[0026] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0027] Figure 1 This is a schematic diagram of a power distribution unit according to an embodiment of the present disclosure. Considering the high-temperature operating environment of loads such as servers, the power distribution unit 10 needs to ensure the reliability of power supply to loads such as servers in high-temperature environments. However, existing power distribution units 10 are prone to aging in high-temperature environments, resulting in a failure to provide reliable power to servers. This embodiment of the present disclosure provides a power distribution unit 10 that can continuously supply power from the power supply 100 to loads such as servers, improving the reliability of power supply from the power distribution unit 10 to loads such as servers. It should be noted that the load can be a cluster of servers, and multiple power distribution units 10 can be set up. Each power distribution unit 10 can include multiple switch modules 3. As needed, each power distribution unit 10 connected to each server in the cluster can be configured to have the structure and function of the power distribution unit 10 provided in this embodiment.
[0028] See Figure 1 The power distribution unit 10 provided in this embodiment specifically includes: an input terminal 1, which is used to connect the power distribution unit 10 to the power supply 100; a calculation unit 2, which is connected to the input terminal 1 and is used to generate a control command when the power supply 100 is connected to the input terminal 1; and at least two switch modules 3, which are connected to the calculation unit 2 and the power supply 100, and are used to turn on in response to the control command, and after the switch module 3 is turned on, the power supply 100 and the load remain in a conducting state.
[0029] Specifically, input terminal 1 is used to connect power distribution unit 10 to power supply 100, and input terminal 1 may include power supply 100 input cable. Power supply 100 can be an upstream power supply 100 such as municipal power supply 100 or generator power supply 100.
[0030] Computing unit 2 can be a variety of general-purpose and / or special-purpose processing components with processing and computing capabilities. Some examples of computing unit 2 include, but are not limited to, microcontrollers (MCUs), central processing units (CPUs), graphics processing units (GPUs), various special-purpose artificial intelligence (AI) computing chips, various computing units running machine learning model algorithms, digital signal processors (DSPs), and any suitable processors, controllers, microcontrollers, etc.
[0031] Furthermore, a computing unit 2 is configured to generate control commands when a power supply 100 is connected to the input terminal 1. The computing unit 2 provided in this embodiment can communicate with the switch module 3. The control commands are used to control the switching module 3 to turn on or off.
[0032] At least two switch modules 3 are provided, and the number of switch modules 3 can be set according to the load requirements. Switch modules 3 can be switching components with holding functions, such as magnetic latching relays, contactors, etc. The conduction state of switch modules 3 on the same power distribution unit 10 is controlled by the control signal of the computing module. The control terminal of switch module 3 is connected to the computing unit 2, the first terminal of switch module 3 is connected to the power supply 100, and the second terminal of switch module 3 is connected to the load. Switch modules 3 are used to conduct in response to control commands, and after switch modules 3 are conducted, the power supply 100 and the load remain in a conducting state. The function of maintaining the conducting state after switch modules 3 are conducted avoids unnecessary power outages caused by aging of switch modules 3, and better ensures that the power distribution unit 10 provides reliable power supply to the load.
[0033] Furthermore, when the power distribution unit 10 includes multiple switching modules 3 that all need to be powered on, the control signal can control the multiple switching modules 3 to be powered on simultaneously, or the control signal can control the multiple switching modules 3 to be powered on at different times, without any limitation.
[0034] The technical solution of this application embodiment, by introducing a computing unit 2 and a switching module 3 connected to the input terminal 1, can generate control commands when the power supply 100 is connected to the input terminal 1, and turn on the switching module 3 according to the control commands. After the switching module 3 is turned on, the power supply 100 and the load remain in a conductive state, thereby improving the power supply reliability of the power distribution unit 10 to the load. This configuration solves the problem that existing power distribution units are prone to aging due to operating in high-temperature environments, affecting the power supply reliability of loads such as servers. It lays the foundation for avoiding the problem of low power supply reliability of the power distribution unit 10 and provides a new approach to improving the power supply reliability of the power distribution unit 10 to loads such as electrical equipment.
[0035] Figure 2 This is a schematic diagram of another power distribution unit provided according to an embodiment of the present disclosure. Based on the above embodiment, see [link to other embodiments]. Figure 2As an optional embodiment of this disclosure, the power distribution unit 10 in this embodiment further includes a power driving module 4. The first end of the power driving module 4 is connected to the power supply 100, the second end of the power driving module 4 is connected to the switch module 3, and the third end of the power driving module 4 is connected to the computing unit 2. The power driving module 4 is used to convert the voltage of the power supply 100 into a first voltage, which is used to power the switch module 3 and the computing unit 2. The amplitude of the first voltage is less than the amplitude of the voltage of the power supply 100.
[0036] Specifically, the power supply driver module 4 can be an AC-DC module. The first terminal of the power supply driver module 4 is connected to the power supply 100. The power supply driver module 4 can step down the voltage of the power supply 100 to the voltage required by the computing unit 2 and the switching module 3, or convert the AC power supply 100 to DC voltage, as needed. The second terminal of the power supply driver module 4 is connected to the switching module 3, which may include control circuits such as the drive unit 31. The second terminal of the power supply driver module 4 is used to output the power supply voltage required by the control circuits such as the drive unit 31 of the switching module 3. The third terminal of the power supply driver module 4 is connected to the computing unit 2. The power supply driver module 4 is used to convert the voltage of the power supply 100 to the voltage required by the computing unit 2 and output it to the computing unit 2 through the third terminal of the power supply driver module 4 to supply power to the computing unit 2.
[0037] The technical solution of this application embodiment improves the voltage level range applicable to the power distribution unit 10 by introducing a power drive module 4 connected between the power supply 100 and the computing unit 2, and between the power supply 100 and the switching module 3. Based on the above embodiment, it achieves power supply requirements for the computing unit 2 and the switching module 3 at different voltage levels, improves the working stability and environmental adaptability of the power distribution unit 10, solves the problem of low power supply reliability of the power distribution unit 10 to electrical equipment and other loads in the prior art, lays the foundation for avoiding the problem of low power supply reliability of the power distribution unit 10, and provides a new approach to improving the power supply reliability of the power distribution unit 10 to electrical equipment and other loads.
[0038] Figure 3 This is a schematic diagram of another power distribution unit provided according to an embodiment of the present disclosure. Based on the above embodiments, see [link to other embodiments]. Figure 3 As an optional embodiment of this disclosure, the power distribution unit 10 in this embodiment includes a switching module 3 comprising a driving unit 31 and a switching unit 32; the driving unit 31 is connected to the computing unit 2 and the switching unit 32 respectively, and the switching unit 32 is connected between the power supply 100 and the load; the driving unit 31 is used to generate a driving signal according to a control command; the switching unit 32 is used to turn on according to the driving signal, and after the switching unit 32 is turned on, the switching unit 32 remains in the on state.
[0039] Specifically, the driving unit 31 can be a driving circuit composed of switching transistors, etc. The control terminal of the driving unit 31 is connected to the computing unit 2, and the output terminal of the driving unit 31 is connected to the switching unit 32. The switching unit 32 can include a coil and contacts. The coil of the switching unit 32 is connected to the output terminal of the driving unit 31, and the contacts of the switching unit 32 are turned on or off according to the driving signal output by the driving unit 31. When the contacts of the switching unit 32 are on, the power supply 100 supplies power to the load through the input terminal 1, and the contacts of the switching unit 32 can remain in the on state. Even if the coil of the switching unit 32 fails, the switching unit 32 can still maintain the connection between the power supply 100 and the load, further improving the power supply reliability of the power distribution unit 10.
[0040] The technical solution of this application improves the power supply reliability of the power distribution unit 10 by introducing a drive unit 31 connected to the computing unit 2 and a switch unit 32 connected to the drive unit 31, the power supply 100, and the load respectively. Based on the above embodiment, a drive signal is generated in response to the control command of the computing unit 2, and the switch unit 32 is controlled to turn on according to the drive signal. After the switch unit 32 is turned on, it remains in the on state. This solves the problem of low power supply reliability of the power distribution unit 10 to electrical equipment and other loads in the prior art, laying the foundation for avoiding the problem of low power supply reliability of the power distribution unit 10 and providing a new approach to improving the power supply reliability of the power distribution unit 10 to electrical equipment and other loads.
[0041] Based on the above embodiments, see below. Figure 3 As an optional embodiment of this disclosure, the switching unit 32 of the power distribution unit 10 in this embodiment includes: a magnetic latching relay, the coil of the magnetic latching relay is used to be energized according to the received drive signal, the normally open contact of the magnetic latching relay is used to be attracted when the coil is energized, and the normally open contact is used to maintain the attracted state through the permanent magnet of the magnetic latching relay.
[0042] Specifically, magnetic latching relays feature low power consumption, stable operation, low temperature rise, and long service life. Since the operating state of a magnetic latching relay does not rely on the coil power supply 100, the contacts are held by a permanent magnet. Even after the power supply 100 to the drive unit 31 fails, the switching unit 32 remains on, ensuring that loads such as servers connected to the magnetic latching relay contacts do not lose power due to the failure of the drive power supply 100.
[0043] The technical solution of this application embodiment introduces a magnetic latching relay. The coil of the magnetic latching relay is energized according to the received drive signal, and the normally open contact of the magnetic latching relay is attracted when the coil is energized. The normally open contact is held in the attracted state by the permanent magnet of the magnetic latching relay. This ensures that even if the power supply 100 of the drive unit 31 fails, the normally open contact of the magnetic latching relay remains conductive, thereby guaranteeing that loads such as servers connected to the normally open contact of the magnetic latching relay will not lose power due to the failure of the drive power supply 100, thus improving the power supply reliability of the power distribution unit 10. Based on the above embodiment, a voltage distribution unit with lower power consumption and higher power supply reliability is achieved. This solves the problem that the power distribution unit 10 is prone to aging in high-temperature environments, affecting the power supply reliability of loads such as servers. It lays the foundation for avoiding the problem of low power supply reliability of the power distribution unit 10 and provides a new approach to improving the power supply reliability of the power distribution unit 10 to electrical equipment and other loads.
[0044] Based on the above embodiments, see below. Figure 3 As an optional embodiment of this disclosure, the switch module 3 in this embodiment includes N magnetic latching relays, where N is a positive integer greater than or equal to 2; the calculation unit 2 is used to generate a first control instruction, which is used to control the first magnetic latching relay to conduct; the calculation unit 2 is also used to delay for a preset time period of N-1, and generate an Nth control instruction, which is used to control the Nth magnetic latching relay to conduct.
[0045] Specifically, each power distribution unit 10 may include N magnetic latching relays, for example, it may include a first magnetic latching relay to an Nth magnetic latching relay. The calculation unit 2 is used to generate a first control command, delay for a first preset time period, generate a second control command, and so on, delaying for an N-1 preset time period to generate an Nth control command. The first control command is used to control the first magnetic latching relay to conduct, the second control command is used to control the second magnetic latching relay to conduct, and so on, with the Nth control command controlling the Nth magnetic latching relay to conduct.
[0046] When the power distribution unit 10 is powered on for the first time, the power drive module 4 operates, and the computing unit 2 is powered on. After the computing unit 2 is powered on, it can generate a first control command after a preset delay as needed. The first control command acts on the first drive unit, which can respond to the first control command by generating a first drive signal. The first magnetic latching relay is powered on according to the first drive signal, and its normally open contact closes and remains closed, thereby powering on the load connected to the first magnetic latching relay.
[0047] The calculation unit 2 delays for a first preset time period and generates a second control command. The second control command acts on the second drive unit, which can respond to the second control command by generating a second drive signal. The second magnetic latching relay is energized according to the second drive signal, and its normally open contact closes and remains closed, thereby energizing the load connected to the second magnetic latching relay.
[0048] Similarly, calculation unit 2 generates the Nth control command after a preset time interval of N-1. The Nth control command acts on the Nth drive unit, which can respond to the Nth control command by generating the Nth drive signal. The Nth magnetic latching relay is energized according to the Nth drive signal, and its normally open contact closes and remains closed, thereby energizing the load connected to the Nth magnetic latching relay.
[0049] The technical solution of this application embodiment introduces a switching module including N magnetically latched relays. A calculation unit 2 generates a first control command, delays for a first preset time period, generates a second control command, and so on, delaying for an N-1 preset time period to generate the Nth control command. This technical solution achieves reliable power supply to multiple loads connected to the same power distribution unit 10. Based on the above embodiment, time-sharing power supply to loads connected to the same power distribution unit 10 is achieved. This configuration reduces inrush current in the circuit where the power distribution unit 10 is located, reduces the impact on the miniature circuit breaker on the power supply 100 side, and better avoids malfunction of the miniature circuit breaker. It further improves the power supply reliability of the power distribution unit 10 to loads such as servers, laying the foundation for avoiding the problem of low power supply reliability of the power distribution unit 10 and providing a new approach to improving the power supply reliability of the power distribution unit 10 to loads such as electrical equipment.
[0050] Figure 4 This is a schematic diagram of another power distribution unit provided according to an embodiment of the present disclosure. Based on the above embodiments, and in conjunction with... Figure 3 and Figure 4 As an optional embodiment of this disclosure, the power distribution unit 10 in this embodiment further includes: a plurality of slots 5, the slots 5 being connected between the switching unit 32 and the load, and the slots 5 being used to connect the load.
[0051] Specifically, one end of the normally closed contact of the switch unit 32 is connected to the power supply 100, and the other end is connected to the load via slot 5. Slot 5 can be connected to the power supply 100 interface of the load, such as electrical equipment. Slot 5 is generally female, while the power supply 100 interface of the load, such as electrical equipment, is generally male. The shape of slot 5 can be set as needed, as long as it can be electrically connected to the power supply 100 interface of the load, such as electrical equipment, and no restrictions are imposed here.
[0052] The technical solution of this application improves the ease of connection between the power distribution unit 10 and the load by introducing a slot 5 for connecting the load. Based on the above embodiments, the load and the power distribution unit 10 can be directly plugged in and out, improving the adaptability of the power distribution unit 10. This lays the foundation for avoiding the problem of complex installation and wiring of the power distribution unit 10, and provides a new approach to promoting the widespread application of the power distribution unit 10.
[0053] Based on the above embodiments, see below. Figure 3 and Figure 4 As an optional embodiment of this disclosure, the power distribution unit in this embodiment further includes: a plurality of conductive connecting pieces 7, the conductive connecting pieces 7 being connected between the switch unit 32 and the slot 5; the conductive connecting pieces 7 and the switch unit 32 are arranged in a one-to-one correspondence; each conductive connecting piece 7 is connected to at least one slot 5.
[0054] Specifically, the conductive connecting piece 7 may include a metal conductive piece, such as a copper conductor, aluminum conductor, silver conductor, or alloy conductor. When the conductive connecting piece 7 is provided with a slot 5, this arrangement allows each switching unit 32 to be connected to a single load through a slot 5.
[0055] When the conductive connecting piece 7 is provided with multiple slots 5, since each slot 5 can be connected to a load, this arrangement allows multiple loads to be connected to each conductive connecting piece 7, so that each switching unit 32 can distribute power to multiple loads at the same time, further improving the load-carrying capacity of the power distribution unit 10.
[0056] The technical solution of this application embodiment introduces a conductive connecting piece 7 connecting the switching unit 32 and the slot 5. The conductive connecting piece 7 is configured in a one-to-one correspondence with the switching unit 32, and each conductive connecting piece 7 is connected to at least one slot 5. This improves the load-carrying capacity of the power distribution unit 10, and each switching unit 32 controls at least one load to be turned on. Based on the above embodiment, this achieves the goal of maximizing the number of loads connected to a power distribution unit 10 while ensuring that the loads connected to the power distribution unit 10 are kept in a conducting state through magnetic latching relays. This further improves the power supply reliability of the power distribution unit 10 and solves the problem of the large number of slots 5 required by loads such as cluster servers for the power distribution unit 10.
[0057] Based on the above embodiments, see below. Figure 4 As an optional embodiment of this disclosure, the power distribution unit 10 in this embodiment further includes: a housing, the housing including a shell and a cavity enclosed by the shell; a slot 5 is disposed on the shell, and the computing unit 2, the switching module 3 and the power drive module 4 are disposed in the cavity.
[0058] Specifically, the housing is made of insulating material. The shape of the housing can be customized as needed; multiple slots 5 can be located on the surface of the housing, either on the same surface or on different sides, without any limitation. The housing of the power distribution unit 10 can form a cavity, within which a computing unit 2, a switching module 3, and a power drive module 4 are housed. The housing is used to fix and protect the computing unit 2, the switching module 3, and the power drive module 4 housed within the cavity.
[0059] The technical solution of this application embodiment, by introducing a housing, can form a cavity in which the computing unit 2, the switching module 3, and the power drive module 4 are disposed, thereby improving the connection stability between the modules of the power distribution unit 10 and avoiding the risk of short circuits between the modules of the power distribution unit 10 and the load. Based on the above embodiment, the power supply reliability of the power distribution unit 10 is further improved.
[0060] Based on the above embodiments, see below. Figure 4 As an optional embodiment of this disclosure, the housing in this embodiment includes multiple through holes, and the computing unit 2, the switch module 3 and the power drive module 4 are pluggable and respectively disposed in the corresponding through holes.
[0061] Specifically, the computing unit 2 can be configured as a hot-swappable structure, and can be plugged into the corresponding through-hole of the housing via a connector. The switch module 3 can also be configured as a hot-swappable structure, and can be plugged into the corresponding through-hole of the housing via a connector. The power drive module 4 is configured as an independent module, connected to the power supply 100 via a connector, such as a pin structure, and plugged into the corresponding through-hole of the housing. This configuration achieves the effect of reliably installing the computing unit 2, switch module 3, and power drive module 4, and also allows for direct hot-swapping replacement of the computing unit 2, switch module 3, and / or power drive module 4 via spare modules when they fail due to aging or other reasons, thus facilitating the installation and maintenance of the power distribution unit 10.
[0062] Furthermore, the switching module 3 includes a drive unit 31 and a switching unit 32. When the switching unit 32 includes a magnetic latching relay, both the drive unit 31 and the magnetic latching relay can be configured to be hot-swappable. This configuration allows for direct hot-swapping replacement of the drive unit 31 and / or the magnetic latching relay if either fails. When only the drive unit 31 fails, the replacement of the drive unit 31 does not affect the continuous conduction state of the magnetic latching relay, thereby further improving the power supply reliability of the power distribution unit 10 and facilitating maintenance while reducing repair costs. When the magnetic latching relay fails, it can be replaced via hot-swapping. Only the load connected to the failed magnetic latching relay needs to be de-energized; other magnetic latching relays on the power distribution unit 10 where the failed relay is located remain on, further improving the power supply reliability of the power distribution unit 10.
[0063] Furthermore, the power distribution unit 10 may also include an indicator module connected to the power drive module 4. The indicator module is used to indicate the health or operating status of the power drive module 4. The indicator module may include an indicator light or a buzzer, or other audible and visual alarm device. This configuration facilitates timely alarm in case of a malfunction in the power drive module 4.
[0064] The technical solution of this application embodiment reduces the maintenance cost of the power distribution unit 10 by introducing a housing with multiple through holes, in which the computing unit 2, the switching module 3, and the power drive module 4 are pluggably disposed respectively. Based on the above embodiment, live maintenance of the power distribution unit 10 is achieved, further improving the power supply reliability of the power distribution unit 10. This lays the foundation for avoiding the problem of low power supply reliability of the power distribution unit 10 and provides a new approach to improving the power supply reliability of the power distribution unit 10 to the load.
[0065] Based on the above embodiments, see below. Figure 4 As an optional embodiment of this disclosure, the computing unit 2 in this embodiment is further configured to: generate a control command after a preset time delay when the power supply 100 is de-energized; wherein the control command is used to trigger the normally open contact of the magnetic latching relay to open.
[0066] Specifically, when power supply 100 is interrupted for an extended period, calculation unit 2 delays for a preset time period and generates a control command. This control command triggers the normally open contact of the magnetic latching relay to open, disconnecting power supply 100 from the load. This configuration allows the magnetic latching relay to open after power supply 100 is interrupted, preventing arcing of the relay contacts and effectively extending its lifespan. When power supply 100 is restored, calculation unit 2 of power distribution unit 10, based on the initial power-on configuration strategy, controls each magnetic latching relay on power distribution unit 10 to start power-on in batches after a preset time delay. This avoids inrush current in the circuit where power distribution unit 10 is located, reducing the impact on the miniature circuit breaker on the power supply 100 side.
[0067] Furthermore, when power supply 100 experiences a brief interruption, power drive module 4 will experience output instability. However, the magnetic latching relay does not rely on the power supply module 4 for power and remains in the engaged state, providing power to the load immediately once power supply 100 stabilizes.
[0068] The technical solution of this application improves the power supply reliability of the power distribution unit 10 to loads such as servers by introducing a control command generated after a preset time delay when the power supply 100 is de-energized, thereby triggering the normally open contact of the magnetic latching relay to open. Based on the above embodiments, it effectively avoids the malfunction of miniature circuit breakers, further improving the power supply reliability of the power distribution unit 10 to loads such as servers. This lays the foundation for avoiding the problem of low power supply reliability of the power distribution unit 10 and provides a new approach to improving the power supply reliability of the power distribution unit 10 to loads such as electrical equipment.
[0069] Figure 5 This is a flowchart illustrating a power distribution method according to an embodiment of the present disclosure. This embodiment is applicable to situations where a power distribution unit distributes power to a load. The power distribution method provided in this embodiment can be executed by a power distribution unit, and the power distribution method includes:
[0070] S501, Connect the power distribution unit to the power supply via the input terminal.
[0071] S502. When power is connected to the input terminal through the computing unit, control commands are generated.
