[0015] It should be noted that in the description of the present application, the terms "include", "comprise" or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article or device including a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. The terms "first", "second", etc. in the present application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0016] To enable those skilled in the art of the present technology to better understand the solution of this application, the following further detailed description of this application will be given in conjunction with the accompanying drawings and specific implementation manners.

[0017] In combination with the specific application environment architecture or specific hardware architecture on which the execution of the power supply method depends, the specific application environment architecture or specific hardware architecture will be described herein.

[0018] An embodiment of this application provides a power supply system, and the power supply system will be described in detail in combination with the execution process of the power supply system.

[0019] Figure 1 It is a schematic structural diagram of a power supply system provided by an embodiment of this application. As Figure 1 shown, the power supply system includes: a control component, a first power supply component, and a second power supply component. The control component is electrically connected to the first power supply component and the second power supply component respectively, and the first power supply component and the second power supply component are electrically connected to the load respectively; The control component refers to a central control unit integrating logic processing capabilities (such as a programmable logic controller (PLC), a micro control component, or an application-specific integrated circuit), which has functions of data acquisition, logical judgment, and instruction sending, and is used to coordinate the start, stop, and switching of multiple power supply components. The power supply requirement of the load is a specific power supply method required by the load, covering different types and different combination forms such as AC power supply, DC power supply, and energy storage power supply, which specifically depends on the operating requirements of the load and its overall power supply components. The power supply component is a power supply structure, usually including power distribution, redundancy setting, switching mechanism, etc. The power supply component includes, but is not limited to, a power supply architecture.

[0020] The control component switches the first power supply component and / or the second power supply component to supply power to the load according to the power supply requirement of the load.

[0021] The power supply demand of the load refers to the type of power input that the load currently needs to match, specifically including: one-way AC power supply and one-way DC power supply. For example, a combination of one-way 380V AC mains power supply and one-way 240V DC power supply; two-way DC power supply. For example, two independent 240V DC power supplies (such as photovoltaic DC power supply and battery DC power supply) for power supply. The power supply component of the load is a specific power supply component matched according to the mapping relationship. For example, the first power supply component: a power supply unit that supports dual-mode input of "DC power supply" and "AC power supply", outputs stable DC power through an internal conversion module, and is compatible with a hybrid transmission module for AC and DC; the second power supply component: a dual-path conversion unit dedicated to processing DC input with different power quality, and can select the optimal conversion path according to the input DC power quality (such as voltage fluctuation, ripple factor). The power supply demand is at least one of the first power supply demand of one-way AC power supply and one-way DC power supply and the second power supply demand of two-way DC power supply.

[0022] Based on the power supply demand of the load, the control component determines the power supply component corresponding to the power supply demand of the load according to the pre-established mapping relationship between the power supply demand and the power supply component, and sends a start instruction to the power supply component of the load, so that the power supply component of the load supplies power to the load.

[0023] The pre-established mapping relationship between the power supply demand and the power supply component refers to the precise corresponding relationship constructed by technicians between various power supply demands and the power supply components most suitable for providing such power supply demands through a large number of experiments and data analyses based on the power supply planning and design of the load before the power supply system is put into use. The pre-established mapping relationship between the power supply demand and the power supply component is stored in the storage unit of the control component in the form of a data table or a structured configuration file, providing a basis for the rapid decision-making of the control component.

[0024] The control component maintains a real-time communication connection with the load, obtains its current power supply demand through the signal sent by the load, including key parameters such as the required voltage, current, frequency, and power supply type, so as to clarify the power supply demand of the load. When the control component determines the power supply demand of the load, the control component immediately accesses the mapping relationship table in its own storage unit, and quickly matches the corresponding power supply component according to the query condition of the power supply demand of the load. For example, if the power supply demand of the load is one-way AC power supply and one-way DC power supply, the control component will find the pre-set power supply component in the mapping table that can provide these two types of electrical energy at the same time. After determining the power supply component of the load, the control component generates a start instruction containing the power supply component of the load and sends it to the power supply component through a dedicated communication line. After receiving the start instruction, the internal control circuit of the power supply component immediately triggers the corresponding power conversion and transmission device, and starts to transmit stable power to the load according to the requirements of the start instruction to ensure the normal operation of the load.

[0025] The control component can flexibly select multiple power supply components according to the different power supply requirements of the load. Whether it is based on AC power supply or DC power supply, the control component can provide corresponding support to adapt to various application scenarios.

[0026] The first power supply component includes: a first DC conversion module for converting DC power supply into direct current and transmitting the direct current to the load; and an AC conversion module for converting AC power supply into direct current and transmitting the direct current to the load.

[0027] The first power supply component refers to a composite power supply system designed specifically for simultaneously accessing AC and DC power, including the following core modules: The first DC conversion module: The link for processing DC input signals, including filtering, voltage adjustment, and isolation circuits; The AC conversion module: The link for processing AC input signals, including rectification, filtering, and voltage conversion circuits.

[0028] The first power supply requirement for one-way AC power supply and one-way DC power supply refers to the hybrid power supply mode required by the load corresponding to the first power supply requirement, which requires using one-way AC power supply (such as 380V / 50Hz mains power) and one-way DC power supply (such as 240V DC backup power) simultaneously or alternatively. AC power supply refers to the AC power source introduced from the external power grid or AC generator, which usually needs to be rectified and converted into DC for use by the load. DC power supply refers to the directly input DC power source (such as a solar cell array, battery pack, or high-voltage DC power distribution system), which can be adapted to DC loads such as servers without rectification.

[0029] The hardware composition of the first power supply component can include the first DC conversion module and the AC conversion module. The first DC conversion module can include, but is not limited to, an input interface: connecting the positive and negative poles of the DC power source; an anti-interference module: suppressing high-frequency noise by an inductor-capacitor (LC) filter; a voltage adjustment module: an adjustable buck circuit for stabilizing the input DC voltage to 48V (allowing a fluctuation of plus or minus 2%); an isolation diode: preventing current from flowing back to the DC source. The AC conversion module can include, but is not limited to: an input interface: connecting the live wire, neutral wire, and ground wire of the AC power source (such as a three-phase socket); an AC conversion module: a full-bridge rectification circuit for converting AC into pulsating DC; an anti-interference module; a filtering circuit: smoothing the pulsating waveform with electrolytic capacitors. A voltage adjustment module: an isolated buck converter for outputting a stable DC voltage; an isolation diode: connected in parallel with the DC path to ensure that the DC power source is preferentially used when there is a dual input. However, it should be clear that this statement is not intended to limit the composition of the first power supply component to only be composed of the above components, and the first power supply component can also be composed of other components.

[0030] The power supply logic and control process of the first power supply component can be AC-DC parallel power supply or single power supply. Among them, for AC-DC parallel power supply, when both AC and DC inputs are valid, the diode of the first DC conversion module conducts, and the diode of the AC conversion module is turned off due to reverse bias, and the DC power supply is preferentially used. If the DC input is abnormal (such as the voltage drops below 44V), the diode of the AC conversion module automatically conducts and switches to AC power supply. For single power supply, when only AC or DC is connected, the diode of the corresponding module conducts and directly supplies power to the load.

[0031] For easy understanding, an example is provided. When the mains power is normal + standby DC is online, the first DC conversion module steps down the 240V input to 48V and outputs it to the load through a diode; the AC conversion module is in a hot standby state (the rectifier module keeps working but the diode is cut off). When the mains power is interrupted, the first DC conversion module detects the failure of the AC input (through a voltage sensor) and immediately increases the output power to full load to ensure seamless switching.

[0032] However, it should be clear that this statement is not intended to limit the power supply logic and control process of the first power supply component to only the above process, and it can also be other processes.

[0033] By designing independent power modules for AC and DC power supplies respectively, and adopting reasonable circuit connections and parameter configurations, the first power supply component can ensure that stable AC and DC power can still be provided to the load under the condition of external power supply fluctuations or partial equipment failures. For example, when the external AC power supply has a voltage drop, the AC conversion module can adjust the voltage. At the same time, the first DC conversion module can continue to provide stable DC power to ensure that the equipment relying on DC power is not affected, thereby enhancing the reliability of the load power supply and reducing the risk of service interruption caused by power supply problems.

[0034] The second power supply component includes: a second DC conversion module and a third DC conversion module. The second power supply component switches the second DC conversion module or the third DC conversion module to supply power to the load according to the power quality of the DC power supply; among them, the second DC conversion module and the third DC conversion module are used to convert DC power supplies with different power qualities into direct current.

[0035] The second power supply component is a power supply system designed specifically to provide two-way DC power supply. The second power supply component includes multiple power conversion and transmission modules, which can receive external DC power and distribute and convert it into two-way DC power that meets the load requirements. It is a key facility for realizing two-way DC power supply. The second power supply requirement for two-way DC power supply refers to one of the power supply methods required by the load, including two-way DC power supply. For example, some servers (i.e., loads) in certain data centers require two independent DC power supplies to improve the reliability and redundancy of power supply. When one-way DC power supply fails, the other way can continue to supply power to the equipment to ensure the uninterrupted operation of the data center.

[0036] The hardware composition of the second power supply component can include a first circuit switching module, a second DC conversion module, and a third DC conversion module. The first circuit switching module can include, but is not limited to, an input interface: two-way DC input terminals, supporting reverse polarity protection; a power quality detection circuit: a voltage sensor that collects voltage, current, and ripple data of the two-way input in real time; a switching switch: a two-way Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) array, whose conduction state is controlled by a micro-control component. The second DC conversion module (main path) can include, but is not limited to, an anti-interference module: a common mode choke to suppress electromagnetic interference; a voltage adjustment module to adapt the main DC input to the set voltage (such as 48V) for output; an isolation diode: to prevent reverse current injection from the standby circuit. The third DC conversion module (standby path) can be a boost circuit: a boost converter that boosts the standby DC input to the set voltage (such as 48V); a priority control logic: to judge whether the main path voltage is lower than a preset threshold (such as 44V) based on the first circuit switching module. However, it should be clear that this statement is not intended to limit the composition of the first power supply component and the second power supply component to only be composed of the above components. The first power supply component and the second power supply component can also be composed of other components.

[0037] The power supply logic and control process of the second power supply component can be main DC power supply or main DC fault switching. Among them, the main DC power supply can be that the first circuit switching module detects that the main DC voltage ≥ 45V and the ripple ≤ 3%, controls the MOSFET to conduct the main path, and the second DC conversion module outputs 48V to the load; the third DC conversion module is in a hot standby state (the boost circuit is on standby and the diode is cut off). The main DC fault switching can be that if the main DC voltage drops below 44V (such as insufficient output of the photovoltaic panel on a cloudy day), the switching module immediately disconnects the main path MOSFET and conducts the standby path MOSFET. The third DC conversion module starts the boost circuit, boosts the 192V battery input to 48V, and outputs it through the diode.

[0038] For ease of understanding, an example is provided. When the main DC power is stable, the PV array outputs 240V DC, which is stepped down to 48V by the second DC conversion module and directly supplies power to the server cabinet; the standby battery remains in a floating charge state. When the main DC power suddenly fails and the PV input is interrupted due to a fault, the switching module switches to the third DC conversion module within 5ms, and the boost circuit ensures stable output voltage, enabling the data center load to switch without perception.

[0039] However, it should be clear that this statement is not intended to limit the power supply logic and control process of the second power supply component to only the above process, and it can also be other processes.

[0040] By providing two-way DC power supply, the redundancy of power supply is enhanced. When one-way DC power supply fails, the other way can continue to supply power to the load, reducing the risk of service interruption caused by power supply problems and improving the reliability of load power supply.

[0041] In practical applications, the load may have energy storage power supply. When the load has energy storage power supply, the first power supply component needs to be improved. The hardware composition improvement of the first power supply component can include a DC conversion module, an AC conversion module, and an energy storage component. The DC conversion module can include but is not limited to a DC transmission module: processing high-quality DC input (such as 240V ± 5%), directly stepping down to the set voltage (such as 48V) for output. An anti-interference module and a voltage adjustment module: processing low-quality DC input (such as voltage fluctuation of plus or minus 20%), stabilizing the output through a buck-boost converter circuit. The AC conversion module can include but is not limited to a rectification and filtering circuit: converting alternating current into smooth direct current; an isolated DC / DC (Direct Current / Direct Current Converter) converter: stepping down 300V DC to 48V DC. The battery power transmission module can include but is not limited to a bidirectional DC / DC circuit: charging the battery normally (constant voltage / constant current mode), and boosting the output when power is off (such as 192V battery → 48V output). An open circuit protection switch: a MOSFET array controls the battery on and off to prevent over-discharge or short-circuit risks. However, it should be clear that this statement is not intended to limit the composition of the first power supply component to only the above components, and the first power supply component can also be composed of other components.

[0042] For ease of understanding, an example is provided. Scenario 1: Mains power + DC is normal, the AC power supply is rectified and converted to 48V output, and the DC power supply is in a hot standby state (the second circuit switching module keeps the DC input path closed but the diode is cut off). Scenario 2: Mains power is interrupted + DC is abnormal, the control component detects that the AC power fails and the DC input voltage < 200V, immediately closes the MOSFET of the energy storage power supply path, boosts to 48V for power supply, and sends an alarm signal at the same time.

[0043] However, it should be clear that this statement is not intended to limit the power supply logic and control process of the first power supply component to only the above process, and it can also be other processes.

[0044] Through the integration of the two power supply components, the load can obtain a stable power supply under different power demands and power failures. Even if one of the power supply types fails, the energy storage site or other power supply types can ensure the continuous operation of the load and avoid the load shutdown or data loss caused by power interruption.

[0045] Through this application, since the control component switches the first power supply component and / or the second power supply component to supply power to the load according to the power supply demand of the load; the first power supply component includes: a first DC conversion module for converting DC power supply into direct current and transmitting the direct current to the load; and an AC conversion module for converting AC power supply into direct current and transmitting the direct current to the load; the second power supply component includes: a second DC conversion module and a third DC conversion module, and the second power supply component switches the second DC conversion module or the third DC conversion module to supply power to the load according to the power quality of the DC power supply; wherein, the second DC conversion module and the third DC conversion module are used to convert DC power supplies with different power qualities into direct current. The control component switches the first power supply component and / or the second power supply component to supply power to the load according to the power supply demand of the load, so that the first power supply component and the second power supply component adapt to different power supply demands of the load, improving the compatibility of the power supply components. Therefore, the technical problem of poor compatibility of the power supply components can be solved, and the technical effect of improving the compatibility of the power supply components can be achieved.

[0046] In some embodiments, for better understanding of the first power supply component, as Figure 2 shown, Figure 2 is a schematic structural diagram of a first power supply component provided by an embodiment of the present application. The first power supply component includes: a first DC conversion module and an AC conversion module; The first DC conversion module is electrically connected to the DC power supply, the AC conversion module is electrically connected to the AC power supply, and the first DC conversion module and the AC conversion module are respectively electrically connected to the load; The first DC conversion module transmits the direct current in the DC power supply to the load; The AC conversion module transmits the alternating current in the AC power supply to the load.

[0047] The first DC conversion module refers to a power transmission device used to transmit DC power supply to a load. This module is responsible for obtaining power from the DC power supply and delivering it to the load, ensuring the stability and reliability of the DC power. The AC conversion module refers to a power transmission device used to transmit AC power supply to a load. This module is responsible for obtaining power from the AC power supply and delivering it to the load, ensuring the stability and reliability of the AC power.

[0048] When configuring the first power supply component for a load, the power requirements and redundancy requirements of the load are first considered. The architecture mainly includes: The first DC conversion module: Transmits the power in the DC power supply (such as a battery pack or a DC power system) to the load through a DC transmission module. This module is electrically connected to the DC power supply and adjusts the voltage through a dedicated power converter (such as a DC converter) to ensure stable power supply. The AC conversion module: Transmits the AC power supply to the load through AC power supply. This module is electrically connected through the AC power supply to ensure stable and adjustable power and meet the power requirements of the load. The AC power is stepped down or stepped up to a suitable voltage level by a transformer and then supplied to the load.

[0049] The DC power supply transmits power to the load through the first DC conversion module. First, the DC power supply provides power for the DC power supply through a battery or a rectifier. Then, the first DC conversion module transmits the stable DC power to the power distribution unit in the load. The AC power supply transmits power to the load through the AC conversion module. Through the power transmission system of the AC power supply, the AC power enters the load from the power grid and provides power suitable for the load demand through a device for adjusting the voltage (such as a transformer).

[0050] The first power supply component can achieve redundant switching between DC and AC power supplies. When a fault occurs in the AC power, the system will automatically enable the DC power module to provide power; on the contrary, when a problem occurs in the DC power supply, the AC power module can replace the DC power supply and continue to supply power. Through the power management system, the system can flexibly adjust the power supply source according to the load situation to ensure uninterrupted operation of the load. The power management system monitors each module in the first power supply component in real time. The system will dynamically adjust the power supply method and power distribution according to the real-time load demand of the load. For example, in the case of a light load, the system may give priority to using the DC power supply to avoid energy waste; while in the case of a heavy load, the system will give priority to calling the AC power supply to provide more power support.

[0051] By configuring the first DC conversion module and the AC conversion module, it is ensured that the load can still obtain stable power supply when a power supply failure occurs. Whether it is a DC power supply or an AC power supply failure, the backup power supply will be automatically started to ensure continuous and stable operation of the load.

[0052] In some embodiments, please continue to refer to Figure 2, the first DC conversion module includes: a first anti-interference module and a first voltage adjustment module; The first anti-interference module is electrically connected to the DC power supply and the first voltage adjustment module respectively, and the first voltage adjustment module is electrically connected to the load; The first anti-interference module is used to perform anti-interference processing on the DC power supply and transmit the DC power supply after the anti-interference processing of the first anti-interference module to the first voltage adjustment module; The first voltage adjustment module is used to adjust the voltage of the DC power supply after the anti-interference processing of the first anti-interference module to a preset voltage to obtain direct current, and transmit the direct current to the load.

[0053] The first anti-interference module is a filtering module for suppressing high-frequency noise, surges and electromagnetic interference in the DC input, and usually consists of, but is not limited to, inductors, capacitors and transient voltage suppressors. For better understanding of the anti-interference module, as Figure 3 shown, Figure 3 is a schematic structural diagram of an anti-interference module provided by an embodiment of the present application. The anti-interference module can be an electromagnetic interference (EMI) and buffer circuit. The EMI and buffer circuit can be an EMI filter circuit composed of a capacitor and a common-mode inductor. The common-mode interference in the high-voltage DC or AC voltage is suppressed by the magnetic path cancellation in the common-mode inductor.

[0054] The first voltage adjustment module is a voltage stabilization module that adjusts the input DC voltage to a target value (such as 48V), and supports buck, boost or buck-boost topologies. For better understanding of the voltage adjustment module, as Figure 4 shown, Figure 4 is a schematic structural diagram of a voltage adjustment module provided by an embodiment of the present application. The voltage adjustment module can be a non-isolated voltage stabilization circuit of a DC / DC circuit. The non-isolated voltage stabilization circuit of the DC / DC circuit can be Figure 4 the Buck bucking circuit in. The Buck bucking circuit is used for bucking. The Buck bucking circuit can contain two metal oxide semiconductor (MOS) transistors, an inductor and a capacitor. By controlling the on / off of the MOS transistors, the charging or freewheeling time of the inductor is controlled to achieve non-isolated bucking in a wide voltage range.

[0055] The first diode can be a unidirectional conduction device (such as a Schottky diode), which is used to prevent the current from flowing back to the DC source and at the same time realize the priority control of multiple power supply paths. The preset voltage can be the output voltage value set according to the load demand (such as 48 plus or minus 1%), and it needs to adapt to the power consumption specifications of servers, network devices, etc.

[0056] The first anti-interference module is located between the DC power supply and the first voltage regulation module. Its main function is to perform anti-interference processing on the incoming direct current, removing electromagnetic interference and noise that may affect power stability. The first anti-interference module is usually composed of anti-interference components such as inductors and capacitors, ensuring a pure current through filtering and suppression measures. The first voltage regulation module regulates the direct current from the first anti-interference module. Its working principle is to regulate the voltage by using a voltage regulator (such as a DC / DC converter) to ensure that the voltage meets the standards required by the load. The first voltage regulation module can be a DC / DC non-isolated voltage-stabilized converter. The first diode is installed at the output end of the first voltage regulation module, and its main function is to ensure that the current flows only in one direction, thus preventing damage to the power system when the current flows in the reverse direction.

[0057] When the DC power supply transmits power through the first DC transmission module, first, the direct current enters the first anti-interference module. The first anti-interference module suppresses noise and filters interference on the input current, ensuring that the power signal is not affected by external factors. The anti-interference current is transmitted through the first anti-interference module to the first voltage regulation module. The first voltage regulation module regulates the DC voltage after anti-interference processing. According to the power demand of the load, the first voltage regulation module adjusts the voltage to a preset standard value. The regulated voltage is transmitted to the first diode. The first diode outputs the regulated DC voltage to the load, ensuring that the current flows only in one direction, thus avoiding damage to the power system caused by reverse current flow. Through the above processing, the voltage of the direct current is regulated and safely transmitted to the power supply system of the load through the diode. The whole process ensures the stability, reliability, and safety during the power transmission process.

[0058] Through redundant design, precise voltage regulation, and anti-interference measures, it is possible to effectively reduce the load failure rate caused by power fluctuations or interference, thereby reducing the maintenance workload and cost and increasing the service life of the load.

[0059] In some embodiments, please continue to refer to Figure 2 , the AC conversion module includes: a second anti-interference module, an AC conversion module, and a second voltage regulation module; The second anti-interference module is electrically connected to the AC power supply and the AC conversion module respectively, and the AC conversion module is electrically connected to the second voltage regulation module; The second anti-interference module is used to perform anti-interference processing on the AC power supply and transmit the AC power supply after anti-interference processing by the second anti-interference module to the AC conversion module; The AC conversion module is used to convert the AC power supply after anti-interference processing by the second anti-interference module into a second direct current and transmit the second direct current to the second voltage regulation module; The second voltage adjustment module is used to adjust the voltage of the second direct current to a preset voltage to obtain direct current and transmit the direct current to the load.

[0060] The AC conversion module refers to the AC power input processing link, which is composed of an anti-interference, rectification, voltage adjustment, and isolation circuit and is used to convert AC power into stable DC power suitable for the load. The second anti-interference module refers to a filter circuit used to suppress high-frequency noise, surges, and electromagnetic interference (EMI) in the AC input, and usually consists of, including but not limited to, a common-mode inductor, a capacitor, and a gas discharge tube.

[0061] The AC conversion module is a rectification module (such as a full-bridge rectification circuit) that converts AC power into DC power and outputs a pulsating DC waveform. The AC conversion module can be a power factor correction (PFC) rectification boost circuit. For better understanding of the AC conversion module, as Figure 5 shown, Figure 5 is a schematic structural diagram of an AC conversion module provided by an embodiment of the present application. Taking a single-phase 220V AC input as an example, the AC conversion module being a PFC rectification boost circuit can be Figure 5 the Boost-type rectification boost circuit in. This rectification boost circuit first uses a rectifier bridge and a large capacitor to cooperate to convert the input AC voltage into DC, and further boosts the voltage to 400V / 800V DC regulated voltage through a Boost circuit. In addition, the AC conversion module shown in Figure 6 can also be used. Figure 6 is a schematic structural diagram of another AC conversion module provided by an embodiment of the present application. Figure 6 The AC conversion module in can be a totem-pole rectification boost circuit. By controlling the on / off of four MOS transistors, the rectification and boost processes are completed using an inductor, and high-voltage DC is output through a capacitor. The second voltage adjustment module is a voltage regulation module that adjusts the rectified DC voltage to a target value (such as 48V). The second voltage adjustment module can be a DC / DC isolation buck converter. For better understanding of the second voltage adjustment module, as Figure 7 shown, Figure 7 is a schematic structural diagram of a second voltage adjustment module provided by an embodiment of the present application. Figure 7The second voltage adjustment module in it can be a DC / DC isolated buck circuit, which can be a resonant Inductor-Inductor-Capacitor (LLC) isolated buck circuit. The input side of this circuit has four active MOS transistors. By controlling their on / off states, the LLC resonant cavity composed of a transformer, an inductor, and a capacitor is charged and discharged for regulation. The voltage is stepped down using the turns ratio of the primary and secondary windings of the transformer. Finally, the regulated output of high-voltage DC is achieved through four passive diodes and a capacitor on the output side. This solution has high efficiency. At the same time, the presence of the transformer solves the problem of no isolation for AC voltage input and improves the safety of voltage conversion.

[0062] The second diode is a unidirectional conduction device (such as a fast recovery diode), which is used to prevent the current from flowing back to the AC path and at the same time realizes the priority control of multiple power paths. The second preset voltage is the output voltage value set according to the load demand (such as 48V ± 1%), which needs to meet the power consumption specifications of servers, storage devices, etc. The second anti-interference module is connected between the AC power system and the AC conversion module, and is mainly used for anti-interference processing of the input alternating current. By using components such as inductors, capacitors, and filters, high-frequency noise, electromagnetic interference and other signals in the alternating current are removed to ensure that the alternating current entering the AC conversion module is pure. The second anti-interference module can effectively improve the anti-interference ability of the power system and prevent the power transmission from being unstable due to external interference. The alternating current processed by the second anti-interference module enters the AC conversion module. The main function of the AC conversion module is to convert the alternating current into direct current. The AC conversion module generally uses a rectifying device (such as a bridge rectifier) to rectify the alternating current into direct current and smooth the current through filtering components to reduce current fluctuations. The converted direct current will be transmitted to the second voltage adjustment module. After receiving the direct current from the AC conversion module, the second voltage adjustment module adjusts the voltage to the standard voltage required by the load. The second voltage adjustment module precisely adjusts the DC voltage through a regulator (such as a DC-DC converter) to ensure that the output voltage meets the power demand of the load. After adjustment, the stable direct current will be output to the load through the second diode. The second diode is used at the output end of the direct current, and its function is to ensure that the current flows only in one direction, avoiding damage to the power system due to reverse current flow. The use of the diode is a safety measure in the power system to ensure the unidirectionality and safety of power transmission. Finally, the direct current passing through the second diode will be output to the load to supply power to it. Through the processing of the above modules, it is ensured that the power supply is stable, reliable, and accurate, thus meeting the power demand of the load equipment.

[0063] Through the combination of the second anti-interference module, AC conversion module, second voltage adjustment module, and second diode, alternating current can be efficiently and reliably converted into direct current, and the output voltage can be precisely adjusted to avoid the instability of power supply caused by voltage fluctuations and interference. This not only ensures the long-term stable operation of the load equipment but also improves the overall efficiency and reliability of the power system.

[0064] To facilitate a better understanding of the first power supply component, as Figure 8 shown, Figure 8 This is a schematic structural diagram of another first power supply component provided by an embodiment of the present application. Taking the adaptation of high-voltage DC input under the most common AC input as an example, in the B path, the AC input is (traditional three-phase AC 380V power grid or traditional single-phase AC 220V power grid). Due to problems such as voltage fluctuations and harmonic distortions in the power grid, the AC voltage first passes through the EMI and buffer circuits to eliminate some common-mode / differential-mode interference, and then passes through the PFC rectifier and boost circuit to convert 220V / 380V AC into 800V / 400V DC. Then, it is further reduced to 400V DC regulated voltage through the DC / DC isolation and buck module, and finally, diode 2 is used to prevent current backflow. For the high-voltage DC input in the A path (400V / 800V high-voltage DC input), it also first passes through the EMI and buffer circuits, and then passes through the DC / DC voltage regulation module to reduce the voltage to 400VDC. Different from the AC input, the pre-stage high-voltage DC usually comes with an isolation cabinet, so a non-isolation module is used here to further improve the efficiency. Finally, diode 1 is used to connect to the output bus. Due to the existence of diode 1 and 2, the higher-voltage path in the A path and B path is output, and the other path is used as a hot standby. Using high-voltage DC as the main path and AC voltage as the hot standby not only improves the power supply efficiency but also ensures a certain degree of redundancy.

[0065] In some embodiments, to facilitate a better understanding of the second power supply component, as Figure 9 shown, Figure 9 This is a schematic structural diagram of a second power supply component provided by an embodiment of the present application. The second power supply component includes: a third anti-interference module, a second DC conversion module, and a third DC conversion module; The third anti-interference module is electrically connected to the DC power supply, the second DC conversion module, and the third DC conversion module respectively, and the load is electrically connected to the second DC conversion module and the third DC conversion module respectively; The second power supply component switches the second DC conversion module or the third DC conversion module to supply power to the load according to the power quality of the DC power supply; wherein, the second DC conversion module and the third DC conversion module are used to convert DC power supplies with different power qualities into direct current; The third anti-interference module is used to perform anti-interference processing on the DC power supply and transmit the DC power supply after the anti-interference processing of the third anti-interference module to the second DC conversion module or the third DC conversion module; The third DC conversion module is further used for: when the power quality is greater than the preset threshold, the second power supply component switches to the third DC conversion module to supply power to the load; The third DC conversion module is used to convert the DC power supply after the anti-interference processing of the third anti-interference module into direct current and transmit the direct current to the load.

[0066] The second power supply component is used to switch between the two DC power supplies and the second and third DC conversion modules. By monitoring the power quality of the two DC power supplies in real time, it decides which power path is most suitable for connecting to the load. The second DC conversion module is used to receive the direct current from the second power supply component and transmit it to the load. The second DC conversion module supports efficient power transmission and ensures stable power supply. The third DC conversion module is similar to the second DC conversion module and is also used to receive the direct current from the second power supply component and transmit the power to the load. Its role is to serve as a backup path to ensure the redundancy and stability of power supply. Power quality refers to the comprehensive evaluation index of the electrical energy parameters of the DC power supply, including but not limited to voltage stability (fluctuation range), ripple factor (noise level), and load regulation rate (dynamic response ability). The preset threshold refers to the power quality threshold for determining whether the DC power supply is available (such as voltage fluctuation ≤ ±5%, ripple factor ≤ 3%, load regulation rate ≤ 2%). The connection target is the power supply path target selected according to the power quality judgment result.

[0067] When the power quality of one of the DC power supplies deteriorates, the second power supply component can quickly switch to the other DC power supply with qualified power quality to ensure continuous power supply to the load equipment. This redundant design enhances the reliability of the power supply system and reduces the risk of service interruption caused by single-point failures.

[0068] The role of the third anti-interference module is to filter out electromagnetic interference in the direct current, improve the power quality, and ensure that the subsequent circuits and data center equipment are not affected by interference. The third anti-interference module can be an EMI and buffer circuit. The switching switch plays a key role in the first circuit switching module. According to the power quality situation processed by the third anti-interference module, it switches between the two DC power supplies according to the preset rules, and transmits the DC power with qualified power quality to the corresponding connection target to ensure stable and reliable power supply for the data center.

[0069] The input terminals of the third anti-interference module are respectively connected to two DC power supplies, and low-resistance and high-precision wires are used to ensure the smooth inflow of DC power into the anti-interference module. The third anti-interference module is composed of filtering elements such as inductors and capacitors, which can effectively filter out high-frequency electromagnetic interference. Its output terminal is connected to the switching switch. The switching switch selects an electromagnetic relay or a semiconductor switch with fast response and high reliability, and the control circuit is designed to achieve precise switching according to the power quality monitoring signal. The power quality monitoring chip is connected after the third anti-interference module to collect key parameters of the DC power after anti-interference processing in real time, such as voltage, current, etc. The output terminal of the chip is connected to the micro-control component. The micro-control component processes and analyzes the collected data according to the preset power quality standard to judge whether the power quality meets the standard. The output terminal of the micro-control component is connected to the control terminal of the switching switch, and the switching switch action is precisely controlled by sending a control signal to achieve the circuit switching function.

[0070] The stable power supply reduces the additional stress on the data center equipment caused by power quality problems such as voltage fluctuations and ripple interference, thereby effectively extending the service life of the equipment, reducing the equipment maintenance and replacement costs, and improving the reliability and stability of the entire power supply system.

[0071] In some embodiments, please continue to refer to Figure 9 , the second DC conversion module includes: a third voltage adjustment module; The third voltage adjustment module is respectively connected to the third anti-interference module and the load; In the case where the power quality is less than or equal to the preset threshold, the second power supply component switches to the second DC conversion module to supply power to the load; The third voltage adjustment module is used to adjust the voltage of the DC power supply after anti-interference processing by the third anti-interference module to a preset voltage to obtain DC power, and transmit the DC power to the load.

[0072] The second DC conversion module is used to receive the DC power signal from the second power supply component, adjust its voltage, and finally send the adjusted DC power to the load. It is a key part of the system responsible for voltage adaptation and transmission, ensuring stable power and meeting the preset standards. The third voltage adjustment module is used to adjust the voltage of the transmitted DC power. It adjusts the voltage so that the current reaches the preset voltage level (the third preset voltage) to ensure that the power quality meets the requirements of the load. The third diode, as a one-way conduction element of the current, is responsible for sending the DC power processed by the third voltage adjustment module to the load. Its function is to prevent the current from flowing back and ensure that the current is stably output in the predetermined direction. The third preset voltage is a voltage standard preset according to the power demand of the load. The third voltage adjustment module adjusts the voltage of the DC power to a voltage that meets this standard.

[0073] The second DC conversion module receives direct current from the second power supply component and adjusts it to the required preset voltage through the third voltage adjustment module. First, appropriate direct current is sent to the second power supply component according to the power demand of the load. Inside the second power supply component, the direct current signal first passes through the third voltage adjustment module. The third voltage adjustment module is designed according to the load's requirements for power quality to ensure that the provided voltage is both stable and meets the predetermined third preset voltage. When the voltage is adjusted, the third voltage adjustment module transmits it to the third diode. The core of the third voltage adjustment module is to adjust the voltage of the input direct current through devices such as switch control, voltage stabilizing elements, and filters. It can stably output the required preset voltage according to the change of the input voltage. This voltage adjustment process ensures that the output direct current can meet the high requirements of the load for power quality. The adjusted direct current passes through the third diode and is output. The function of the third diode is to ensure the unidirectional flow of current and prevent the reverse flow of current, thereby ensuring the stability of the power supply. The current passing through this diode is smoothly delivered to the load to complete the power supply task.

[0074] It can achieve automatic voltage adjustment and current monitoring without manual intervention, reducing the occurrence of human errors and improving the system management efficiency at the same time. This automated intelligent management method makes the operation of the power system more efficient and accurate. Through this design, it can provide a stable and high-quality power supply, meet the power demands of different loads, and ensure the long-term stable operation of the equipment.

[0075] To facilitate a better understanding of the second power supply component, as Figure 10 shown, Figure 10 This is a schematic structural diagram of another second power supply component provided by the embodiment of the present application. The second power supply component: two-way high-voltage direct current (400V / 800V) input. First, the voltage input passes through the EMI and buffer circuits to filter out some voltage noise, and then passes through the switching switch to complete the switching of the two paths for the automatic transfer switch (ATS). Among them, path A is output by DC / DC non-isolated voltage stabilization in cooperation with diode 1, and path B is directly output through diode 2.

[0076] This topology saves space and cost by sharing EMI and buffer circuits on two paths. If the grid input quality is high, it can be switched to path B output through ATS to ensure the highest efficiency output. If the grid quality is poor, the voltage regulation solution of path A can be used to complete the high-voltage DC output. This architecture ensures that when the input voltage level is the same as the voltage level of the output bus, the use of diode direct pass eliminates the complex DC / DC or alternating current (AC) / DC conversion process, greatly improving the efficiency of power supply. At the same time, the retention of ATS and isolated voltage regulation solutions also provides a compatible solution for poor grid quality or inconsistent voltage levels.

[0077] In some embodiments, in order to facilitate a better understanding of the first power supply component, such as Figure 11 As shown, Figure 11 A schematic diagram of the structure of another first power supply component provided in an embodiment of the present application, wherein the first power supply component comprises: a first DC conversion module, an AC conversion module, and an energy storage component; A first DC conversion module, used to convert the DC power supply into DC power and transmit the DC power to the load; and an AC conversion module, used to convert the AC power supply into DC power and transmit the DC power to the load; The energy storage component is electrically connected to the energy storage power supply and the load respectively; The energy storage component is used to transmit stored energy to the load for power supply; The first DC conversion module is used to switch the first anti-interference module, the first voltage adjustment module, or the DC transmission module in the first DC conversion module to supply power to the load according to the power quality; Wherein, when the power quality is greater than a preset threshold, the first DC conversion module switches to the DC transmission module to supply power to the load; When the power quality is less than or equal to a preset threshold, the first DC conversion module switches to the first anti-interference module and the first voltage adjustment module to supply power to the load.

[0078] The first DC conversion module is responsible for extracting DC power from the DC power supply and transmitting it to the DC input terminal of the load. Its core function is to ensure the stable output of DC power and ensure that the power meets the needs of the load through voltage adjustment. The AC conversion module is responsible for extracting AC power from the AC power supply and transmitting it to the AC input terminal of the load. It supports conversion between different power systems to ensure stable AC power supply. The energy storage component is used to transmit the energy storage power supply to the load. Its main function is to keep the load running normally through the energy storage power supply when the main power supply is off or the power is interrupted.

[0079] The first DC conversion module is connected to the DC power supply through a wire with low resistance and high precision. The module internally includes key components such as a DC reactance interference module and a DC voltage stabilization circuit. The anti-interference module uses a filter network composed of inductors, capacitors and other components to filter out high-frequency electromagnetic interference in the DC power; the voltage stabilization circuit uses a high-precision linear voltage stabilization chip or a switching voltage stabilization chip, combined with peripheral resistors, capacitors and other components, to stabilize the input DC voltage within the voltage range required by the load DC device. The AC conversion module is connected to the AC power supply, and its internal structure includes an AC reactance interference module, an AC voltage stabilization circuit, etc. The anti-interference module uses technologies such as electromagnetic shielding and filter capacitors to resist external electromagnetic interference, and the voltage stabilization circuit uses an automatic voltage regulation device to stabilize the fluctuating AC voltage within the rated range, and the output end is connected to the AC device power supply interface of the load through the AC power supply line. The energy storage component is connected to the energy storage power supply and is composed of an anti-interference module, a voltage stabilization circuit, etc. The anti-interference module uses appropriate filter elements to prevent interference during the transmission of the energy storage power supply; the voltage stabilization circuit uses a voltage stabilization chip suitable for the characteristics of battery power supply to ensure stable output voltage, and is connected to the load through the energy storage power supply transmission line to supply power to the load in case of emergency.

[0080] By integrating three power transmission methods of DC power supply, AC power supply and energy storage power supply, the first power supply component can provide different types of power support according to the needs of the load. This diversity effectively avoids the risks of power shortage or unstable power quality that may occur with a single power source.

[0081] In some embodiments, please continue to refer to Figure 11 , the energy storage component includes: a fourth DC conversion module; The fourth DC conversion module is respectively connected to the energy storage power supply and the load; The fourth DC conversion module is used to convert the energy storage power supply into DC power and transmit the DC power to the load; Among them, the fourth DC conversion module includes: a fourth voltage adjustment module; The fourth voltage adjustment module is respectively connected to the energy storage power supply and the load; The fourth voltage adjustment module is used to adjust the voltage of the energy storage power supply to a preset voltage to obtain DC power and transmit the DC power to the load.

[0082] The fourth DC conversion module is a key subsystem in the first power supply component, specifically responsible for managing the power output of the energy storage power supply. It ensures that in emergency situations such as power outages or main power failures, the energy storage power supply can safely and stably provide power support for load devices, guaranteeing the uninterrupted operation of the business. The fourth voltage adjustment module is the core component in the fourth DC conversion module. Its main function is to adjust the DC voltage of the energy storage power supply to ensure that the output voltage is stable at the preset voltage value required by the load device. It provides precise power support for the device through high-precision voltage conversion technology. The circuit breaker plays a key role in circuit protection and control in the fourth DC conversion module. It can achieve on-off control of the circuit under normal conditions to ensure the normal output of current; in case of faults such as overload or short circuit, it can quickly cut off the circuit to protect the battery backup unit and the entire power supply system from damage.

[0083] The fourth voltage adjustment module is connected to the battery backup unit through low-resistance and high-precision wires to ensure the smooth flow of battery power into the adjustment circuit. The fourth voltage adjustment module uses a DC-DC converter with a wide input voltage range, which can handle fluctuations in battery voltage and ensure a stable output of the preset voltage even when the power of the energy storage power supply changes. Appropriate inductors, capacitors and other components are equipped on its periphery for filtering and stabilizing the voltage. The output end of the fourth voltage adjustment module is connected to the input end of the circuit breaker. The circuit breaker selects a miniature circuit breaker with high breaking capacity and fast response, which can withstand the maximum output current of the battery backup unit and quickly cut off the circuit in case of overload or short circuit faults. The output end of the circuit breaker is connected to the power supply interface of the load device to ensure the normal output of current.

[0084] To facilitate a better understanding of the fourth DC conversion module, as Figure 12 shown, Figure 12 FIG. is a schematic structural diagram of a fourth DC conversion module provided by an embodiment of the present application, Figure 12 in which the fourth DC conversion module can be a bidirectional DC / DC module. The bidirectional DC / DC module enables the energy storage power supply to both draw power from the bus to charge the battery and boost the voltage to output high-voltage DC to the bus, playing the role of supplying power to the load and stabilizing the output bus voltage. The buck-boost circuit topology of the bidirectional DC / DC is different from the LLC topology. The two sides of the bidirectional topology are symmetrical, both consisting of four active MOS transistors plus an LLC resonant cavity composed of a transformer, an inductor and a capacitor. Through different control methods, the voltage can be boosted and bucked simultaneously, and the power can also flow bidirectionally.

[0085] In case of a power outage or main power failure, the energy storage power supply transmission module can quickly access and provide stable power support for load devices, guaranteeing the uninterrupted operation of the business and reducing the risks of data loss and service interruption caused by power outages.

[0086] To facilitate a better understanding of the first power supply component, as Figure 13 shown, Figure 13 FIG. is a schematic structural diagram of another embodiment provided by the present application. The first power supply component: The A path has a high-voltage DC (400V / 800V) input, the B path has an AC input (a traditional three-phase AC 380V power grid or a traditional single-phase AC 220V power grid), and the battery pack inside the whole cabinet is used for power backup (48V / 400V) as the C path. First, the B path AC input is the same as in the first case. The high-voltage DC input of the A path is divided into the A1 path and the A2 path by the transfer switch ATS. Similar to the second case, the A2 path is used as the direct-through solution when the power grid and the pre-stage voltage regulation are in good condition, and the A1 path is used as the backup isolation voltage regulation solution.

[0087] Among them: The A1 path, the A2 path, and the B path use three diodes to prevent current backflow, and at the same time, the highest voltage among the three paths is taken as the output, and the rest are used as backup voltages. The battery backup module inside the whole cabinet is used as the C path, and the bidirectional DC / DC is used to be mounted on the output bus through the disconnection switch. For this AC / DC input power supply architecture, since the high-voltage DC has the highest efficiency, it is recommended to use the high-voltage DC input of the A path as the main path and the AC input of the B path as the hot backup power. Since the load pre-stage usually uses a Panama power supply or an HVDC module for voltage conversion, the input high-voltage DC has been somewhat voltage-regulated and the AC / DC voltage isolation has been completed. Therefore, the A2 path diode 2 direct-through method can be adopted, thus ensuring the highest efficiency. At this time, the C path battery pack backup is connected, and the high-voltage DC is further voltage-regulated through the bidirectional DC / DC. That is, the A2 path and the C path are preferably used as the always-on paths. If the power grid quality is poor and the battery pack cannot complete voltage regulation, then it is switched to the A1 path, and the AC input of the B path has a lower efficiency as the backup power.

[0088] A load power supply architecture adapted to any AC / DC input, including the power supply adaptation of one AC and one DC input, two DC inputs, and one DC and one AC plus an energy storage system. It can not only achieve the high-efficiency direct-through of high-voltage DC under high power quality power supply, but also achieve the voltage regulation conversion under low-quality power supply. By using the battery backup unit (BBU) module inside the whole cabinet, the power quality of the high-voltage DC is improved at the whole cabinet level through the bidirectional DC / DC.

[0089] According to the embodiments of the present application, the present application also proposes a power supply method, as Figure 14 shown, Figure 14 FIG. is a schematic flowchart of a power supply method provided by an embodiment of the present application. The method is applied to a power supply system, and the method includes the following steps: Step 101, obtain the power supply requirements of the load.

The control component switches the first power supply component and / or the second power supply component to supply power to the load according to the power supply requirements of the load, so that the first power supply component and the second power supply component adapt to different power supply requirements of the load, improving the compatibility of the power supply components. Therefore, the technical problem of poor compatibility of the power supply components can be solved, and the technical effect of improving the compatibility of the power supply components can be achieved.
