<p>The invention concerns a device for reversible conversion of electric power capable of being connected between at least an input alternating voltage source (11 to 1n) and at least a load (41 to 4n) forming an output alternating current source (41 to 4n), each input alternating voltage source (11 to 1n) having a supply terminal (21 to 2n) and a neutral terminal (31 to 3n). Said device comprises at least a switching block (61 to 6n) and includes an input terminal (71 to 7n) whereto can be connected the supply terminal (21 to 2n) of the voltage source (11 to 1n), a single reference terminal (91 to 9n) and an output terminal (101 to 10n). The or each switching block (61 to 6n) consists of a switching matrix (121 to 12n) formed of capacitors and switching cells, individually controlled by means controlling their operation. The or each reference terminal (91 to 9n) is connected to a reference point other than said neutral terminal (31 to 3n) of said source (11 to 1n), and the or each block (61 to 6n) comprises means for permanently maintaining at a constant or null sign the difference of potential between said first input terminal (71 to 7n) and said reference terminal (91 to 9n) of the or each switching block (61 to 6n).</p> |
