Abstract
Device for reversible conversion of electric power capable of being connected between at least an input alternating voltage source and at least a load forming an output alternating current source, each input alternating voltage source having a supply terminal and a neutral terminal. The device comprises at least a switching block and includes an input terminal for connecting the supply terminal, a single reference terminal and an output terminal. Each switching block consists of a switching matrix formed of capacitors and switching cells, individually controlled. Each reference terminal is connected to a reference point other than the neutral terminal, and each block comprises elements for permanently maintaining at a constant or null sign the difference of potential between the first input terminal and the reference terminal.
