ABSTRACT:
The invention relates to a method for supply to a magnetic coupler comprising several pairs of windings, each pair being formed from a first and a second adjacent paired winding, magnetically coupled to each other by means of a core of magnetic material. The method further consists of supplying the first winding of each pair with a supply voltage or current out of phase by an angle a with relation to the supply voltage or current for the second winding of the same pair. The absolute value of the angle a is greater than or equal to 4p/N for at least one pair of windings.
