Electronic component, in particular three-phase transformer for an isolated voltage converter

Electronic component, comprising:

• a magnetic circuit,
• two electrical conductors each having a portion arranged around one and the same portion of the magnetic circuit, each of said portions of the electrical conductors forming a winding between a first and a second end, these two windings being inductively coupled to one another via the magnetic circuit, and
• a support of the two electrical windings, arranged between said electrical conductors and said portion of the magnetic circuit,
• this support comprising:
• a wall around which the electrical windings are arranged, and
• three flanges offset along the longitudinal axis of the support so that one of the electrical windings is arranged between the first and the second flange and that the other of the electrical windings is arranged between the second and the third flange,
• wherein at least one step is made in the height of the first flange so as to locally reduce the height of the first flange, this step extending radially at least from the radially inner edge of the first flange.
