  • METHOD FOR POWERING A MAGNETIC COUPLER AND DEVICE FOR POWERING AN ELECTRIC DIPOLE
    Publication number: 20100315187
    Abstract: A method for powering a magnetic coupler, in which: a) each winding of a first magnetic elementary cell is powered such as to produce a magnetizing flux in a bar of the first cell which is joined with a second cell, the fundamental component of which has an angular offset xi; and b) powering each winding of the second cell such as to produce a magnetizing flux in the bar of the second cell which is joined with the first cell, the fundamental component of which has an angular offset xj. The absolute value of the difference between the angular offsets xi and xj is greater than or equal to (I) rad.

  • Method and device for supply to a magnetic coupler
    Patent number: 7847535
    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.

    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 (in 34) 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.
