Common-mode and differential-mode integrated inductor

The utility model discloses a common-mode and differential-mode integrated inductor, which comprises a base, a magnetic core, at least two coils and at least one magnetic strip, a cavity is arranged on the magnetic core, the magnetic core is arranged on the base, the at least two coils are wound on the magnetic core, and the at least one magnetic strip is arranged on the base and in the cavity ofthe magnetic core. The at least two coils are wound on the same magnetic core to change the magnetic flux loop, so that the common-mode and differential-mode inductors are integrated on the same magnetic core, the number of filter inductors is reduced, the PCB size is simplified, the energy consumption is reduced, and the circuit efficiency is improved. 本实用新型公开了一种共差模一体电感器，包括底座、磁芯、至少两个线圈和至少一个磁条，所述磁芯上设有空腔，所述磁芯设置于底座上，所述至少两个线圈缠绕于磁芯上，所述至少一个磁条设置于底座上、磁芯的空腔中。通过至少两个线圈缠绕于同一磁芯上，改变磁通回路，使共差模电感集成于同一磁芯上，减少滤波电感的数量，精简PCB尺寸，减少能源的消耗，提升电路效率。
