The invention relates to a method for distributing the total power of an energy conversion device between at least two converters in said energy conversion device, the sum of the conversion powers of the converters being the total power of the conversion device, the energy conversion device converting energy between a first electrical entity and a second electrical entity, characterised in that: said at least two converters correspond to at least two portions of a ring (29), the portions being proportional to a predetermined power value of the respective converters (1) thereof, the combination of the at least two portions forming the whole ring; and in that the total power of the conversion device corresponds to an arc of the ring between the positions of a first slider and a second slider that are movable around the ring, and the distribution of power between the converters is determined by the positions of the first slider and the second slider that are movable around the ring.
