The system (4) has a main switching cell (6) including two main branches (14, 16) having respective main switches (T1, T2). A switching aid cell (10) includes two secondary branches (20, 22) having respective secondary switches (T3, T4). A connecting branch (24) connects the switching aid cell to the main switching cell, where the connecting branch includes a switching coil (L1). The switching aid cell includes a switching capacitor (C1) placed in parallel to one of the secondary switches, and another switching capacitor (C2) arranged in parallel to one of the main switches. |
