Among them, the power connector is connected to the first storage device connector, the power connector is also connected to the power conversion device, and the power conversion device is connected to the first storage device connector; the power connector is used to connect to the server motherboard and obtain the first voltage provided by the server motherboard to supply power to the first storage device connector; the power conversion device is used to convert the first voltage into a second voltage to supply power to the first storage device connector; the first storage device connector is used to connect to the first storage device.

[0025] Through the above power supply system, the power supply system includes a power connector, a power supply conversion device, and a first storage device connector. The power connector is connected to the first storage device connector, and the power connector is also connected to the power supply conversion device. The power supply conversion device is connected to the first storage device connector. The power connector is used to connect to the server motherboard and obtain the first voltage provided by the server motherboard to supply power to the first storage device connector. The power supply conversion device is used to convert the first voltage into a second voltage to supply power to the first storage device connector. The first storage device connector is used to connect to the first storage device. Removing the power supply conversion device from the server motherboard reduces the area of the server motherboard. Therefore, the technical problem of the too large area of the server motherboard can be solved, and the technical effect of reducing the area of the server motherboard can be achieved.

[0026] Optionally, in the embodiments of the present application, the power supply system may but is not limited to include a power connector, a power supply conversion device, and a first storage device connector.

[0027] Optionally, in this embodiment, the power connector can be, but is not limited to, one of the key components in an electronic system, mainly used to establish a stable power transmission channel between the power supply end and the electrical equipment. In servers, computers, or any device that requires external power, the power connector is responsible for receiving power from the server motherboard (or other power management unit) and delivering it to each component that needs to be powered, such as hard disk drives, SSDs (Solid State Drives), memory modules, and other storage devices. The main functions of the power connector can include, but are not limited to: Power transmission: Ensure that power is stably transmitted from the power source to each storage device, supporting the energy required for data storage and reading operations; Signal transmission: In addition to power, some power connectors can also transmit control signals for monitoring and managing the power status. For example, they can detect the presence of connected devices and control their power supply status; Safety protection: The power connector can include, but is not limited to, built-in or cooperative protection measures such as EFUSE (Electronic Fuse) to prevent damage to the system caused by overload, short circuit, or voltage fluctuations; Compatibility and standardization: The power connector can follow, but is not limited to, certain standard designs to ensure compatibility with storage devices from different manufacturers. For example, interface standards such as SATA (Serial Advanced Technology Attachment), SAS (Serial Attached Small Computer System Interface), and PCIe (Peripheral Component Interconnect Express). The power connector varies due to different application environments and functional requirements. Common types include: SATA power connector: Specifically designed for SATA hard drives, providing +5V (Volt) and +12V power, usually with a 15-pin or 7-pin design; PCIe power connector: Used for high-performance devices such as GPUs (Graphics Processing Units), providing high-power +12V power; SAS power connector: Providing power for SAS hard drives, usually more complex than the SATA power connector to support higher data rates and power requirements; USB (Universal Serial Bus) power connector: Widely used in mobile devices, external storage devices, etc., providing +5V power and data transmission; Dedicated power connector: Designed for specific types or brands of storage devices, such as the dedicated hard disk backplane power connector in some servers, which may have additional safety features or special voltage requirements.

[0028] Optionally, in the embodiments of the present application, the power connector may, but is not limited to, be used to connect to the server motherboard to obtain a first voltage provided by the server motherboard.

[0029] Optionally, in the embodiments of the present application, the power connector may also, but is not limited to, be used to connect to a first storage device connector and a power supply conversion device to provide the obtained first voltage to the first storage device connector and the power supply conversion device.

[0030] Optionally, in the embodiments of the present application, the power supply conversion device may, but is not limited to, refer to a power converter or a voltage regulator. The power supply conversion device may, but is not limited to, be a key component in the power supply system. The power supply conversion device may, but is not limited to, be responsible for converting the input power supply voltage into a voltage suitable for the operation of a specific device or circuit. The power supply conversion device may, but is not limited to, play an important role in various scenarios. Especially in the computer storage device backplane, the power supply conversion device may, but is not limited to, be used to convert the original voltage received from the server motherboard or the power supply unit into the voltage required by hard disk drives, solid state drives, or other storage devices. The power supply conversion device may, but is not limited to, not only adjust the voltage, but also provide additional functions such as current limiting, overheat protection, and short circuit protection to ensure the safe and stable operation of the entire power supply system. Optionally, there are various types of power supply conversion devices. According to their working principles and technical characteristics, they can be mainly divided into the following categories: Linear Voltage Regulator: This type of converter provides a stable power supply by continuously adjusting the output voltage. They have a simple structure but low efficiency and are usually used in scenarios where high-precision voltage regulation is required; Switching Power Supply Converter: The switching power supply converter uses switching technology to convert the input voltage into the required output voltage. This type of converter has high efficiency and is suitable for scenarios where high-efficiency conversion is required, such as power supply for hard disk backplanes in server systems. The switching power supply converter can be further divided into PWM (Pulse Width Modulation) controllers, DC-DC converters (Direct Current to Direct Current Converter), AC-DC converters (Alternating Current to Direct Current Converter), etc.; DC-DC Converter: Used to convert a DC voltage into another DC voltage, for example, converting a 12V input into a 5V or 3.3V output; AC-DC Converter: Used to convert an AC voltage into a DC voltage. In the power supply design of the server backplane, DC-DC converters in the switching power supply converter may, but is not limited to, be used because DC-DC converters can provide high-efficiency, high-density power conversion, and at the same time have good thermal management performance and flexible configuration capabilities, which are suitable for server systems with high power density and multiple hard disk drives.

[0031] Optionally, in the embodiments of the present application, the power supply conversion device may, but is not limited to, be connected to a power connector to obtain the first voltage provided by the power connector.

[0032] Optionally, in the embodiments of the present application, the power supply conversion device may also but is not limited to connecting to the first storage device connector to supply the second voltage obtained by converting the first voltage to the first storage device connector.

[0033] Optionally, in the embodiments of the present application, the first storage device connector may be but is not limited to being used to connect to the first storage device. It should be noted that the first storage device connector is connected to both the power connector and the power supply conversion device at the same time, and the voltages supplied to the first storage device connector include the first voltage and the second voltage. This is because the first storage device here requires two specifications of voltage to work properly. Specifically, most modern storage devices, especially hard disk drives and solid state drives, may but are not limited to require two different voltage levels to meet the working requirements of their internal components. For example, the motor and drive circuit of a hard disk may require a higher voltage, such as 12V, while its control and interface circuits may require a lower voltage, such as 5V. This design is to be compatible with various different characteristics of the electronic components inside the hard disk, ensuring that both the drive mechanism and the data read / write circuit of the hard disk can operate under the most suitable conditions, thereby achieving the best performance and stability.

[0034] Optionally, in the embodiments of the present application, the first storage device may be but is not limited to including: HDD (Hard Disk Drive), a hard disk drive includes execution components, such as disks and read / write heads, and the execution components usually require 12V to drive, while the control circuit may require 5V.

[0035] Optionally, in the embodiments of the present application, the first storage device may be but is not limited to including: a solid state drive. Although a solid state drive has no execution components, its internal NAND (Not AND, flash memory) flash devices and controller circuits may require different voltages. For example, some solid state drives may require 12V to provide sufficient current, while 5V is used for the controller logic circuit.

[0036] Optionally, in the embodiments of the present application, the first storage device may be but is not limited to including: SATA / SAS hard disks. SATA / SAS hard disks follow the SATA or SAS interface standards. Among them, SATA hard disks usually require both 5V and 12V at the same time; while SAS hard disks, as enterprise-level storage devices, may also require similar dual-voltage power supplies to meet the requirements of high performance and large capacity.

[0037] Optionally, in the embodiments of the present application, the first storage device connector may be but is not limited to being: a SATA connector, that is, a hard disk drive connector of the SATA interface standard, providing connections for data and two power supply voltages (usually 5V and 12V).

[0038] Optionally, in the embodiments of the present application, the first storage device connector may be, but is not limited to: a SAS / SATA Mini SAS HD connector (Miniature Serial Attached SCSI High Density Connector), a connector for high-speed SAS and SATA hard drives, which also supports data transmission and dual-voltage power supply.

[0039] Optionally, in the embodiments of the present application, the selection of the above first storage device and the first storage device connector specifically depends on the design requirements of the server system, the type and performance requirements of the storage device, as well as the power management and energy efficiency goals of the system. By adopting a power supply system with dual-voltage output capabilities, the server can flexibly support various types and specifications of storage devices while maintaining the efficient and stable operation of the system.

[0040] Optionally, in the embodiments of the present application, the server motherboard may output only one specification of voltage (i.e., the first power supply), and the power supply conversion device may not be provided on the server motherboard, which can save the setting space of the server motherboard and reduce the area of the server motherboard.

[0041] Optionally, in the embodiments of the present application, the storage devices involved in the power supply system may include, in addition to the first storage device that requires two power supply voltages, storage devices that require only one power supply voltage. For example, the storage devices involved in the power supply system may include, but are not limited to, a first storage device that requires a first voltage and a second voltage and a second storage device that requires only the first voltage, or the storage devices involved in the power supply system may include, but are not limited to, a first storage device that requires a first voltage and a second voltage and a third storage device that requires only the second voltage, or the storage devices involved in the power supply system may also include, but are not limited to, a first storage device that requires a first voltage and a second voltage, a second storage device that requires only the first voltage, and a third storage device that requires only the second voltage.

[0042] Optionally, in the embodiments of the present application, the second storage device may refer to those storage devices that require only one power supply voltage (for example, only the first voltage, which is usually 12V). These devices are designed more simply and do not require complex power management. They are mainly applied to scenarios with a single and high power demand. The second storage device may include, but is not limited to: NVMe SSD (Non-Volatile Memory Express Solid State Drive). Some NVMe SSDs only require 12V power supply and use a high-speed PCIe interface to provide extremely high data read and write speeds and low latency.

[0043] Optionally, in the embodiments of the present application, the second storage device may but is not limited to further include an HDD (Hard Disk Drive). The hard disk drive involved here may but is not limited to integrate a power conversion module internally, so only one voltage is required for power supply from the outside.

[0044] Optionally, in the embodiments of the present application, the third storage device may but is not limited to refer to those storage devices that only require a second power supply voltage (for example, 5V). Such devices may mainly rely on a lower voltage for operation, such as control circuits and interface circuits. The third storage device may but is not limited to include: an SD Card (Secure Digital Card), which is a widely used storage medium, especially in digital cameras, mobile phones, and tablet computers. They generally only require 5V power supply for data read / write control and the operation of internal logic circuits. The third storage device may also but is not limited to include a USB Flash Drive (Universal Serial Bus Flash Drive), also known as a USB drive, which usually only needs 5V power supply to work and is suitable for portable data storage and file transfer.

[0045] Optionally, in the embodiments of the present application, when the storage devices involved in the power supply system include, in addition to the first storage device, a second storage device, the power supply system may but is not limited to further include a second storage device connector. The second storage device connector may but is not limited to connect to the power connector on one hand to obtain the first voltage from the power connector, and on the other hand, the second storage device connector may but is not limited to connect to the second storage device to provide the obtained first voltage to the second storage device.

[0046] Optionally, in the embodiments of the present application, when the storage devices involved in the power supply system include, in addition to the first storage device, a third storage device, the power supply system may but is not limited to further include a third storage device connector. The third storage device connector may but is not limited to connect to the power supply conversion device on one hand to obtain the second voltage from the power supply conversion device, and on the other hand, the third storage device connector may but is not limited to connect to the third storage device to provide the obtained second voltage to the third storage device.

[0047] Optionally, in the embodiments of the present application, when the storage devices involved in the power supply system include, in addition to the first storage device, a second storage device and a third storage device, the power supply system may further include, but is not limited to, a second storage device connector and a third storage device connector. The second storage device connector may, but is not limited to, be connected to the power connector on one hand to obtain a first voltage from the power connector, and may also, but is not limited to, be connected to the second storage device on the other hand to supply the obtained first voltage to the second storage device. The third storage device connector may, but is not limited to, be connected to the power supply conversion device on one hand to obtain a second voltage from the power supply conversion device, and may also, but is not limited to, be connected to the third storage device on the other hand to supply the obtained second voltage to the third storage device.

[0048] As an alternative implementation, the first storage device connector is divided into a first number of first connector groups, and each first connector group includes a plurality of storage device connectors; the power supply conversion device includes: a first number of first power converters; the first number of first power converters correspond one-to-one with the first number of first connector groups; and the first power converter is connected to the storage device connectors in the corresponding first connector group.

[0049] Optionally, in the embodiments of the present application, the first storage device connector may, but is not limited to, include a first number of first connector groups, and each first connector group includes a plurality of storage device connectors. The division of the first connector groups means that the first storage device connectors in the entire system are not a single entity, but are divided into several groups (a first number of first connector groups). Each group may, but is not limited to, be understood as a power supply area or a set of ports, which are independent of each other and can be connected to multiple storage devices.

[0050] Optionally, in the embodiments of the present application, the power supply conversion device may, but is not limited to, include a first number of first power converters. Optionally, the first power converter may, but is not limited to, include various specifications of VR (Voltage Regulator). Optionally, these first power converters are responsible for converting the original voltage (the first voltage, such as 12V) obtained from the power connector into the second voltage (the second voltage, such as 5V) required by the first storage device.

[0051] Optionally, in the embodiments of the present application, each first power supply converter may be, but is not limited to, connected to the storage device connectors in the corresponding first connector group, that is, multiple storage devices in each first connector group may share, but are not limited to sharing, one first power supply converter. Each first power supply converter corresponds to a first connector group, ensuring that the storage devices connected to each group of storage device connectors can receive the converted power from the dedicated power supply converter. This one-to-one correspondence can achieve more refined power management and distribution, improving the stability and efficiency of the system.

[0052] Optionally, in the embodiments of the present application, in the scenario of a server or a storage system, the design of the power supply system of the present application can achieve efficient management and fault isolation of storage devices. For example, if there are 24 hard disks (first storage devices) in the system, these hard disks can be divided into multiple groups (such as 4 groups, with 6 hard disks in each group), and each group of hard disks is powered by an independent power supply converter (first power supply converter). In this way, if there is a problem with a certain power supply converter or connector group, only the hard disks in that group will be affected, and the other parts of the entire system will not be affected, thereby reducing the scope of the fault and improving the overall availability and maintainability of the system.

[0053] Through the above content, by dividing the first storage device connectors into several groups, and each group corresponding to a dedicated first power supply converter, the power supply system obtains high flexibility and manageability. This means that the system can perform independent power distribution and control for different groups of storage devices, so that when maintaining or upgrading a certain group of storage devices, there is no need to shut down or affect the normal operation of other groups, greatly improving the maintenance efficiency of the system.

[0054] As an optional implementation manner, the power supply system further includes: a first number of first power supply protection links; the first number of first power supply protection links correspond one-to-one to the first number of first power supply converters; the first power supply protection links are connected between the corresponding first power supply converter and the power connector; the first power supply protection links are used to perform power supply protection on the storage device connectors in the first connector group connected to the corresponding first power supply converter.

[0055] Optionally, in the embodiments of the present application, in addition to having the ability to supply power, the power supply system also needs to have the ability to protect the power supply, and may, but is not limited to, set up power supply protection links in the power supply system to ensure the power supply safety of the power supply system.

[0056] Optionally, in the embodiments of the present application, the power supply system may further include, but is not limited to, a first number of first power supply protection links. The number of multiple power supply protection links integrated in the power supply system is equal to the number of first power supply converters and the number of first connector groups. And the first number of first power supply protection links correspond to the first number of first power supply converters one by one, which means that each power supply converter and each group of first connector groups will be equipped with a dedicated protection link to ensure the continuity and safety of power supply.

[0057] Optionally, in the embodiments of the present application, the first power supply protection link may be connected, but is not limited to, between the corresponding first power supply converter and the power connector. The first power supply protection link may act as a goalkeeper, monitoring and controlling the current flowing from the power connector to the power supply converter to prevent any abnormal conditions (such as overload, short circuit, voltage fluctuation, etc.) from damaging the converter or further affecting the storage device.

[0058] Through the above content, by introducing the power supply protection link, the security, efficiency, and stability of the power supply system are further improved.

[0059] As an optional implementation manner, the power supply system further includes: a first electronic fuse device and a first number of first fuse-type fuse devices; the first number of first fuse-type fuse devices correspond to the first number of first power supply converters one by one; the power connector is connected to the first electronic fuse device, the first electronic fuse device is connected to the first number of first fuse-type fuse devices, each of the first fuse-type fuse devices is connected to the corresponding first power supply converter, and the first power supply protection link includes the first electronic fuse device and the corresponding first fuse-type fuse device.

[0060] Optionally, in the embodiments of the present application, the first power supply protection link may be constructed by, but is not limited to, various fuse devices.

[0061] Optionally, in the embodiments of the present application, the first electronic fuse device may be, but is not limited to, an E-Fuse (Electronic Fuse). An E-Fuse is a semiconductor device used for circuit protection. It can achieve overcurrent protection and short-circuit protection of the circuit in electronic form. E-Fuse is not a traditional fuse. Instead, it is manufactured using integrated circuit technology and can quickly respond when detecting overcurrent or short-circuit, disconnecting the circuit to protect other components in the circuit from damage. Specifically, the E-Fuse continuously monitors the flowing current. Once it detects that the current exceeds the preset threshold, the E-Fuse will immediately disconnect the circuit to prevent the current from continuing to flow, thereby protecting the circuit from overcurrent damage. Different from traditional fusing fuses, the E-Fuse can be automatically reset after the circuit overload condition is lifted, or manually reset through an external signal, without the need to replace the fuse, improving the maintainability and convenience of use of the circuit. In addition, the overcurrent threshold and action time of the E-Fuse can be flexibly adjusted through an external circuit or programming to meet different circuit protection requirements.

[0062] Optionally, in the embodiments of the present application, the first fusing fuse device may be, but is not limited to, a FUSE (fuse). A FUSE is a traditional circuit protection component that protects the circuit by fusing in the case of overcurrent. They are usually made of a low-melting-point metal wire or alloy and placed in the circuit as part of the current path. Under normal operating conditions, the fuse allows current to pass through. When the current in the circuit exceeds the rated current of the fuse, the metal wire or alloy in the fuse will melt due to overheating, thus disconnecting the circuit to prevent damage caused by overcurrent. It should be noted that the fuse needs to be replaced after fusing and cannot be automatically reset, which provides a one-time protection for the circuit.

[0063] Optionally, in the embodiments of the present application, the power supply system may also be provided with, but is not limited to, the first electronic fuse device and the first number of first fusing fuse devices to further enhance the safety and reliability of power supply. Specifically, the power connector is first connected to the first electronic fuse device, and then the first electronic fuse device is connected to a series (the first number) of first fusing fuse devices. Each first fusing fuse device corresponds to a first power supply converter, forming a protection link. This combined use method can provide dual protection. The E-Fuse is used to quickly cut off overcurrent situations while the fuse provides more persistent overcurrent protection.

[0064] Through the above content, the power supply system can not only respond quickly to overcurrent situations, but also provide more persistent protection during continuous overcurrent, ensuring the safe operation of the system even in extreme cases. In addition, the resetability of the E-Fuse also provides convenience for maintenance, while the one-time protection of the fuse ensures from another perspective that faults will not be easily overlooked and need to be replaced in a timely manner to restore the normal protection ability of the system.

[0065] As an alternative embodiment, the power supply system further includes: a first controller and a first number of first switching devices; the first number of first switching devices correspond one-to-one with the first number of first power converters; a power connector connects the first number of first switching devices, and each first switching device is connected to a corresponding first power converter; the first controller is connected to the first number of first switching devices, and the first controller is further connected to the first number of first connector groups; the first power protection link includes the first controller and the first switching devices.

[0066] Optionally, in the embodiments of the present application, the first power protection link can be constructed by, but not limited to, a combination of a logic control device and a switching device.

[0067] Optionally, in the embodiments of the present application, the first controller can be, but not limited to, a microprocessor, a microcontroller, a digital signal processor or a similar control logic unit, which can receive information from various sensors, execute a preset control algorithm, and send instructions to the first switching device to control the opening or closing of the power path.

[0068] Optionally, in the embodiments of the present application, the first switching device can be, but not limited to, various types of electronic switches, such as MOSFET (Metal Oxide Semiconductor Field Effect Transistor), IGBT (Insulated Gate Bipolar Transistor), relay or other solid-state switches. The first switching device can be, but not limited to, used to control the on / off of the power path connected to a specific power converter under the instruction of the first controller, realizing the precise distribution and management of power.

[0069] Optionally, in the embodiments of the present application, a corresponding first switching device can be provided for each power converter, and the first switching device can be, but not limited to, placed between the power connector and the first power converter, serving as a gate for the power path to control the on / off of the power according to the command of the first controller.

[0070] Optionally, in the embodiments of the present application, a first controller may be provided for the power supply system, but is not limited thereto. While the first controller is connected to all the first switching devices in the power supply system, it is also connected to all the first connector groups in the power supply system. This means that the first controller can globally monitor the status of all storage devices and accordingly determine when to turn on or off which switching device. In addition, the first controller may also, but is not limited to, implement more complex power management strategies, such as dynamically adjusting the power supply according to the load or automatically cutting off the affected power supply path when a fault is detected.

[0071] Through the above content, by introducing the first controller and the first switching devices, the power supply system achieves the purpose of intelligent and dynamic power management. It can not only quickly respond to overcurrent or abnormal situations, but also adjust the power supply strategy according to the working status of the storage devices, improve the energy utilization efficiency of the system, and at the same time ensure the safety of the devices and data.

[0072] As an optional implementation manner, the first controller is used to perform power supply protection on the storage device connectors in each first connector group by controlling the on / off of the first switching devices corresponding to each first connector group according to the fault conditions of the storage device connectors in each first connector group; the first controller is also used to perform usage control on the storage device connectors in each first connector group by controlling the on / off of the first switching devices corresponding to each first connector group according to the usage conditions of the storage device connectors in each first connector group.

[0073] Optionally, in the embodiments of the present application, the fault condition of the storage device connector may, but is not limited to, represent the fault condition of the storage device connected to the storage device connector. Similarly, the usage condition of the storage device connector may, but is not limited to, represent the usage condition of the storage device connected to the storage device connector.

[0074] Optionally, in the embodiments of the present application, the first controller may, but is not limited to, perform power supply protection on the storage device connectors in each first connector group by controlling the on / off of the first switching devices corresponding to each first connector group according to the fault conditions of the storage device connectors in each first connector group. For example, in a server cluster, the first controller regularly monitors the health status of the storage devices through a sensor network. Suddenly, the controller receives an alarm indicating that a hard disk in a certain first connector group has a short circuit fault, resulting in excessive current flow. At this time, the first controller quickly identifies the group where the fault is located and immediately sends a disconnection instruction to the first switching device corresponding to that group. The switching device responds to the signal from the controller and immediately cuts off the power supply path to prevent the fault from spreading and protecting other hard disks and system components from further damage.

[0075] Optionally, in the embodiments of the present application, the first controller is further configured to control the use of the storage device connectors in each first connector group by controlling the on / off of the first switching devices corresponding to each first connector group according to the usage of the storage device connectors in each first connector group. For example, the first controller can also but is not limited to identifying which groups of devices do not need to operate at full load at the current time point, so as to actively reduce the power output of these groups, achieving the purpose of energy conservation and emission reduction. Specifically, in the daily operation of the data center, by analyzing the access patterns of storage devices, the first controller finds that the utilization rate of most storage devices is very low during non-working hours at night. To save power and extend the device life, the first controller activates the energy-saving strategy and automatically sends a disconnection instruction to the first switching devices corresponding to the inactive groups to temporarily disconnect the power supply of these storage devices. Before the start of work the next day, the controller re-evaluates the usage of the storage devices and automatically restores the power supply to the active groups to ensure the efficient operation of the system.

As Figure 5 shown, the power supply system includes a first storage device connector, that is, Figure 5 the storage device connectors 1-16 in Figure 5 . In addition to the first storage device connector, the power supply system further includes a second storage device connector, that is,

[0102] the storage device connectors 17-24 in

[0103] As an alternative embodiment, the second storage device connector is divided into a third number of second connector groups, and each second connector group includes a plurality of storage device connectors; the power supply system further includes: a third number of fourth fuse-type protection devices; the third number of fourth fuse-type protection devices correspond one-to-one with the third number of second connector groups; the fourth fuse-type protection device is connected between the power connector and the storage device connectors in the second connector group corresponding to the fourth fuse-type protection device.

The four first connector groups are: the first connector group including storage device connectors 1 - 4, the first connector group including storage device connectors 5 - 8, the first connector group including storage device connectors 9 - 12, and the first connector group including storage device connectors 13 - 16. The second storage device connector is divided into two second connector groups, each second connector group includes 4 storage device connectors. The two second connector groups are: the second connector group including storage device connectors 17 - 20 and the second connector group including storage device connectors 21 - 24. The power supply system also includes a third quantity, namely 2 fuses (fuse 17 and fuse 18) (i.e., the fourth fuse-type protection device). Fuse 17 corresponds to the second connector group including storage device connectors 17 - 20 and fuse 17 is connected between the power connector and storage device connectors 17 - 20. Fuse 18 corresponds to the second connector group including storage device connectors 21 - 24 and fuse 18 is connected between the power connector and storage device connectors 21 - 24. Optionally, storage device connectors 1 - 16 can be but are not limited to corresponding to SATA disks that require dual power supplies of 12V (the first voltage) and 5V (the second voltage).

The first power converter can be but is not limited to a 5V VR, which is used to convert the 12V voltage to 5V voltage. The purpose of placing a FUSE (i.e., the first fuse-type protection device) at the input of each VR is that the input 12V total power supply capacity of the power connector is relatively strong. If a short-circuit fault occurs in the 5V VR, a relatively serious circuit board burning fault will occur. After adding a small-sized FUSE at the input of the 5V VR, when a short circuit occurs in the 5V VR, it can achieve open-circuit protection for the faulty 5V VR and prevent more serious faults from occurring to the power supply system and storage devices.

[0106] As an optional implementation manner, the power supply system also reserves a fourth quantity of device positions. The fourth quantity is the number of second storage device connectors; the fourth quantity of device positions corresponds one-to-one with the fourth quantity of second storage device connectors; the device positions are located between the power connector and the second storage device connectors corresponding to the device positions.

[0107] Optionally, in the embodiments of the present application, the power supply system can also but is not limited to reserve a fourth quantity of device positions between the power connector and each second storage device connector. The device positions can be but are not limited to used for setting small resistors or protection devices.

[0108] Optionally, in the embodiments of the present application, as in Figure 5In the power supply system shown, a device position can be reserved, but is not limited to, between the electronic fuse and the storage device connector 17, a device position can be reserved between the electronic fuse and the storage device connector 18, a device position can be reserved between the electronic fuse and the storage device 19, and so on. Eventually, as Figure 5 shown, 8 device positions are reserved in the power supply system.

[0109] Through the above content, by reserving device positions equal to the number of second storage device connectors, system designers can easily add protection or control devices (such as fuses, switches, etc.) at a later stage without having to perform large-scale re-design or modification of the circuit board.

[0110] As an alternative implementation, when a target resistor is installed at the device position, the target resistor is used to filter the second storage device connector corresponding to the device position. Among them, the resistance value of the target resistor is less than or equal to the target threshold; when a second electronic fuse device is installed at the device position, the second electronic fuse device is used to replace the corresponding fourth fuse-type fuse device to provide power protection for the connected second storage device connector.

[0111] Optionally, in the embodiments of the present application, a target resistor can be installed, but is not limited to, at the reserved device position to filter the second storage device connector. Among them, the resistance value of the target resistor needs to be less than or equal to the target threshold. The setting of this threshold can be, but is not limited to, based on factors such as the total impedance of the circuit, the power supply frequency, and the filtering requirements. Since too high a resistance value may introduce additional voltage drop and affect the power supply efficiency; while too low a resistance value may not effectively filter out noise. Therefore, the resistance value of the target resistor is limited within a certain range.

[0112] Optionally, in the embodiments of the present application, a second electronic fuse device can be installed, but is not limited to, at the reserved device position to provide power protection for the second storage device connector. Optionally, the second electronic fuse device can be, but is not limited to, an E-Fuse.

[0113] Through the above content, the filtering function of the target resistor has a significant effect on maintaining the stability of the power supply and improving the performance of the storage device. The filtering function of the target resistor not only ensures the purity of the power supply, reduces the impact on the storage device, but also brings economic and operational advantages to the entire power supply system by extending the device life and improving data integrity.

[0114] As an alternative embodiment, the power supply system further includes: a switch integrated circuit and a plurality of second power converters; the plurality of second power converters are connected in parallel between the power connector and the switch integrated circuit; alternatively, the plurality of second power converters are cascaded between the power connector and the switch integrated circuit; the plurality of second power converters are configured to convert a first voltage into a power supply voltage required by the plurality of switch integrated circuits.

Optionally, the second power converter can be but is not limited to including various specifications of VR (Voltage Regulator).

[0117] Optionally, in the embodiments of the present application, the input of each second power converter can first pass through a fuse type FUSE, and then pass through an input inductor to the input end of the second power converter. The input of the second power converter designs an input capacitor according to the magnitude of the output current, such as placing a barrel-shaped electrolytic capacitor and multiple ceramic multilayer capacitors.

[0118] Optionally, in the embodiments of the present application, in Figure 5 the power supply system shown, the plurality of second power converters include a second power converter 1, a second power converter 2, and a second power converter 3. These three second power converters can be but is not limited to being connected in parallel between the power connector and the switch integrated circuit. Specifically, the second power converter 1 can be but is not limited to converting a first voltage of 12V into a voltage of 1.8V required by the switch integrated circuit, the second power converter 2 can be but is not limited to converting a first voltage of 12V into a voltage of 1.2V required by the switch integrated circuit, and the second power converter 3 can be but is not limited to converting a first voltage of 12V into a voltage of 0.9V required by the switch integrated circuit.

As Figure 6As shown, the power supply system may but is not limited to include three second power converters, namely, second power converter A, second power converter B, and second power converter C. These three second power converters may but are not limited to be cascaded between the power connector and the switch integrated circuit. Specifically, second power converter A may but is not limited to convert the first voltage of 12V into the 1.8V voltage required by the switch integrated circuit, second power converter B may but is not limited to convert the supply voltage of 1.8V into the 1.2V voltage required by the switch integrated circuit, and second power converter C may but is not limited to convert the supply voltage of 1.2V into the 0.9V voltage required by the switch integrated circuit. It can be seen that the second power converter in the cascaded form has a smaller voltage conversion span compared to the second power converter in the parallel form, and the options for the second power converter in the cascaded form are easier.

[0120] Through the above content, by introducing the switch integrated circuit and multiple second power converters, the efficiency, stability, and safety of the power supply system are significantly improved. Whether in a parallel or cascaded configuration, it can optimize the power conversion process and achieve intelligent power management.
