Abstract:
1. Method for supplying a magnetic coupler by using N periodic supply currents or voltages which are offset angularly relative to one another, the angular offsets between the N supply currents or voltages used being regularly distributed between 0 and 2π rad, N being an integer greater than or equal to four, the magnetic coupler comprising a plurality of pairs of windings, each pair being formed by first and second adjacent windings which are connected magnetically to one another by means of a core made of magnetic material, the method additionally consisting of supplying the first winding of each pair with a supply current or voltage which is offset angularly by an angle α relative to the supply current or voltage of the second winding of the same pair, characterised in that the absolute value of the angle α is greater than or equal to for at least one pair of windings.
