In brief, the invention relates in particular to a converter () comprising a plurality of rectifier arms (), 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 () between its output terminals (S, S), the converter () also comprises a correction arm () 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 () comprising such a converter () and one or more active double bridges (), such that an output (S, S) of the active double bridges () is electrically isolated from the converter ().

An electrical power converter unit () includes: a first connection interface () comprising two leads () forming a DC input/output interface for connecting a first electrical device to the power converter unit, a three-phase rectifier power converter circuit () and a second connection interface () for connecting a second electrical device to the power converter unit. The second connection interface includes a switching unit () adapted to switch between:&#x2014;a DC input/output mode, in which first, second and third arms of the power converter circuit () are electrically connected together, forming one DC input/output; and&#x2014;an AC input/output mode, in which the arms are disconnected from each other, forming separate input/outputs for a three-phase AC voltage.
