Abstract

The invention comprises: a primary winding, a second winding, a winding seat and a magnetic core group. The winding seat comprises a winding part and a channel; the winding part is used for holding the first winding and second winding; the magnetic core group is located the channel in the winding seat; the primary winding and second winding are insulated each other; a part of primary winding and a part of secondary winding are winded on the winding seat together; the flux leakage inductance of the transformer can be adjusted by adjusting the ratio of the primary winding to the second winding winded together.

Description

technical field [0001] The invention relates to a transformer structure, in particular to a transformer structure with adjustable leakage magnetic inductance. Background technique [0002] Transformers are electronic components that are often used in various electrical equipment. Please refer to FIG. 1 , which is a schematic structural diagram of a traditional transformer. As shown in FIG. 1 , the transformer 1 mainly includes a magnetic core assembly 11 , a bobbin 12 , a primary winding 13 and a secondary winding 14 . Wherein, the primary winding 13 and the secondary winding 14 are completely overlapped and wound up and down in the winding portion 121 of the winding base 12 , and are insulated and separated by, for example, an insulating tape 15 (isolation tape). The magnetic core group 11 is usually composed of a first magnetic core part 111 and a second magnetic core part 112. Partial structures of the magnetic core group 11, such as the axial core parts 111a and 112a o...
