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.
