch is a hot plug module, and the bypass switch is a Zener diode.
