The invention relates to a rectifier arrangement (2) having at least three independent drive units. According to the invention, said three drive units comprise two four-phase rectifiers (41, 42) and three electric motors (6, 8), wherein said electric motors (6, 8) are connected at the terminals to output connections (U1, V1, W1, X1; U2, V2, W2, X2) of the four-phase rectifiers (41, 42) such that three output connections (U1, V1, W1;U2, V2, W2) each of one four-phase rectifier (41, 42) are connected to an electric motor (6) and the fourth output connections (X1, X2) of said four-phase rectifier (41, 42) are connected to a further electric motor (8). This results in a rectifier circuit (2) having a plurality of independent drive units constructed from a reduced number of rectifiers, wherein said rectifiers are designed having four phases. |
