[0037] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] It should be noted that, in the description of this application, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. The terms "first," "second," etc., in this application are used to distinguish similar objects, and are not used to describe a particular order or sequence.

[0039] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] In conjunction 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 is described herein.

[0041] An embodiment of the present application provides a power supply system, and the power supply system is described in detail in conjunction with the execution process of the power supply system.

[0042] Figure 1 A schematic diagram of a power supply system according to an embodiment of the present invention is shown in FIG. Figure 1 As 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;

[0043] A control component refers to a central control unit with integrated logic processing capabilities (such as a programmable logic controller (PLC), a microcontroller component, or a dedicated integrated circuit), which has data acquisition, logic judgment, and command sending functions, and is used to coordinate the start, stop, and switching of multiple power components. The power supply demand of the load is the specific power supply method required by the load, covering different types and combinations such as AC power supply, DC power supply, and energy storage power supply, depending on the operating requirements of the load and its overall power supply components. The power supply component is a power supply structure that usually includes power distribution, redundancy settings, switching mechanisms, etc. The power supply component includes but is not limited to the power supply architecture.

[0044] 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.

[0045] The load's power supply requirement refers to the type of power input it currently needs to match. Specifically, it includes: one AC power supply and one DC power supply, for example, a combination of a 380V AC mains power supply and a 240V DC power supply; two DC power supplies, for example, two independent 240V DC power supplies (such as a photovoltaic DC power supply and a battery DC power supply). The load's power supply components are specific power supply components matched according to the mapping relationship. For example, the first power supply component is a power supply unit that supports both DC and AC input modes, outputs stable DC power through an internal conversion module, and is compatible with mixed AC and DC transmission modules; the second power supply component is a dual-path conversion unit specifically designed to handle DC inputs of varying power quality, selecting the optimal conversion path based on the input DC power quality (such as voltage fluctuation and ripple factor). The power supply requirement is at least one of the first power supply requirement of one AC power supply and one DC power supply, or the second power supply requirement of two DC power supplies.

[0046] Based on the power supply demand of the load and the pre-established mapping relationship between the power supply demand and the power supply component, the control component determines the power supply component corresponding to the power supply demand of the load, and sends a start instruction to the power supply component of the load so that the power supply component of the load can supply power to the load.

[0047] Pre-established mappings between power requirements and power components are established before the power supply system is put into operation. Based on the load's power supply planning and design, and through extensive experimentation and data analysis, technicians establish precise correspondences between various power requirements and the power components that best meet them. These mappings are stored in the control component's memory unit as a data table or structured configuration file, providing a basis for rapid decision-making.

[0048] The control component maintains a real-time communication connection with the load, and obtains its current power supply requirements through the signals sent by the load, including key parameters such as the required voltage, current, frequency, and power supply type, thereby clarifying the power supply requirements of the load. When the control component determines the power supply requirements 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 based on the query condition of the load's power supply requirements. For example, if the load's power supply requirements are one AC power supply and one DC power supply, the control component will find a pre-set power supply component in the mapping table that can provide both types of power at the same time. After determining the power supply component of the load, the control component generates a startup instruction containing the power supply component of the load and sends it to the power supply component via a dedicated communication line. After the power supply component receives the startup instruction, its internal control circuit immediately triggers the corresponding power conversion and transmission device, and begins to supply stable power to the load according to the startup instruction requirements to ensure the normal operation of the load.

[0049] The control unit can flexibly select a variety of power supply components based on the different power supply requirements of the load. Whether it is based on AC or DC power supply, the control unit can provide corresponding support to adapt to various application scenarios.

[0050] The first power supply assembly includes: a first DC conversion module for converting DC power supply into DC power and transmitting the DC power to the load; and an AC conversion module for converting AC power supply into DC power and transmitting the DC power to the load.

[0051] The first power supply component refers to a composite power supply system designed for simultaneous access to AC and DC power, including the following core modules: the first DC conversion module: a link for processing DC input signals, including filtering, voltage adjustment and isolation circuits; the AC conversion module: a link for processing AC input signals, including rectification, filtering and voltage conversion circuits.

[0052] The primary power supply requirement of one AC power source and one DC power source refers to the hybrid power supply mode required by the corresponding load. This requires the simultaneous or selective use of one AC power source (such as a 380V / 50Hz mains power) and one DC power source (such as a 240V DC backup power source). AC power refers to AC power drawn from an external grid or AC generator, typically requiring rectification and conversion to DC before supplying to the load. DC power refers to direct input DC power (such as from a solar array, battery bank, or high-voltage DC distribution system), which can be used with DC loads such as servers without rectification.

[0053] The hardware components of the first power supply assembly may include a first DC conversion module and an AC conversion module. The first DC conversion module may include, but is not limited to, an input interface for connecting the positive and negative terminals of a DC power source; an anti-interference module: an inductor and capacitor (LC) filter that suppresses high-frequency noise; a voltage adjustment module: an adjustable step-down circuit that stabilizes the input DC voltage to 48V (with a tolerance of ±2% fluctuation); and an isolation diode: to prevent current from flowing back into the DC source. The AC conversion module may include, but is not limited to, an input interface for connecting the live, neutral, and ground wires of an AC power source (such as a three-phase outlet); an AC conversion module: a full-bridge rectifier circuit that converts AC power into pulsating DC; an anti-interference module; and a filter circuit: an electrolytic capacitor that smooths the pulsating waveform. The voltage adjustment module: an isolated step-down converter that outputs a stable DC voltage; and an isolation diode: connected in parallel with the DC path to ensure that the DC power source is prioritized when dual inputs are present. However, it should be clarified that this statement does not limit the first power supply assembly to the aforementioned components; other components may also be used to form the first power supply assembly.

[0054] The power supply logic and control flow of the first power supply assembly can be either AC / DC parallel power supply or single power supply. 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 reverse-biased and closed, giving priority to DC power. If the DC input is abnormal (such as the voltage drops below 44V), the diode of the AC conversion module automatically conducts, switching to AC power. For single power supply, when only AC or DC is connected, the diode of the corresponding module conducts, directly powering the load.

[0055] To facilitate understanding, here's an example: When the mains power is normal and the backup DC power supply is online, the first DC converter module steps down the 240V input to 48V, which is then output to the load via a diode. The AC converter module is in hot standby mode (the rectifier module continues to operate, but the diode is cut off). If the mains power is interrupted, the first DC converter module detects the AC input failure (via a voltage sensor) and immediately increases its output power to full load, ensuring seamless failover.

[0056] 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-mentioned process, and can also be other processes.

[0057] By designing separate power modules for AC and DC power, and employing appropriate wiring and parameter configuration, the primary power supply component ensures stable AC and DC power to the load even in the event of external power supply fluctuations or partial equipment failure. For example, if the external AC power supply voltage drops, the AC conversion module can adjust the voltage while the primary DC conversion module continues to provide stable DC power, ensuring that devices that rely on DC power are not affected. This enhances load power reliability and reduces the risk of service interruption caused by power supply issues.

[0058] 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; wherein the second DC conversion module and the third DC conversion module are used to convert DC power supplies of different power qualities into DC power.

[0059] The secondary power supply assembly is a power supply system designed specifically to provide two DC power supplies. It contains multiple power conversion and transmission modules that receive external DC power and distribute and convert it into two DC power supplies that meet the load's requirements. It is a key component in implementing dual DC power supply. The secondary power supply requirement for a dual DC power supply refers to one of the power supply methods required by the load, including two DC power supplies. For example, some servers (i.e., loads) in certain data centers require two independent DC power supplies to improve power supply reliability and redundancy. If one DC power supply fails, the other can continue to power the equipment, ensuring uninterrupted operation of the data center.

[0060] The hardware components of the second power supply assembly may include a first circuit switching module, a second DC conversion module, and a third DC conversion module. The first circuit switching module may include, but is not limited to, an input interface: two DC input terminals with reverse polarity protection; a power quality detection circuit: a voltage sensor that collects voltage, current, and ripple data from the two inputs in real time; a switch: a dual-channel Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) array whose conduction state is controlled by a microcontroller. The second DC conversion module (main circuit) may 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 a set output voltage (e.g., 48V); an isolation diode to prevent current backflow from the backup circuit; and a third DC conversion module (backup circuit) may include a boost circuit: a boost converter to increase the backup DC input to a set voltage (e.g., 48V); and priority control logic: based on the first circuit switching module, determining whether the main circuit voltage is below a preset threshold (e.g., 44V). 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 the above-mentioned components. The first power supply component and the second power supply component can also be composed of other components.

[0061] The power supply logic and control flow of the second power supply assembly can provide either primary DC power supply or primary DC fault switching. For primary DC power supply, the first circuit switching module detects a primary DC voltage ≥45V and a ripple ≤3%, controls the MOSFET to conduct the primary circuit, and the second DC conversion module outputs 48V to the load. The third DC conversion module is in hot backup mode (the boost circuit is in standby mode and the diode is cut off). For primary DC fault switching, if the main DC voltage drops below 44V (e.g., insufficient photovoltaic output on a cloudy day), the switching module immediately disconnects the primary MOSFET and connects the backup MOSFET. The third DC conversion module activates the boost circuit, boosting the 192V battery input to 48V, which is then output through the diode.

[0062] To facilitate understanding, an example is provided. When the main DC power supply is stable, the PV array outputs 240V DC, which is stepped down to 48V by the secondary DC converter module and directly powers the server cabinet. The backup battery remains in a floating charge state. In the event of a sudden loss of main DC power, the PV input is interrupted due to a fault. The switching module switches to the third DC converter module within 5ms. The boost circuit ensures stable output voltage, and the data center load seamlessly switches.

[0063] 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-mentioned process, and can also be other processes.

[0064] By providing two DC power supplies, power supply redundancy is enhanced. If one DC power supply fails, the other 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.

[0065] In practical applications, the load may be powered by energy storage. When this is the case, improvements to the first power supply assembly are necessary. The hardware components of the first power supply assembly may include a DC conversion module, an AC conversion module, and an energy storage component. The DC conversion module may include, but is not limited to, a DC transmission module: it processes high-quality DC input (e.g., 240V ± 5%) and directly steps down the voltage to a set output voltage (e.g., 48V). An anti-interference module and a voltage regulation module: they process low-quality DC input (e.g., voltage fluctuations of ±20%) and stabilize the output through a buck-boost converter circuit. The AC conversion module may include, but is not limited to, a rectifier and filter circuit: it converts AC power to smooth DC power; and an isolated DC-DC converter (DC / DC) converter: it steps down 300V DC to 48V DC. The battery power transmission module may include, but is not limited to, a bidirectional DC / DC circuit: it charges the battery (constant voltage / constant current mode) during normal operation and boosts the output voltage (e.g., 192V battery → 48V output) during power outages. A circuit breaker: a MOSFET array controls the battery's on / off state 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-mentioned components. The first power supply component can also be composed of other components.

[0066] To facilitate understanding, an example is provided. Scenario 1: The AC power and DC power supply are normal. The AC power supply is rectified and converted to a 48V output, and the DC power supply is in hot backup mode (the second circuit switching module keeps the DC input path closed but the diode is cut off). Scenario 2: The AC power is interrupted and the DC power supply is abnormal. The control component detects an AC failure and a DC input voltage less than 200V. It immediately closes the MOSFET in the energy storage power supply path, boosting the voltage to 48V and sending an alarm signal.

[0067] 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-mentioned process, and can also be other processes.

[0068] By integrating the two power components, loads can receive a stable power supply despite varying power demands and power failure scenarios. Even if one power source fails, the energy storage or other power source ensures continued load operation, preventing load downtime or data loss due to power outages.

[0069] Through the present application, the control component switches the first power component and / or the second power component to supply power to the load according to the power supply demand of the load; the first power component includes: a first DC conversion module for converting DC power supply into DC power and transmitting DC power to the load; and an AC conversion module for converting AC power supply into DC power and transmitting DC power to the load; the second power component includes: a second DC conversion module and a third DC conversion module. The second power 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 of different power qualities into DC power. The control component switches the first power component and / or the second power component to supply power to the load according to the power supply demand of the load, so that the first power component and the second power component can adapt to the different power supply demands of the load, thereby improving the compatibility of the power components. Therefore, the technical problem of poor compatibility of the power components can be solved, and the technical effect of improving the compatibility of the power components can be achieved.

[0070] In some embodiments, in order to facilitate a better understanding of the first power supply component, such as Figure 2 As shown, Figure 2 A schematic structural diagram of a first power supply assembly provided in an embodiment of the present application, wherein the first power supply assembly includes: a first DC conversion module and an AC conversion module;

[0071] 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 electrically connected to the load respectively;

[0072] The first DC conversion module transmits DC power in the DC power supply to the load;

[0073] The AC conversion module transmits AC power from the AC power supply to the load.

[0074] The first DC conversion module is a power transmission device used to transfer DC power to the load. This module is responsible for extracting 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 is a power transmission device used to transfer AC power to the load. This module is responsible for extracting power from the AC power supply and delivering it to the load, ensuring the stability and reliability of the AC power.

[0075] When configuring the primary power supply components for a load, the load's power requirements and redundancy requirements are the primary considerations. The architecture primarily includes: The primary DC conversion module: This module transmits power from a DC power source (such as a battery pack or DC power system) to the load via a DC transmission module. This module is electrically connected to the DC power supply and uses a specialized power converter (such as a DC converter) to regulate the voltage and ensure stable power supply. The AC conversion module: This module transmits AC power to the load via the AC power supply. This module is electrically connected to the AC power supply, ensuring stable and adjustable power to meet the load's power requirements. The AC power is then stepped down or stepped up to the appropriate voltage level by a transformer before being supplied to the load.

[0076] The DC power source transmits power to the load via the first DC conversion module. First, the DC power source generates power for the DC power supply via a battery or rectifier. The first DC conversion module then transmits the stable DC power to the power distribution unit within the load. The AC power source transmits power to the load via the AC conversion module. Through the AC power transmission system, AC power enters the load from the grid and is then supplied to the load through voltage regulation equipment (such as a transformer) to provide power suitable for the load's needs.

[0077] The first power supply assembly enables redundant switching between DC and AC power. If the AC power fails, the system automatically switches to the DC power module to provide power. Conversely, if the DC power fails, the AC power module can replace it and continue providing power. Through the power management system, the system can flexibly adjust the power source based on load conditions to ensure uninterrupted load operation. The power management system monitors each module in the first power supply assembly in real time. The system dynamically adjusts the power supply method and power distribution based on the real-time load requirements. For example, under light load conditions, the system may prioritize DC power to avoid energy waste; under heavy load conditions, the system may prioritize AC power to provide more power support.

[0078] By configuring the first DC conversion module and the AC conversion module, the load can still receive a stable power supply in the event of a power failure. Whether the DC or AC power fails, the backup power supply will automatically start to ensure continuous and stable operation of the load.

[0079] In some embodiments, please refer to Figure 2 , the first DC conversion module includes: a first anti-interference module and a first voltage adjustment module;

[0080] 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;

[0081] 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 by the first anti-interference module to the first voltage adjustment module;

[0082] The first voltage adjustment module is used to adjust the voltage of the DC power supply after the anti-interference processing by the first anti-interference module to a preset voltage, obtain DC power, and transmit the DC power to the load.

[0083] The first anti-interference module is a filter module used to suppress high-frequency noise, surge and electromagnetic interference in DC input, which is usually composed of, but not limited to, inductors, capacitors and transient voltage suppressors. In order to better understand the anti-interference module, Figure 3 As shown, Figure 3 This is a structural schematic diagram of an anti-interference module provided in 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 magnetic circuit offset in the common-mode inductor.

[0084] The first voltage adjustment module is a voltage regulator module that adjusts the input DC voltage to the target value (such as 48V) and supports buck (Buck), boost (Boost) or buck-boost (Buck-Boost) topology. In order to better understand the voltage adjustment module, Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of a voltage adjustment module provided in an embodiment of the present application. The voltage adjustment module can be a non-isolated voltage stabilizing circuit for a DC / DC circuit. The non-isolated voltage stabilizing circuit for a DC / DC circuit can be Figure 4 The Buck step-down circuit in the Buck step-down circuit is used to step down the voltage. The Buck step-down circuit may contain two Metal Oxide Semiconductor (MOS) tubes, an inductor, and a capacitor. By controlling the on-off of the MOS tube and thus the charging or freewheeling time of the inductor, non-isolated step-down is achieved over a wide voltage range.

[0085] The first diode can be a unidirectional conducting device (such as a Schottky diode) to prevent reverse current flow to the DC source and enable priority control of multiple power paths. The preset voltage can be an output voltage value set based on load requirements (e.g., 48 ± 1%), which must be compatible with the power specifications of servers, network equipment, and other equipment.

[0086] The first anti-interference module is located between the DC power supply and the first voltage regulation module. Its primary function is to perform anti-interference processing on the incoming DC power, removing electromagnetic interference and noise that could affect power stability. The first anti-interference module typically consists of anti-interference components such as inductors and capacitors, ensuring current purity through filtering and suppression. The first voltage regulation module regulates the DC power from the first anti-interference module. It operates by using a voltage regulator (such as a DC / DC converter) to ensure that the voltage meets the load requirements. The first voltage regulation module can be a non-isolated DC / DC converter. The first diode is installed at the output of the first voltage regulation module. Its primary function is to ensure that current flows in only one direction, thereby preventing reverse current flow and damaging the power system.

[0087] When the DC power supply transmits power through the first DC transmission module, the DC current first enters the first anti-interference module, which performs noise suppression and interference filtering on the input current to ensure that the power signal is not affected by external factors. The current after interference suppression is transmitted through the first anti-interference module to the first voltage adjustment module. The first voltage adjustment module adjusts the DC voltage after anti-interference processing. Based on the power demand of the load, the first voltage adjustment module adjusts the voltage to a preset standard value. The adjusted voltage is transmitted to the first diode. The first diode outputs the adjusted DC voltage to the load, ensuring that the current flows in only one direction, thereby preventing reverse current flow from damaging the power system. Through the above processing, the DC voltage is adjusted and safely transmitted to the load's power supply system through the diode. The entire process ensures stability, reliability, and safety during power transmission.

[0088] Through redundant design, precise voltage regulation and anti-interference measures, the load failure rate caused by power fluctuations or interference can be effectively reduced, thereby reducing maintenance workload and costs and increasing load service life.

[0089] In some embodiments, please refer to Figure 2 , the AC conversion module includes: a second anti-interference module, an AC conversion module, and a second voltage adjustment module;

[0090] 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 adjustment module;

[0091] The second anti-interference module is used to perform anti-interference processing on the AC power supply and transmit the AC power supply after the anti-interference processing by the second anti-interference module to the AC conversion module;

[0092] The AC conversion module is used to convert the AC power supply after the anti-interference processing by the second anti-interference module into a second DC power, and transmit the second DC power to the second voltage adjustment module;

[0093] 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.

[0094] The AC conversion module is the AC power input processing link, consisting of anti-interference, rectification, voltage regulation, and isolation circuits, used to convert AC power into stable DC power suitable for the load. The second anti-interference module is a filtering circuit used to suppress high-frequency noise, surges, and electromagnetic interference (EMI) in the AC input. It typically consists of common-mode inductors, capacitors, and gas discharge tubes.

[0095] The AC conversion module is a rectifier module (such as a full-bridge rectifier 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) rectifier boost circuit. In order to better understand the AC conversion module, Figure 5 As shown, Figure 5 This is a structural diagram of an AC conversion module provided in an embodiment of the present application. Taking single-phase 220V AC input as an example, the AC conversion module is a PFC rectifier boost circuit. Figure 5 The Boost type rectifier boost circuit in the circuit first uses a rectifier bridge and a large capacitor to convert the input AC voltage into DC, and then further boosts the voltage to 400V / 800V DC voltage through the Boost circuit. In addition, you can also use Figure 6 The AC conversion module shown, Figure 6 This is a structural diagram of another AC conversion module provided in an embodiment of the present application. Figure 6 The AC conversion module in the circuit can be a totem pole rectifier and boost circuit. By controlling the on and off of four MOS tubes, the inductor is used to complete the rectification and boost process, and the high-voltage DC is output through the capacitor. The second voltage adjustment module is a voltage regulator module that adjusts the rectified DC voltage to the target value (such as 48V). The second voltage adjustment module can be a DC / DC isolated step-down converter. In order to facilitate a better understanding of the second voltage adjustment module, as shown in the figure below: Figure 7 As shown, Figure 7 This is a structural diagram of a second voltage adjustment module provided in an embodiment of the present application. Figure 7The second voltage regulation module in the circuit is a DC / DC isolated step-down circuit, which can be a resonant inductor-inductor-capacitor (LLC) isolated step-down circuit. Four active MOS transistors are used on the input side of this circuit to regulate the charge and discharge of the LLC resonant cavity composed of a transformer, inductor, and capacitor by controlling their on / off state. The voltage is stepped down using the transformer's primary-to-secondary turns ratio. Finally, four passive diodes and capacitors on the output side achieve a regulated high-voltage DC output. This solution offers high efficiency, and the presence of a transformer eliminates the issue of unisolated AC voltage input, improving the safety of voltage conversion.

[0096] The second diode is a unidirectional conducting device (such as a fast recovery diode) that prevents reverse current flow into the AC path and enables priority control of multiple power paths. The second preset voltage is an output voltage value set based on load requirements (e.g., 48V ± 1%) and must meet the power requirements of servers, storage devices, and other devices. The second anti-interference module is connected between the AC power system and the AC conversion module and is primarily responsible for anti-interference processing of the incoming AC power. By using components such as inductors, capacitors, and filters, it removes high-frequency noise, electromagnetic interference, and other signals from the AC power, ensuring that the AC power is pure when it enters the AC conversion module. The second anti-interference module effectively improves the power system's anti-interference capabilities and prevents unstable power transmission caused by external interference. After processing by the second anti-interference module, the AC current enters the AC conversion module, whose main function is to convert the AC power into DC power. The AC conversion module typically uses a rectifier (such as a bridge rectifier) ​​to convert the AC power into DC power and uses filtering components to smooth the current and reduce current fluctuations. The converted DC power is then transmitted to the second voltage adjustment module. After receiving the DC power 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 regulates the DC voltage using a regulator (such as a DC-DC converter) to ensure that the output voltage meets the load's power requirements. After adjustment, the stable DC power is output to the load through a second diode. The second diode, used at the DC output, ensures that current flows in only one direction, preventing damage to the power system caused by reverse current flow. The use of diodes is a safety measure in the power system, ensuring unidirectional and safe power transmission. Ultimately, the DC current passing through the second diode is output to the load, powering it. Through the processing of these modules, a stable, reliable, and accurate power supply is ensured, thus meeting the power requirements of the load.

[0097] The combination of the second anti-interference module, AC conversion module, second voltage adjustment module, and second diode efficiently and reliably converts AC power into DC power and precisely regulates the output voltage, avoiding unstable power supply caused by voltage fluctuations and interference. This not only ensures the long-term stable operation of load equipment, but also improves the overall efficiency and reliability of the power system.

[0098] In order to better understand the first power supply component, Figure 8 As shown, Figure 8 This is a structural diagram of another first power supply component provided in an embodiment of the present application. The first power supply component: taking the most common AC input with high-voltage DC input as an example, where line B is an AC input (a traditional three-phase AC 380V grid or a traditional single-phase AC 220V grid). Due to voltage fluctuations and harmonic distortion in the grid, the AC voltage first passes through the EMI and buffer circuits to eliminate some common-mode / differential-mode interference, and then undergoes PFC rectification and boosting to convert the 220V / 380V AC into 800V / 400V DC. The voltage is then reduced to 400V DC for stabilization through a DC / DC isolation step-down module, and finally diode 2 is used to prevent current backflow. For line A high-voltage DC input (400V / 800V high-voltage DC input), it first passes through the EMI and buffer circuits, and then passes through the DC / DC voltage regulator module to reduce the voltage to 400VDC. Unlike the AC input, the front-stage high-voltage DC usually has an isolation cabinet, so a non-isolated module is used here to further improve efficiency. Finally, diode 1 is used to connect to the output bus. Thanks to diodes 1 and 2, the higher voltage of paths A and B is output, while the other path serves as a hot standby. Using high-voltage DC as the primary path and AC voltage as a hot standby not only improves power supply efficiency but also ensures a certain degree of redundancy.

[0099] In some embodiments, in order to facilitate a better understanding of the second power supply component, as shown in FIG. Figure 9 As shown, Figure 9 A schematic structural diagram of a second power supply assembly provided in an embodiment of the present application, wherein the second power supply assembly includes: a third anti-interference module, a second DC conversion module, and a third DC conversion module;

[0100] 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;

[0101] 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 of different power qualities into DC power;

[0102] 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 by the third anti-interference module to the second DC conversion module or the third DC conversion module;

[0103] The third DC conversion module is further configured to: when the power quality is greater than a preset threshold, the second power supply component switches to the third DC conversion module to supply power to the load;

[0104] The third DC conversion module is used to convert the DC power supply after the anti-interference processing by the third anti-interference module into DC power, and transmit the DC power to the load.

[0105] The second power supply assembly switches between the two DC power supply paths and the second and third DC conversion modules. By monitoring the power quality of the two DC power supply paths in real time, it determines which power path is most suitable for connecting the load. The second DC conversion module receives DC power from the second power supply assembly and transmits it to the load. The second DC conversion module supports efficient power transmission, ensuring a stable power supply. Similar to the second DC conversion module, the third DC conversion module receives DC power from the second power supply assembly and transmits it to the load. It serves as a backup path, ensuring redundancy and stability of the power supply. Power quality refers to a comprehensive evaluation of DC power supply parameters, including but not limited to voltage stability (fluctuation range), ripple factor (noise level), and load regulation (dynamic response capability). Preset thresholds are power quality thresholds used to determine whether the DC power supply is available (e.g., voltage fluctuation ≤ ±5%, ripple factor ≤ 3%, load regulation ≤ 2%). The connection target is the power supply path selected based on the power quality assessment results.

[0106] If the power quality of one DC power supply line deteriorates, the secondary power supply component can quickly switch to another 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 failure.

[0107] The third anti-interference module filters out electromagnetic interference (EMI) from the DC power, improving power quality and protecting subsequent circuits and data center equipment from interference. This module can serve as an EMI and buffer circuit. The switch plays a key role in the first circuit switching module. Based on the power quality determined by the third anti-interference module, it switches between the two DC power supplies according to preset rules, transmitting qualified DC power to the corresponding connected destination, ensuring stable and reliable power supply in the data center.

[0108] The input end of the third anti-interference module is connected to two DC power supplies respectively, and low-resistance, high-precision wires are used to ensure that DC power flows smoothly into the anti-interference module. The third anti-interference module is composed of filtering components such as inductors and capacitors, which can effectively filter out high-frequency electromagnetic interference. Its output end is connected to the switching switch, which uses electromagnetic relays or semiconductor switches with fast response and high reliability. The control circuit is designed to achieve precise switching based on the power quality monitoring signal. The power quality monitoring chip is connected after the third anti-interference module and collects key DC parameters such as voltage and current after anti-interference processing in real time. The output end of the chip is connected to the microcontroller component, which processes and analyzes the collected data according to the preset power quality standards to determine whether the power quality meets the standards. The output end of the microcontroller component is connected to the switching switch control end, which accurately controls the switching switch action by sending control signals to realize the circuit switching function.

[0109] Stable power supply reduces the additional stress on data center equipment caused by power quality issues such as voltage fluctuations and ripple interference, thereby effectively extending the service life of the equipment, reducing equipment maintenance and replacement costs, and improving the reliability and stability of the entire power supply system.

[0110] In some embodiments, please refer to Figure 9 , the second DC conversion module includes: a third voltage adjustment module;

[0111] The third voltage adjustment module is electrically connected to the third anti-interference module and the load respectively;

[0112] When the power quality is less than or equal to a preset threshold, the second power supply component switches to the second DC conversion module to supply power to the load;

[0113] The third voltage adjustment module is used to adjust the voltage of the DC power supply after the anti-interference processing by the third anti-interference module to a preset voltage, obtain direct current, and transmit the direct current to the load.

[0114] The second DC conversion module receives the DC power signal from the second power supply assembly, adjusts its voltage, and ultimately delivers the adjusted DC power to the load. It is a key component in the system responsible for voltage adaptation and transmission, ensuring stable power that meets preset standards. The third voltage adjustment module adjusts the voltage of the transmitted DC power. By adjusting the voltage, it ensures that the current reaches a preset voltage level (the third preset voltage), ensuring that the power quality meets the load's requirements. The third diode, a unidirectional current-carrying element, transmits the DC power processed by the third voltage adjustment module to the load. It prevents current backflow and ensures stable current output in the intended direction. The third preset voltage is a preset voltage standard based on the load's power requirements. The third voltage adjustment module adjusts the DC power voltage to meet this standard.

[0115] The second DC conversion module receives DC power from the second power supply assembly and adjusts it to the required preset voltage through the third voltage adjustment module. First, appropriate DC power is sent to the second power supply assembly based on the load's power requirements. Within the second power supply assembly, the DC signal first passes through the third voltage adjustment module. The third voltage adjustment module is designed based on the load's power quality requirements to ensure that the provided voltage is both stable and meets the predetermined third preset voltage. After voltage adjustment, the third voltage adjustment module transmits the voltage to the third diode. The core of the third voltage adjustment module is to regulate the input DC power through switch control, voltage stabilization components, and filters. It can stabilize the output voltage according to changes in the input voltage and maintain the required preset voltage. This voltage adjustment process ensures that the output DC power meets the load's high power quality requirements. The adjusted DC current is output through the third diode. The third diode ensures unidirectional current flow, preventing backflow and thus ensuring stable power supply. The current passing through the diode is smoothly transmitted to the load, completing the power supply task.

[0116] This system automatically adjusts voltage and monitors current without human intervention, reducing the risk of human error and improving system management efficiency. This automated, intelligent management approach makes power system operation more efficient and precise. This design provides a stable, high-quality power supply, meeting the power needs of diverse loads and ensuring long-term, stable operation of the equipment.

[0117] In order to better understand the second power supply component, Figure 10 As shown, Figure 10 This is a structural diagram of another second power supply component provided in an embodiment of the present application. The second power supply component has two high-voltage DC (400V / 800V) inputs. First, the voltage input passes through the EMI and buffer circuit to filter out part of the 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 a DC / DC non-isolated voltage regulator with diode 1 output, and path B is directly output through diode 2.

[0118] This topology saves space and cost by sharing EMI and snubber circuits on two output paths. If the grid input quality is high, the ATS can be used to switch to output path B, ensuring the highest output efficiency. If the grid quality is poor, the voltage regulation solution on path A can be used to achieve high-voltage DC output. This architecture ensures that when the input voltage level is the same as the output bus voltage level, the use of diode-through switching eliminates the complex DC / DC or alternating current (AC) / DC conversion process, significantly improving power supply efficiency. The retention of the ATS and isolated voltage regulation solution also provides compatibility with poor grid quality or inconsistent voltage levels.

[0119] 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 structural diagram of another first power supply assembly provided in an embodiment of the present application, wherein the first power supply assembly includes: a first DC conversion module, an AC conversion module, and an energy storage assembly;

[0120] a first DC conversion module for converting a DC power supply into a DC power supply and transmitting the DC power to a load; and an AC conversion module for converting an AC power supply into a DC power supply and transmitting the DC power to a load;

[0121] The energy storage components are electrically connected to the energy storage power supply and the load respectively;

[0122] The energy storage component is used to transmit stored energy to the load;

[0123] 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;

[0124] 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;

[0125] 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.

[0126] The first DC conversion module extracts DC power from the DC power supply and transmits it to the load's DC input. Its core function is to ensure stable DC output and, through voltage regulation, ensure that the power meets the load's requirements. The AC conversion module extracts AC power from the AC power supply and transmits it to the load's AC input. It supports conversion between different power systems, ensuring stable AC power supply. The energy storage component transmits the stored power to the load. Its primary function is to maintain normal load operation through stored power during a main power outage or power outage.

[0127] The first DC conversion module is connected to the DC power supply via low-resistance, high-precision wires. The module contains key components such as a DC anti-interference module and a DC voltage stabilization circuit. The anti-interference module uses a filtering network composed of inductors, capacitors, and other components to filter out high-frequency electromagnetic interference from the DC power supply. The voltage stabilization circuit utilizes a high-precision linear or switching voltage stabilization chip, along with external resistors, capacitors, and other components, to stabilize the input DC voltage within the voltage range required by the DC load. The AC conversion module connects to the AC power supply and includes an AC anti-interference module and an AC voltage stabilization circuit. The anti-interference module utilizes electromagnetic shielding and filter capacitors to mitigate external electromagnetic interference. The voltage stabilization circuit utilizes an automatic voltage regulator to stabilize the fluctuating AC voltage within the rated range. The output is connected to the AC power supply via the AC power line to the AC device power supply interface of the load. The energy storage component is connected to the energy storage power supply and consists of an anti-interference module and a voltage stabilization circuit. The anti-interference module uses appropriate filtering components to prevent interference during the energy storage power supply transmission process; the voltage stabilization circuit uses a voltage stabilization chip suitable for battery power supply characteristics to ensure stable output voltage, which is connected to the load through the energy storage power supply transmission line to power the load in an emergency.

[0128] By integrating three power transmission methods—DC, AC, and energy storage—the First Power Component can provide different types of power support based on load demand. This diversity effectively avoids the risks of power shortages or unstable power quality that can arise from a single power source.

[0129] In some embodiments, please refer to Figure 11 , the energy storage component includes: a fourth DC conversion module;

[0130] The fourth DC conversion module is electrically connected to the energy storage power supply and the load respectively;

[0131] 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;

[0132] Wherein, the fourth DC conversion module includes: a fourth voltage adjustment module;

[0133] The fourth voltage adjustment module is electrically connected to the energy storage power supply and the load respectively;

[0134] The fourth voltage adjustment module is used to adjust the voltage of the energy storage power supply to a preset voltage to obtain direct current (DC) power, and transmit the DC power to the load.

[0135] The fourth DC-DC converter module is a key subsystem within the first power supply assembly, specifically responsible for managing the energy output of the energy storage power supply. It ensures that the energy storage power supply can safely and stably provide power to the load devices in emergency situations such as utility power outages or main power failures, ensuring uninterrupted business operations. The fourth voltage regulator module is a core component within the fourth DC-DC converter module. Its primary function is to adjust the DC voltage of the energy storage power supply, ensuring that the output voltage remains stable at the preset voltage required by the load devices. Using high-precision voltage conversion technology, it provides precise power support to the devices. The circuit breaker plays a critical role in circuit protection and control within the fourth DC-DC converter module. Under normal circumstances, it provides on-off control of the circuit, ensuring normal current output. In fault conditions, such as overload or short circuit, it quickly disconnects the circuit, protecting the battery backup unit and the entire power supply system from damage.

[0136] The fourth voltage adjustment module is connected to the battery backup unit via low-resistance, high-precision wires, ensuring that battery power flows smoothly 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 that the preset voltage can be output stably even when the energy storage power supply changes. It is equipped with suitable inductors, capacitors, and other components on the periphery for filtering and voltage stabilization. The output of the fourth voltage adjustment module is connected to the input of the circuit breaker. The circuit breaker uses a miniature circuit breaker with high breaking capacity and fast response. It can withstand the maximum output current of the battery backup unit and quickly disconnect the circuit in the event of an overload or short circuit. The output of the circuit breaker is connected to the power supply interface of the load device to ensure normal current output.

[0137] In order to better understand the fourth DC conversion module, Figure 12 As shown, Figure 12 This is a structural diagram of a fourth DC conversion module provided in an embodiment of the present application. Figure 12 The fourth DC conversion module can be a bidirectional DC / DC module. This allows 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, thus supplying power to the load and stabilizing the output bus voltage. The buck-boost circuit topology of the bidirectional DC / DC differs from the LLC topology. The bidirectional topology is symmetrical, with four active MOS transistors and an LLC resonant cavity composed of a transformer, inductor, and capacitor. Through different control methods, the voltage can be both stepped up and stepped down simultaneously, allowing power to flow in both directions.

[0138] When the utility power outage or main power failure occurs, the energy storage power supply transmission module can be quickly connected to provide stable power support for the load equipment, ensuring uninterrupted business operation and reducing the risk of data loss and business interruption caused by power outages.

[0139] In order to better understand the first power supply component, Figure 13 As shown, Figure 13 This is another structural diagram provided by an embodiment of the present application. The first power supply component: A-line high-voltage DC (400V / 800V) input, B-line AC input (traditional three-phase AC 380V grid or traditional single-phase AC 220V grid), and the entire cabinet internal battery pack backup power (48V / 400V) as C-line. First, the B-line AC input is the same as the first case. The A-line high-voltage DC input is divided into A1 and A2 by the switching switch ATS. Similar to the second case, A2 is used as a direct pass-through solution when the grid and the pre-stage voltage regulation are in good condition, and A1 is used as a backup isolation and voltage regulation solution.

[0140] Three diodes prevent backflow on lines A1, A2, and B. The highest voltage among the three lines is used as the output, while the remaining lines serve as backup voltages. The battery backup module within the cabinet serves as line C, connected to the output bus via a bidirectional DC / DC converter via a circuit breaker. In this AC / DC input power supply architecture, high-voltage DC is most efficient, so it is recommended to use line A as the primary power supply and line B as the AC backup power supply. Since the load front-end typically uses a Panama power supply or HVDC module for voltage conversion, the input high-voltage DC is already regulated and isolated from the AC / DC voltages. Therefore, line A2 can be connected with diode 2 for maximum efficiency. In this case, the battery backup power supply on line C is connected, and the bidirectional DC / DC converter further stabilizes the high-voltage DC. In other words, lines A2 and C are preferred for normal operation. If grid quality is poor and the battery cannot maintain voltage, line A1 is switched. The less efficient AC input on line B serves as the backup power supply.

[0141] This system adapts to any load power supply architecture with AC / DC input, including one AC / DC input, two DC inputs, and one DC / AC plus energy storage. It enables efficient direct flow of high-voltage DC power with high power quality, while also providing stable voltage conversion for low-quality power. Leveraging the internal battery backup unit (BBU) module, bidirectional DC / DC improves the power quality of high-voltage DC power at the cabinet level.

[0142] According to the embodiment of the present application, the present application also proposes a power supply method, such as Figure 14 As shown, Figure 14 This is a flow chart of a power supply method provided in an embodiment of the present application. The method is applied to a power supply system, and the method includes the following steps:

[0143] Step 101: Obtain the power supply demand of the load.

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

[0155] If the power supply demand of the load only includes the first power supply demand and the load does not have energy storage power supply, switching to the first power supply component without the energy storage component.

[0156] In order to better understand the choice of power supply architecture for data centers, Figure 15 As shown, Figure 15 A flow chart of the selection of a power supply architecture for a data center provided in an embodiment of the present application first determines the characteristics of the incoming line of the data center, AC / DC input or high-voltage DC input, and then designs and selects the power supply architecture according to conditions such as power quality and whether there is a backup power BBU module; wherein, the data center is the load, the power supply architecture is the power supply component, the BBU module is the energy storage component, the first architecture is the first power supply component without the energy storage component, the second architecture is the second power supply component, and the third architecture is the first power supply architecture with the energy storage component.

[0157] Since the embodiments of the power supply method and the power supply system correspond to each other, the embodiments of the power supply method can be found in the description of the embodiments of the power supply system, and will not be repeated here. The embodiments of the power supply method have the same beneficial effects as the power supply system mentioned above.

[0158] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method.

[0159] The embodiment of the present application further provides a power supply device, Figure 16 A schematic diagram of the structure of a power supply device provided in an embodiment of the present application is shown in FIG. Figure 16 Shown, including:

The second power 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 of different power qualities into DC power. The control component switches the first power component and / or the second power component to supply power to the load according to the power supply demand of the load, so that the first power component and the second power component can adapt to the different power supply demands of the load, thereby improving the compatibility of the power components.
