The present invention relates to an electrical system comprising at least one magnetic cell connected to an external grid system and comprising a filtering cell having a capacitor X (CDM1, CDM2, CDM3) and a capacitor Y (CY). Said electrical system comprises an array of switches, connected up-circuit of the capacitors X (CDM1, CDM2, CDM3) and Y (CY) of said filtering cell, said array of switches being configured such that:in a single-phase operating mode, the series-connected switches (S2, S3) on the unpowered phases (B, C) are open, and the switches (S1, S4) connected between the first phase (A) and the other phases (B, C) are closed;in a multi-phase operating mode, the series-connected switches (S2, S3) are closed and the switches (S1, S4) connected between the first phase (A) and the other phases (B, C) are open.
