Description

technical field [0001] The invention relates to a power supply technology for a communication base station, in particular to a compatible switching power supply device. Background technique [0002] In the mobile communication base station, it is necessary to use the switching power supply device to convert the 220V, 50Hz mains frequency into -48V / +24V standard DC power to supply power to the base station equipment to maintain the normal operation of the equipment. When the mains power fails, it is necessary to use the high-frequency alternating current generated by the high-frequency generator, generally 100Hz, instead of the industrial frequency alternating current to continue to supply the switching power supply device to maintain the normal operation of the base station equipment. [0003] However, in some areas, such as remote mountainous areas, the power supply is tight, the mains power failure in the base station is frequent, and the AC input switching (switching betw...

AI Technical Summary

Problems solved by technology

[0003] However, in some areas, such as remote mountainous areas, the power supply is tight, the mains power outages in the base station are frequent, and the AC input switching (switching between power frequency / high frequency AC) of the switching power supply device is frequent. The compatibility of high-frequency alternating current and high-frequency alternating current makes the switching work more complicated

[0004] Moreover, the existing base station power supply guarantee measures are single. Once the mains power cannot be used normally, it can only rely on generators, and the workload of base station power generation is heavy.

[0005] It can be seen that the existing generator technology and working mode can no longer meet the needs of the development of communication services
