DISPOSITIF DE CONVERSION D'ENERGIE

摘要

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