Description

Technical Field

[0001] This utility model relates to the field of common mode inductor technology, and in particular to a common mode inductor for assembled high frequency transformers. Background Technology

[0002] With the increasing frequency and integration of electronic devices, electromagnetic interference (EMI) problems are becoming more and more prominent. In particular, in the application of high-frequency transformers, common-mode interference has become one of the main factors affecting the stability and reliability of equipment. As the core component for suppressing common-mode interference, the design optimization and assembly method of common-mode inductors are directly related to the performance of high-frequency transformers.

[0003] The common-mode inductors used in existing high-frequency transformers generate a lot of heat during operation. However, due to the structural limitations of the common-mode inductor itself, its heat dissipation capacity is weak, which can easily lead to overheating of the inductor and thus affect its service life. This not only leads to a lot of time and production resource waste, but also increases the complexity and uncertainty of system operation. Furthermore, the lack of adjustable devices means that different inductors must be replaced when the working environment or equipment layout changes, resulting in high initial investment costs and reduced system flexibility.
