Patent ID: 8502634

Claim:
An inductive electronic module comprising: a planar core element having an inner limb ( 29 a , 55 a ) and at least two lateral limbs ( 33 a , 35 a , 37 a , 39 a ) assigned to the inner limb, one on each side, to which core element planar winding arrangements are assigned to form a transformer, wherein a first of the planar winding arrangements (TR 2 , TR 4 , TR 5 ) is implemented as a series circuit comprising two partial windings, of which a first partial winding is formed on a first of the lateral limbs and a second partial winding is formed on a second of the lateral limbs, the first and second partial windings having a winding number and a winding direction, which are configured such that a resulting magnetic flux of the first planar winding arrangement is cancelled in the inner limb, in particular it is 0, and a second of the planar winding arrangements (TR 1 ) is formed on the inner limb, magnetically decoupled from the first planar winding arrangement, characterized in that the inner limb has a first core section ( 29 a ) embodied for interacting with the second planar winding arrangement (TR 1 ), and a second core section ( 55 a ), which is provided spaced from the first core section on the core element and which is embodied for interacting with an additional planar winding arrangement (L 1 ), which forms a series connection with the second planar winding arrangement, wherein the second core section is embodied such that it implements a magnetically active air gap for the additional planar winding arrangement.
