The invention relates to an electrical system comprising at least one magnetic unit connected to an external grid system and comprising a filter unit having a capacitor X (CDM 1, CDM2, CDM3) and a capacitor Y (CY). The electrical system comprises an array of switches connected to an upstream of the capacitors X (CDM 1, CDM2, CDM3) and Y (CY) of the filtering unit, the array of switches being configured such that: in a single-phase mode of operation, series switches (S2, S3) on unpowered phases (B, C) are open and switches (S1, S4) connected between a first phase (A) and other phases (B, C) are closed; in a multi-phase operating mode, the switches (S2, S3) connected in series are closed and the switches (S1, S4) connected between the first phase (A) and the other phases (B, C) are open.
本发明涉及一种电气系统,包括连接到外部电网系统的至少一个磁性单元,并且包括具有电容器X(CDM1,CDM2,CDM3)和电容器Y(CY)的滤波单元。所述电气系统包括连接到所述滤波单元的电容器X(CDM1,CDM2,CDM3)和Y(CY)的上行电路的开关阵列,所述开关阵列被配置为使得:在单相操作模式中,未通电相(B,C)上的串联开关(S2,S3)打开,并且连接在第一相(A)和其它相(B,C)之间的开关(S1,S4)闭合;在多相操作模式中,串联连接的开关(S2,S3)闭合,并且连接在第一相(A)和其他相(B,C)之间的开关(S1,S4)断开。
