[0003] After the power supply is modularized, it is difficult to achieve perfect electromagnetic compatibility measures due to volume limitations. The common switching interference and electromagnetic radiation of ordinary switching power supplies still exist or even become more serious. It is necessary to install a power filter at the front or rear stage of the power module. Meet the normal operation of the overall equipment and meet the requirements of electromagnetic compatibility characteristics
[0004] The power filter currently on the market cannot be completely matched with the power module. For example, the height of the standard brick power module is 12.7mm, while the height of the general power filter is 16mm~120mm, resulting in the height of the power filter and the power module. Inconsistency takes up a lot of space, which is not conducive to improving the space utilization rate of the overall equipment

[0031] See figure 1 In this embodiment, a brick-type filter module 10 is provided. The brick filter module 10 is used to filter the standard brick power module 200 to filter out interference signals such as switching interference and electromagnetic radiation that are commonly present in the power module, while reducing its own volume, adapting to the standard brick power module 200, saving equipment Space to improve space utilization.
[0032] The brick filter module 10 includes a housing 101 and an internal circuit 100. The internal circuit 100 is packaged inside the housing 101.
[0033] In this embodiment, the shape and size of the housing 101 of the brick filter module 10 matches the shape and size of the standard brick power module 200. That is, the length, width, and height of the standard brick power module 200 are the same. For example, the length can be 116.8mm, 61.0mm, 60.3mm, 57.9mm, 25.4mm or other sizes, the width can be 61.0mm, 57.9mm, 36.8mm, 25.4mm, and the heig...

[0051] This embodiment provides a power supply assembly. The power supply assembly includes a standard brick-type power supply module 200 and a brick-type filter module 10. The output end of the standard brick-type power supply module 200 is electrically connected to the input end of the brick-type filter module 10 for filtering Interference signals of the standard brick power supply 200, such as high-frequency interference, electromagnetic radiation signals, etc.
[0052] It should be noted that the structural composition and basic principle of the brick filter module 10 provided in this embodiment are substantially the same as those of the brick filter module 10 provided in the first embodiment. For a brief description, this embodiment will not be described in detail. For the similarities not described in this embodiment, please refer to the related content in the first embodiment.

Abstract
The invention provides a brick-shaped filter module and a power supply component, and relates to the technical field of power sources. The brick-shaped filter module comprises a casing and an internalcircuit; the internal circuit comprises a first differential mode filter module, a first common mode filter module, a second common mode filter module and a resonance filter module; the first differential mode filter module used to filter out differential mode interference signals is connected with an output end of a power module; the first common mode filter module and the second common mode filter module are used to reduce common mode noise signals; the resonance filter circuit is used to reduce electromagnetic interference, and is capable of filtering out high-frequency interference effectively. The brick-shaped filter module can improve the quality reliability, simplify the structure compression volume, ensure the same height of the filter module and a brick-shaped power supply, and facilitate the same plane design and production of the equipment, thereby saving the space cost and the material cost, expanding applicable environments of the equipment because of the characters of miniaturization and high power, and having positive significance for miniaturization and densification of national defense industrial equipment and civil equipment.
Description
Technical field [0001] The invention relates to the technical field of power supplies, and in particular to a brick-type filter module and a power supply assembly. Background technique [0002] Standard brick-type power modules, such as standard full-brick power modules, standard half-brick power modules, etc., have the characteristics of high efficiency, high power density, and small size. They have been widely used in civil, industrial and military fields and have formed Standardization within the industry. [0003] After the power supply is modularized, it is difficult to achieve perfect electromagnetic compatibility measures due to the size limitation. The common switching interference and electromagnetic radiation of ordinary switching power supplies still exist or even become more serious. It is necessary to install a power supply filter in the front or rear stage of the power module. Meet the normal operation of the overall equipment and meet the requirements of electromagn...
