At the same time, multiple power inputs can be seamlessly switched and integrated, and stable power supply can be provided to the loads of the base station, thereby improving the reliability of power supply.

[0040] In one embodiment, the modular switching power supply includes an AC access unit, a DC access control unit, a rectifier unit, an AC output distribution unit, and a DC output distribution unit; the first input of the AC access unit is connected to the mains power supply submodule, the second input of the AC access unit is connected to the generator power supply submodule, the first output of the AC access unit is connected to the AC output distribution unit, and the second output of the AC access unit is connected to the rectifier unit, which is used to receive the AC power output by the mains power supply submodule and the generator power supply submodule, and distribute the received AC power to the rectifier unit and the AC output distribution unit; the AC output distribution unit is connected to the non-communication load in the base station, and is used to convert the received AC power and convert the converted electric energy The rectifier unit is connected to the DC output distribution unit, and is used to rectify the received AC power into DC, and output it to the DC output distribution unit; the first end of the DC access control unit is connected to the lithium battery energy storage submodule, the second end of the DC access control unit is connected to the renewable energy power supply submodule, and the third end of the DC access control unit is connected to the stock power supply submodule, and is used to receive the DC power output by the lithium battery energy storage submodule, the renewable energy power supply submodule and the stock power supply submodule, and output the received DC power to the DC output distribution unit; the DC output distribution unit is connected to the communication load in the base station, and is used to convert the received DC power and distribute the converted electric energy to the communication load for power supply.

[0041] The modular switching power supply is mainly composed of the following key units: AC access unit, DC access control unit, rectifier unit, AC output distribution unit and DC output distribution unit.

[0042] Specifically, the AC access unit is responsible for receiving AC power from the mains power supply submodule and the generator power supply submodule. The unit has two inputs and two outputs. The first input of the AC access unit is connected to the mains power supply submodule to receive the mains power. The second input is connected to the generator power supply submodule to receive the AC power of the generator. The first output is connected to the AC output distribution unit to supply power to the non-communication load of the base station. The second output is connected to the rectifier unit to send the AC power to the rectifier for processing.

[0043] The rectifier unit rectifies the received AC power into DC power. The efficient conversion of the rectifier unit is crucial for the subsequent DC output. The rectifier unit outputs the rectified DC power to the DC output distribution unit.

[0044] When the mains or generator is powered, the AC access unit receives the input AC power. Through intelligent control, the system can reasonably distribute the AC power to the rectifier unit or directly supply non-communication loads according to the power supply situation. The rectifier unit converts the received AC power into DC power, which can provide a stable power supply for subsequent DC power distribution.

[0045] The AC output distribution unit converts the received AC power and distributes the power to non-communication loads in the base station (such as air conditioners, lighting, etc.), ensuring that these devices receive a stable power supply. The unit distributes the received AC power according to the load requirements.

[0046] The DC access control unit integrates inputs from multiple DC power modules to ensure effective power management. The first end of the DC access control unit is connected to the lithium battery energy storage submodule to receive stored DC power. The second end of the DC access control unit is connected to the renewable energy supply submodule to receive DC power provided by renewable energy sources such as solar energy or wind energy. The third end of the DC access control unit is connected to the stock power supply submodule to receive DC power from other stored power sources. The DC access control unit outputs the received DC power to the DC output distribution unit.

[0047] The DC output power distribution unit distributes the integrated DC power to the communication load of the base station (such as the signal transmission and receiving equipment of the base station). The output voltage and current are dynamically adjusted according to the needs of the communication load to ensure the stable operation of each communication equipment.

[0048] The modular design ensures efficient energy conversion, reduces energy loss and improves overall system efficiency.

[0049] In one embodiment, the AC access unit includes a first AC access subunit and a second AC access subunit; the input of the first AC access subunit is connected to the AC power supply submodule, and the output of the first AC access subunit is respectively connected to the rectifier unit and the AC output distribution unit, for receiving the AC AC power output by the AC power supply submodule, and distributing the received AC AC power to the rectifier unit and the AC output distribution unit; the input of the second AC access subunit is connected to the generator power supply submodule, and the output of the second AC access subunit is respectively connected to the rectifier unit and the AC output distribution unit, for receiving the generator AC power output by the generator power supply submodule, and distributing the received generator AC power to the rectifier unit and the AC output distribution unit.

[0050] The AC access unit is one of the core components of the modular switching power supply. It is responsible for managing and distributing AC power from different sources to meet the power supply requirements of the base station load. The unit is mainly composed of two subunits: the first AC access subunit and the second AC access subunit.

[0051] The input end of the first AC access subunit is directly connected to the mains power supply submodule, which is mainly responsible for converting the mains power into AC power suitable for the base station.

[0052] The output end of the first AC access subunit is connected to two main power processing units: converting the received AC mains power into DC power and supplying the DC load; and directly distributing the AC power to non-communication loads (such as air conditioning, lighting, etc.).

[0053] The main task of the first AC access sub-unit is to receive the AC power from the mains power supply sub-module and distribute it to the rectifier unit and the AC output distribution unit as needed.

[0054] Under normal operation, when the mains power supply is stable, the non-communication loads of the base station (such as air conditioning and lighting) will give priority to using the AC power supplied by the mains.

[0055] The input end of the second AC access subunit is connected to the generator power supply submodule, which can be used to provide backup power when the mains power is unavailable. The output end of the second AC access subunit is also connected to the rectifier unit and the AC output distribution unit.

[0056] The second AC access subunit is responsible for receiving the AC power output by the generator power supply submodule and distributing it to the rectifier unit and the AC output distribution unit. When the mains power is unavailable or the power supply is unstable, this unit will take over the power supply to ensure that the base station can continue to be powered, especially for the support of critical loads.

[0057] In one embodiment, the DC access control unit includes an energy storage access control subunit, a renewable energy access control subunit and a DC power supply access control subunit; the input of the energy storage access control subunit is connected to the lithium battery energy storage submodule, and the output of the energy storage access control subunit is connected to the DC output distribution unit, so as to transmit the received DC output of the lithium battery energy storage submodule to the DC output distribution unit; the input of the energy storage access control subunit is connected to the renewable energy power supply submodule, and the output of the energy storage access control subunit is connected to the DC output distribution unit, so as to transmit the received renewable energy DC output of the renewable energy power supply submodule to the DC output distribution unit; the input of the energy storage access control subunit is connected to the existing power supply submodule, and the output of the energy storage access control subunit is connected to the DC output distribution unit, so as to transmit the received DC output of the existing power supply submodule to the DC output distribution unit.

[0058] The DC access control unit is an important component of the modular switching power supply. It is mainly used to manage and distribute power from different DC power supplies to ensure stable power supply for various loads in the base station.

[0059] The main function of the energy storage access control subunit is to transfer the DC output power of the lithium battery energy storage submodule to the DC output distribution unit.

[0060] The input end of the renewable energy access control subunit is connected to the renewable energy supply submodule, which is responsible for receiving electricity from renewable energy sources such as solar energy and wind energy. The output end is also connected to the DC output distribution unit to ensure that the electricity from renewable energy can be directly supplied to the base station.

[0061] The DC power access control subunit connects the DC power output of the existing power module to the system to provide additional power support, especially when the supply of lithium battery energy storage and renewable energy is insufficient.

[0062] The DC access control unit integrates lithium batteries, renewable energy and existing power sources to achieve effective utilization of multiple power sources and provide a stable power supply for the base station.

[0069] In one embodiment, the management and control unit is further used to monitor the input and output currents of each module in the modular switching power supply.

[0070] By real-time monitoring and adjustment of current, the management and control unit can effectively reduce system fluctuations caused by load changes and enhance system stability and reliability.
