Method for distributing the total conversion power between the converters of a multiple-converter conversion device

An energy conversion device for converting energy between a first electrical entity and a second electrical entity, the energy conversion device comprising:

• at least two converters;
• and
• a processing unit configured to implement a power distribution method across the at least two converters, comprising:
• progressively switching usage of the at least two converters according to a periodic sequence,
• each converter of the at least two converters being deactivated when not under load and being activated when under load,
• a sum of conversion powers of the at least two converters being equal to the total power of the energy conversion device, the energy conversion device converting energy between the first electrical entity and the second electrical entity, wherein:
• each converter corresponds to a term in said periodic sequence of period n, n being the number of converters in the energy conversion device,
• the periodic sequence corresponds to an ordered and looped sequence,
• the usage of each converter of the energy conversion device is switched progressively among the at least two converters, from activated to deactivated and from deactivated to activated, according to a progressive permutation of said periodic sequence to balance at least one of the conversion powers of the at least two converters over time, and
• said switching usage is by decreasing or increasing an output signal from each converter progressively among the at least two converters while the energy conversion device supplies a continuous conversion power.
