Patent ID: 8896403

Claim:
An inductive electronic module comprising: a core element having an inner limb ( 12 ; 29 a ) and at least two lateral limbs ( 14 , 16 ; 33 a , 35 a ; 37 a , 39 a ) associated with the inner limb on both sides, said core element being provided with windings (N 1 , N 2 , N 3 , N 4 ) for forming a transformer, wherein a first winding (N 1 , N 2 ; 47 , 49 ; 51 , 53 ) is implemented as a series connection composed of two partial windings, of which the first partial winding is formed on a first lateral limb and a second partial winding is formed on a second lateral limb, the first and the second partial windings have a number of turns and a direction of turn which are designed such that a resulting magnetic flow of the first winding is cancelled in the inner limb, and in particular is zero, and a second winding (N 3 ; 40 , 42 ) is formed on the inner limb, wherein, in order to implement a transformer that is magnetically decoupled from the other windings respectively, the first and/or the second windings comprise at least two conductors which can be contacted separately from one another, characterised by a fourth winding (N 4 ) which extends across two lateral limbs provided on both sides of the inner limb.
