Abstract
A device for converting an input DC voltage into an output DC voltage having a predetermined value, includes a set of elementary components comprising: an input voltage source; two output nodes; and a plurality of energy-storing elements, each consisting of one battery or of a plurality of batteries connected in series or in parallel. The converting device further comprises a switching matrix, configured to connect the elementary components to one another in a periodic cycle composed of a plurality of phases so that, for each cycle: Each phase is associated with one different connection configuration chosen so that, in each energy-storing element, the amount of charge at the start of the cycle is equal to the amount of charge at the end of the cycle.
