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.

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: A device converting electric power between a voltage source and a current source, comprising several stages (8i) of switching cells (10i,k) comprising each two switches (12i,k, 14i,k), capacitors (20i,k) associated with the cells (10i,k) arranged in a row (18k) increasing from current source (4), control devices (16i,k) each connected to a cell (10i,k) and elements for monitoring the control devices (16i,k) . The stages (8i) define two end groups and at least an intermediate group of switches, the two end groups comprising switches of each cell belonging respectively to the first and last stage connected in series, the intermediate group comprising pairs of switches (12i,k, 14i?1,k) of cells belonging to two neighbouring stages connected in series. Furthermore, the capacitors (20i,k, 20n,k) of a common row (18k) are transversely connected in series between the two end groups.
