  • Patent number: 11664739
    Abstract: In brief, the invention relates in particular to a converter (100) comprising a plurality of rectifier arms (110), making it possible in particular to rectify AC electrical signals available on the electrical phases (U, V, W) of an electrical grid. To balance the electrical signals coming from the electrical phases (U, V, W) of the electrical grid, and to limit a modulation amplitude of the DC signal generated by the converter (100) between its output terminals (S1, S2), the converter (100) also comprises a correction arm (120) that determines an amplitude of electric current flowing in a neutral (N) of the electrical grid and that generates an opposing electric current of equal or if not close amplitude. The invention also relates to a two-way charger (10) comprising such a converter (100) and one or more active double bridges (200), such that an output (S3, S4) of the active double bridges (200) is electrically isolated from the converter (100).
