Inductor

Abstract

The inductor is characterized in that i first wire harnesses are wound on a first support, (n-i) first wire harnesses are wound on a second support, and the winding direction of the i first wire harnesses on the first support is opposite to the winding direction of the (n-i) first wire harnesses on the second support, the (n-i) second wire harnesses are wound on the first support, the i second wire harnesses are wound on the second support, the winding track of the (n-i) second wire harnesses on the first support is the same as the winding track of the i first wire harnesses on the first support, and the winding track of the i second wire harnesses on the second support is the same as the winding track of the (n-i) first wire harnesses on the second support. The inductor provided by the embodiment of the invention can reduce leakage inductance of a common-mode inductor, the magnetic core cannot be saturated and fail, and normal filtering can be realized.

Description

technical field [0001] The invention belongs to the field of electrical equipment, in particular to an inductor. Background technique [0002] In electronic circuits, common-mode high-frequency interference will be generated. In order to eliminate such interference, common-mode inductance is often added to the circuit, but the existing common-mode inductance has too large leakage inductance, and the magnetic core is prone to saturation and failure. , resulting in failure to filter, and will also affect the filtering effect of the differential mode inductor. Contents of the invention [0003] In view of the above problems, the present invention proposes a common mode inductor, including n first wire harnesses, n second wire harnesses, a first bracket and a second bracket; [0004] The i first wire harness is wound on the first bracket, the (n-i) first wire harness is wound on the second bracket, and the winding direction of the i first wire harness on the first bracket is ...
